How to Repair Windows XP System Restore
System Restore is a very useful tool in Windows XP because it allows you to back up your computer system by creating a restore point you can come back to in case of system errors. It is an especially important tool when you need to repair your computer by removing viruses and other malicious parasites. There are times when the Windows XP registry becomes corrupt, much like other system components and requires a few troubleshooting steps to repair its functionality.
Start off by disabling System Restore. To do this, click the Windows "Start" button and click the "Control Panel."
Double-click "System" and click the "System Restore" tab. Place a check on "Turn off System Restore" and click "OK." Restart your computer.
Follow the same steps you used above to open the "System Restore" tab. Remove the check from "Turn off System Restore" and click "OK." Restart your computer again. Many times disabling and re-enabling System Restore will cause it function properly again. If that does not fix System Restore errors, move to the next step to reinstall it.
Click the Windows "Start" button and click "Run." Type "%Windir%\INF" (without quotes) and press "Enter." This will bring you to the Windows INF folder.
Locate the "SR.INF." If you cannot see the SR.INF file, click the "Tools" button and click "Folder Options." Click the "View" tab and remove the check from "Hide extensions for known file types." Now locate the SR.INF file and right-click it. Scroll through the right-click menu and click "Install." Windows XP will reinstall and repair System Restore. Restart your computer when prompted to.
