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?

    I got the same error on two machines, one being a fresh build. I removed KB3004394 and full computer functionality returned. I too stumbled upon a forum where people were discussing the update was breaking the troubleshooter which was another symptom I was having. Windows 7 Pro & Ultimate, both 64 bit.

    We were having problems using published applications (via RemoteApp). Clients were complaining about RDP.

    You could connect to the server, run the application from there, but you could not run the application that has been published by RemoteApp.

    Once I removed KB3004394 it worked.

    There's a bug report on Oracle's VirtualBox ticket system that seems to be caused by KB3004394. For some, uninstalling the update resolves the VirtualBox failures.

    VirtualBox Ticket 13677

    Had a look at the VirtualBox breakage.

    The problem seems to be that the update does not install any catalog file C:\Windows\System32\CatRoot and it's therefore impossible to verify the new crypto32.dll file that the it installs.  (Compare "sigcheck -i C:\Windows\System32\crypto32.dll" output before and after installing the update. Sigcheck says it's signed before and unsigned after.)

    The Windows 8.1 version of the update works, i.e. installs C:\Windows\system32\CatRoot{F750E6C3-38EE-11D1-85E5-00C04FC295EE}\Package_1_for_KB3004394~31bf3856ad364e35~amd64~~6.3.1.0.cat that we (and sigcheck.exe from microsoft/sysinternals) can successfully validate the DLL.  (I've only tried 64-bit Windows 8.1 and Windows 7, so I cannot tell exactly which updates are broken.)

    The only way to make VirtualBox work again is reverting/removing the update, unless Microsoft fixes the missing .cat file issue.  I sincerely hope that Microsoft will update the update with a working cat file eventually...

    PS. Would be really swell if files like crypto32.dll and wintrust.dll had embedded signatures instead of only external ones. It would not only do away with these kind of issues but also make it a lot easier to verify that the files haven't been tampered with.

    WMC PROBLEMS: I have two networked X64 windows 7 home premium computers running hd homerun cable card access. Cable tv content wouldn't play on either one. (Got following message: "Display driver error The video playback device does not support playback of protected content.")

    Restored to 12/6/14, then found forum on "The Green Button" isolating the culprit as KB3004394

    Reinstalled updates leaving that one out. Everything works again.
