How to start System Restore by using the Command prompt
Note You must be logged on to Windows with a user account that is a computer administrator to complete these steps. To verify that you are logged on to Windows with a user account that is a computer administrator, visit the following Microsoft Web site:

If a new program has made your computer behave unpredictably, and uninstalling the new program did not help, you can try the Windows XP System Restore tool.

Important If you have not previously set a restore point in System Restore, you cannot restore your computer to a previous state. If you are not sure, or if you have not previously set a restore point, contact Support.

To start System Restore using the Command prompt, follow these steps:
Restart your computer, and then press and hold F8 during the initial startup to start your computer in safe mode with a Command prompt.
Use the arrow keys to select the Safe mode with a Command prompt option.
If you are prompted to select an operating system, use the arrow keys to select the appropriate operating system for your computer, and then press ENTER.
Log on as an administrator or with an account that has administrator credentials.
At the command prompt, type %systemroot%\system32\restore\rstrui.exe, and then press ENTER.
Follow the instructions that appear on the screen to restore your computer to a functional state.
Note To start the System Restore tool using another safe mode option, visit the Microsoft Help and Support Web site and see the article "A description of the Safe Mode Boot options in Windows XP."
