I am right up to date with the critical updates on my Windows XP
Professional system.

However, I've just had some problems with spyware deleting at least one
system file (notepad) and so, following a tip in a forum, I ran the System
File Checker to check whether any other system files had been deleted or
replaced. I used the command:

sfc /scannow

which called for my original installation CD. Except for the progress bar,
the System File Checker did not report any missing files, or indicate that
it had replaced any file. (Is there a log somewhere of what it did?)

However, it has now occurred to me that, if it did replace any files, it
might have undone some of the critical updates. Might this be correct? If
so, what is the simplest/quickest way of restoring the critical updates?
Although the Windows Update site allows you to view your installation
history, it does not give you the option simply to reapply the updates.

Do I have to uninstall as many of the updates as I can from Add/Remove
programs, and then reinstall them? If I do uninstall them all, can I use
the Windows Update site to reapply them?
