Reinstalling System Restore
Click Start, Run and type %Windir%\INF
Locate the SR.INF file. If you have configured Windows Explorer to hide known file extensions, the file may show up as SR. To see the file extensions for all file types, then try this:
On the Tools menu in My Computer, click Folder Options.
Click the View tab.
Clear the Hide extensions for known file types check box.
Right-click the SR.INF file, and then click Install
Windows will now attempt to reinstall System Restore, and may prompt you for the Windows installation source path. Point to %Windir%\ServicePackFiles folder, or insert your slipstreamed Windows XP (matching the Service Pack level of your system.)
System Restore core files will be reinstalled. Restart Windows when prompted.
Alternately, you can reinstall System Restore using the following command line:
