I had the same problem I see others have had: When trying to use Windows
Update to download security updates, it said I would have to validate my
'Genuine' Windows. OK. So it downloads whatever and says it will now install.
After a few minutes it reports that the install failed! So it looks like the
update IS downloaded but just won't install. I go to the validation site and
all goes well. Still can't install. So I dig through component services,
looking for clues: logs say install failed! Thanks!
Anyway, to make this long story short, this solution worked for me:
Download this file and run it after shutting the browser down. Then restart
the browser (Internet Explorer).
