Garran: I can't be sure whether this one's the cause ( https://support.microsoft.com/en-us/kb/3112343 ), but the fact that it just came out today and more or less has a 'supports new update scenarios, does a better job as spyware, blah blah' description makes me think it's suspect. It's rated as Important, so it would get installed if you haven't given yourself some form of manual control.
The other possibility is that one of the earlier updates re-enabled itself or at least un-hid itself (which would make it auto-selected if it's Important or higher); the Win10 upgrade ones seem to be particularly insistent about coming back again.
Let me put it this way: I always check which updates I install (automatic updates turned off), I didn't install the update mentioned above and I have no nagging whatsoever. So chances are high you hit the nail on the head.The other possibility is that one of the earlier updates re-enabled itself or at least un-hid itself (which would make it auto-selected if it's Important or higher); the Win10 upgrade ones seem to be particularly insistent about coming back again.
