The problem is that it doesn't complete the update. It stops at 30% and removes what it did update. Its a never ending cycle it seems.This sounds like the 8.1.1 patch in which case yes it is a big patch.
I did and I fixed it!anti-virrus, bios lock or a dozen other things could be blocking it... bit hard without details.
Have you tried running the update patch in safe mode?
I would suggest disabling them.
Yes, but I HAVE seen a lot of computer's get a BSOD after these updates. Happened to my friend WHILE WE WERE in SCHOOL. Luckily I knew a trick that didn't make much sense to me, but it worked to fix it.I am glad that the problem is solved, as it seems many anti-virus programs were causing the discrepancy. Disabling Windows Updates on the whole is an all-around bad idea. Mostly because these updates do contain critical security vulnerability patches that can have a serious detrimental impact to a large number of computers. One of the reasons Microsoft committed itself to releasing security updates every month were the serious a prolonged security problems with unpatched versions of Windows XP. Good thing that things have changed since then.
