The System Restore feature in Windows XP is a great one - but sometimes it quits working properly (or at all). In this case, you may need to reinstall it. Here's how:
1. Click Start | Run.
2. In the Run box, type %Windir%\INF. This should open your WINDOWS directory to the INF folder.
3. Find a file named SR.INF (if you have Explorer configured to hide common file extensions, it may display as SR).
4. Right click the SR.INF file and select Install. Windows may prompt you for your Windows installation source path. If you have service packs installed, point it to the %Windir%\ServicePackFiles folder.
After the System Restore files are reinstalled, restart Windows.
