Windows File repair utility

CCleaner for Windows
1

I can't use the Windows file repair utility. When I try I receive a message saying, "Windows unable to access system".

Would appreciate any assistance to resolve.

(I'm not a technical expert !)

Am using Windows XP, 2002, S/P 3 and Kaspersky Internet Security 2009.

Thanks.

No problem was previously identified.

Just wanted to do some "tidy up" to keep system "healthy".
