Sfc scannow

Hi all!

I have run sfc scan now (because the startup of win xp was slower than before ( i count the 3 blue bars when xp is loading, and it was increased from 6 to 11) and asks the win xp cd. after the check, I rerun the sfc scannow, to be sure that everything is ok, but asks again for winxp cd (there is still corrupted files?). I run sfc /purgecache, then again scannow to refill the cache, and after i rerun the scannow it still asks for the xin xp cd!!! what is going on here?????

(note that i have win xp pro gr without sp2, after the installation i installed sp2. I re instaled the sp2, rerun the sfc /purgecache , then scannow, and again the scannow and still asks for the win xp cd.)

Scannow isn't necessarily replacing files each time it runs. It wants the CD to do comparisons.

If the sfc scan has completed, the system files should be fine.

There are some other scans you can run to compliment the sfc scan, and help speed up your system.
start-->run-->chkdsk /r

Download ccleaner, and use the registry tool to scan and fix all issues. You may need to run it several times to resolve all the issues.

There is also a malware guide in my signature to remove any traces of infection.

If you're concerned that the sfc scan isn't repairing the system files, you can do a windows repair. That will replace all the system files using the XP disc. Here's a description of what it is, and how to do it. I've got a guide in there that contains screenshots of the repair.

It won't effect user data or 3rd party apps, but it will wipe out the MS updates. A visit to the MS update page can fix this.
