Vista Device Manager can't open

1

I am trying to access the device manager from the control panel, and I am getting this error from the MMC window:

MMC could not create the snap-in. The snap-in may not have installed correctly Name: Device Manager CLSID: {74246BFC-4C96-11D0-ABEF-0020AF6B0B7A}

Do anyone know how to fix this?

This is on a Windows Vista 32, Spyware clean computer.

Go to command prompt and type

SFC /SCANNOW

This should scan and fix any errors with Windows system files.

I have only seen this issue twice, once doing the above fixed it and the other time, I tried diagnosing for hours without coming up with a solution and had to reinstall Windows from scratch.

Lastly, I think this is caused by a corrupt registry key. I never worked out what actually made the problem but it may be worth doing a system restore if you have it turned on as it is possible that it may have created a point before this was an issue.

Hopefully the above will help.
