Hi Stan, Within the last couple of months there has been an evil malware/fraudware trojan running around that, when it is eliminated by some antivirus packages leaves behind a somewhat neutered registry. It's one of the trojans that lies to you about your computer having lots of bad stuff, and buy our tool and get rid of it. In its native form, it disables any internet explorer functions. Recent updates to antivirus packages seems to kill it, but part of the isolation also leaves behind a bad registry value. The indicator is that if you try to set your Windows Update to Auto, it won't take. When you go out to Microsoft and ask for an Update, it will come back and ask to set your update to Auto, but then it gives an error message (I don't have it handy right now). If you do get that sort of behavior, and do a Google search on the error, you'll get advice on the exact command to run in the Run selection on the Start Menu. Basically, it uses regsrvr to re-enable the Windows Update in the registry, which also enables getting to Microsoft. I got hit with this sucker four times in a weekend until my antivirus packages got smart. Good luck!

I did a google on microsoft and every entry I click on says the address cannot be found. I also tried entering microsoft.com with the same result. Could my pc have been invaded by something preventing me from accessing microsoft?
