Windows update KB3004394 causes the following issues on my Windows 7 x64 Ultimate system:
All MMC functions (Event Viewer, etc.) now require Administrator action, although in an Administrator account.
Windows Defender service will not start
The Windows Defender Service Terminated with the following error
%%-2147023113
Removing it returns the system to normal.
Anyone else experience this?

2014-12-10T22:33:01+00:00 and there was another problem. I had done one of my own pcs and when rebooting I lost the internet. I had a red x on the internet icon. I then removed this update- rebooted, internet back. This is a real nasty one and Microsoft needs to fix this. Btw when I rebooted and windows asked me to install it again it said it was "important" not critical but I hid it anyway.

2014-12-10T22:17:41+00:00 not only did removing the update fix the problem with other updates not installing, but also popped up with 108 additional updates that weren't showing previously (this is a new install) Only common thread I'm seeing is this just seems to be affecting new installs, not upgrading existing. I have 200+ other PCs, Laptops and servers that updated just fine, just this one new install that showed this issue.
