This is just a guess of potential problem with antivirus software. One of the recent (~12-09-14) Windows Update, specifically KB3004394 seems to be causing a host of problems (I noticed it because I run SFC scan after all WIndows Update, and it created false corrupt files.) Anyway it is causing a host of problems because it basically had a bug in changing root certificate of Windows system files. As someone wrote in response to https://answers.microsoft.com/en-us...4-issues/ace25277-7f65-4486-bc44-c1b106907a18 "Same thing here: KB3004394 removes/corrupted Windows Certificates so all windows system files are now found as unsigned. This is the reason why UAC comes into play and asks if you want to run an unknown program or file even when running the admin account, but only for system files. Seems this update corrupted the catalog folder/files within so windows now thinks all system files are unsigned" Based on that, the first thing that popped into my mind is that some antivirus programs might start finding Windows system files as threats and quarantine/delete them. And worst part is that with that update installed, a Windows system cannot get Windows Update - up have to uninstall that specific update to get additional updates (so how will MicroSoft fix this.) What do other think? Assuming that poster is correct, and this update made all WIndows system files unsigned, do you think some Antivirus programs might start treating WIndows files as malware threats until this is fixed?
"Restarted Window 8.1 today, Tues Dec 10 to install updates. PC is now locked up on "keep your PC on until this done. Installing update 19 of 22... Locked up for over 2 hours. Anybody know what I can do. Can I turn off PC and then turn back on? Thanks for any help you can give." "I don't know if its Silverlight or windows. I did the updates and now the whole metro page is blank, only have desktop. Also all restore points are gone and icons are all over the desktop page." http://answers.microsoft.com/en-us/...-bb71-4307-b5ef-5625f041a4a4?tm=1418221106903
Haha wow. Quality Control does that even exist these days at Microsoft, or is that not important at all anymore? "Its time to release the updates"..."but they are not tested Sir ? "..."I said release them!!!"
Even though I uninstalled the specific update, I decided to reinstall my last image. During its update, KB3004394 was no longer offered, but the same amount of Windows Security updates for x64 were offered. So I assume MicroSOft replaced the bad update with a different one (but if people cannot update with the bad one, I am not sure what will happen to people who did get the update and do not know to uninstall it.)
Once I Crashed so bad all I could get was the desktop, I used the Documents folder to maneuver to system32 and rstrui.exe and put a shortcut on the desktop, when clicked on produces the dialog box for system restore. After that I got acronis TI, now I have Macrium Reflect
seems this round of updates in general caused issues for some people. i even got a call today from a client telling me there office 2013 says its not activated anymore and this was a store bought boxed version they had me install for them. but on a few forums i saw people complaining about these updates.
I said from teh very beginning when stupid MS decided to push out updates with large file sizes to not only fix issues but also implement new features. My instinct told me it was a bad idea, because you don't want to patch a system heavily unless absolutely necessary. Now look at what happens. Shame on MS. these stupid programmers got high pay for such lousy work. Really a disgrace. Puke.
I guess you're locked out thanks to ValidateAdminCodeSignature as now you can't run regedit.exe elevated, right? It' my case. lol I wondered whether I should fix it via boot CD, but it seems I had better to rollback my system and don't install kb3004394 if it still displayed. (-。-)=3
I have a VM that took 18 hours to update with patches for Windows, Office and Visual Studio. You just have to wait for it to finish. And I would not install KB3004394.

KB3004394 got remove from WIndows Updates yesterday afternoon. I refreshed to recent image and it was no longer offered.
Try the Windows troubleshooter. Stopped working here after this update. Uninstalled it and voila - working again.
If F8 means safe mode, it wouldn't help me, but anyway I restored from boot CD. And good to know you restored, hide the corrupted update and could update OS w/out problem As already mentioned it seems that update was removed so maybe you can unhide that again.
