When I try to use system restore in XP I get a message saying 'The application or dll:\windows\system32\mshled.dll is not a valid windows image. Please check against installation diskette' The problem started when my system froze during a restore process.
Sometimes the system files (those required to run Windows properly) can become corrupted.
Here's how to run a check on your system files: Click Start; Run. In the Run box, type cmd.exe to open the command prompt window. At the prompt, type SFC.exe /scannow (note the space between sfc.exe and /scannow). Press ENTER.
If Windows finds problems with the system files, you will be prompted to insert your Windows XP installation CD to restore the files.
If no problems are found and the scan finishes, type exit and press ENTER.
