My wife's Laptop (Toshiba) runs Windows 7 Professional X64.
For reasons unknown, 3 separate technicians - after 4 hours of trying to figure this out - could not understand why WINDOWS UPDATE would crash and burn, giving the Error Code: 80073712.
We even created a dummy administrator "TEST" account; and Windows Update displayed the same error.
I know of only one thing left: to somehow reinstall Windows 7 Pro X64 over itself (but that does not guarantee Windows Update will work)?!
PLEASE! If anyone can help me fix this, I would be extremely grateful.
(MY WIFE IS NOT HAPPY NOW - AND THAT SCARES ME?! LOL)
