MAIN.CPL causes exception on boot - Sony laptop

[Nazbuster]

I get a diagnostic message that MAIN.CPL caused an exception every time I boot my Sony laptop. It doesn't seem to have any other adverse effects.

Can someone remind me where to find, and how to extract the original OS copy of MAIN.CPL to replace the current one? I assume it's corrupted.

Click Start/Run, type in sfc /scannow and heep your Windows-CD at hand.
That will check the whole PC for corrupt Windows files.

Or use expand CD-drive:\i386\main.cp_ c:\windows\system32\main.cpl in a command-window.
