Windows Registry

One of the most important programs of a windows operating system (XP, 2000, NT, 98, 95) is the Windows Registry that is also the brain of the operating system. When any software is installed or modified or accessed the registry values are changed to reflect any changes in user or the software settings.

The Windows registry is also the main reason for viruses. Modifying values in registry to disrupt programs is very easy by understanding basics of Windows registry. There is more than one method to modify the registry.

The most simplest way to modify the registry is by a simple method:

1. Understand the registry properly including the keys and values. You can get information at this site: http://support.microsoft.com/kb/256986
2. Write the change keys into a notepad file and save it as FileName.reg
3. Write a batch file containing list of commands to open the *.reg file
4. Write autorun for the batch file to run during startup of windows

Voila! You have successfully modified registry.

Other methods include visual basic scripting (vbs), java scripting (js) or C programs.

In my next post I will show a simple method to modify registry using the first method (reg bat method)
