There were two updates, KB2596615 & KB 2596856 that keep failing on my Vista system but not my XP or Win 7 laptop. They have to do with Office. I have an older version.
I tried to download and install them manually from the Microsoft site and I think that may have caused a big issue with my PC. I finally got it to boot up. That's the only thing I did that may have almost ruined my PC Startup.

I tired to find help on the Microsoft site but to no avail.

The error message I received was to do with 80070641. I finally have had to "hide" the updates to keep my PC from wanting to update then just to fail again and again.

Thanks for any hints or help.
