Re: If only that were true...
IMPORTANT UPDATE!
I've figured out how Microsoft is doing this: They keep reissuing KB2952664 with different revision numbers then marking the update as "essential", forcing Windows to download and install it automatically without user intervention and even if you marked a (previous) revision as "Hidden".
If you check
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\PackageIndex\Package_1_for_KB2952664[~31bf3856ad364e35~amd64~~0.0.0.0]
(numbers enclosed in [...] may change)
plus numerous other registry keys, you'll find the various revisions that your computer has been forced to download and install, each one seen as "separate" and individual due to the revision number but, of course, exactly the same.
