Click Start>Find>Files or Folders.
In the "Named" box, type:
*.cpl
and in the Look In drop-down box, select the C: drive.
Click Find Now.
Maximise the window and click on the heading "In Folder" to sort the files by directory. Look at the files listed in the \Windows\System directory.
Double-click each file in turn...if some work, but one of the files gives you an error, that Control Panel file is corrupt.
To fix the error you must replace the .cpl file by extracting a new copy from the Windows CD.

If none of the .cpl files work and they all give the error, they may be disabled in the Registry, or the Control.exe file may be damaged or corrupted by a virus, and must be replaced.
