All about Registry
Before showing the tweaks you can make using windows registry.I would like to give a indepth tutorial on what is Registry ,how can we use it to suit our needs.
Definition:In simple terms "Registry is a hierarchial database where you can store information related to hardware ,System software(operating system),application software,system preferences and user preferences."
The hierarchial organisation of the database is divided into machine information,user information and software information.When the system starts it looks in the registry for the configuration settings of hardware and software installed.Its organisation depicts the directory-subdirectory concept in windows explorer. The registry is divided into six main divisions called HIVES which are inturn divided into keys and subkeys which contain values where information about software,hardware and users is stored.
The values are divided into 3 types they are DWORD,BINARY,STRING based on the usage.
DWORD is used for storing binary values where you can store list of values.Each value leads to different behaviour of OS,HARDWARE,APPLICATION SOFTWARE.String is used for human readable format.While BINARYis for storing raw data in hexadecimal format which contains hardware settings.
