Do you even know what the sfc program does, and in what cases it is (and isn't) useful?
In any case, while having all the latest updates installed is a good thing, it doesn't come even close to eliminating all of the risks associated with using Windows.
So, particularly if you use Internet Explorer, Outlook/Outlook Express, any file sharing/P2P programs, or MS Office... What sort of virus and malware protection do you have/use?
When I try to run it with the RUN command, all I get is a brief DOS window that shows for about a half a second, then nothing. It worked fine for a long time. Also I can't install the MSConfig Tool update to put the Tools tab option in the MSConfig window. Could these be related? I'm running SP2 with all the latest updates. Any input would be appreciated. Thanks in advance.
