Clearly it seesm that KB3004394 might well be causing problems. Just in case I retested this on my setup (also Win7/Ult/x64) and I still cannot reproduce the symptoms.

I will continue to follow this thread. Clearly my PC might be immune for some reason. Here are my specs, if anyone wants to know anything else about my PC just ask

Answer 3

I had trouble with this update also.  I restored my pc from a back-up, then installed the recent updates one at a time until I narrowed it down to KB 3004394.  To me this basically made windows 7 pro x64 ( my OS) into Windows Vista.  I uninstalled the update and blocked it.  Everything is back to normal.  I don't know what the intention of this update was, I hope Microsoft would shine some light on it with more info.

Just makes me wonder if this was Microsoft's attempt to get people frustrated and get them to move over to Windows 8... I'm just going to keep thinking that this is just a corrupted update.  I don't use Windows Defender at all.  I use Webroot Internet Security Anywhere and Malwarebytes Premium.  So far I have not had any issues with security.  I have faith that Microsoft will find a fix for this update.
