Personally, I'd like to know how this comes up. In my past three computers, two have finally been rendered useless by windows updates. In the first one, MSFT refused to assist in any way. In the second I spent a futile two hours hand-entering commands in the registry and getting nowhere. MSFT free updates generally cost me several hundred dollars.
OK, good news, I think. After trying several times with system restore, I FINALLY was able to restore my computer to an earlier time, right before the SECOND Windows update. I bring up Word, and now I CAN do a save.
With respect to your post, I discovered something: apparently I didn't need to do a system restore. Maybe all I needed to do was look at the "Review your update history" screen, and uninstall the latest ones?
I also have turned off automatic updates.
Thanks.
