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?

    Hi

    I have Windows 7 Ultimate x64 and KB3004394  was offered as an Important update for me and it installed successfully. It shows as a Recommended update afterwards in View update history. I did restart PC afterwards.

    I can open Event Viewer without the need for administrator password on both standard user and administrator accounts. UAC slider is set to default.

    Windows Defender service seems to be running for me:

    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.

    Same issue with Win Server 2008R2. Removing the update sorts it.

    MS monthly update cycle is becoming a joke, I can't remember the last issue free release :-(

    This comment from the VirtualBox ticket may help illuminate what's going on:

    From what I can tell, the KB3004394 update does not install a catalog file on 64-bit windows 7. It does on Windows 8.1 (C:\Windows\system32\CatRoot{F750E6C3-38EE-11D1-85E5-00C04FC295EE}\Package_1_for_KB3004394~31bf3856ad364e35~amd64 6.3.1.0.cat), so VBox works fine there.

    The result of the missing .cat file is that VBox (nor SysInternal's SigCheck.exe for that matter) is not able to verify the authenticity of c:\windows\system32\crypt32.dll and wintrust.dll. If we cannot find any valid signature for the files, we have to assume that they have been tampered with and are forced to abort application loading. These two dlls are important for validating other components, so there is absolutely no way we can ignore this.

    Until Microsoft fixes the KB3004394 update on Windows 7, the only solution is to revert/uninstall it.
