What exactly does KB2952664 do?

KB3035583 (nagware) just appeared in my Win 7 Windows Update.  Seventh time it appeared.

BDSolomon,

The free app called GWX Control Panel will make the registry settings you mentioned, and it will also make other settings to prevent Windows 10 from being installed.

For more information about GWX Control Panel, see this site ...

I just found something!

How to manage Windows 10 notification and upgrade options

https://support.microsoft.com/en-us/kb/3080351

It talked about how to modify it by computer configuration -- I had no idea what that was, but google told me it was gpedit (from RUN).

The path they gave was Computer Configuration/Policies/Administrative Templates and further... I found it but without the "Policies" entry.

Further down it said how to disable it via the registry.  I went there and it was already disabled.  Not sure if I had done it earlier, or if the group policy ended up setting it, but who cares, it's done.

They also had a registry key to disable the notification icon, but I don't know if you're s'posed to add a whole folder and a variable in it, so I skipped that.

MS updated my Office 365 this week.  Do you think they might have included "Get Windows 10" with that update?

Don't know ... but it's possible.

Is there a KB (or any other identifiable/searchable) number associated with the Office 365 update you received? If so, try searching on that number and the phrase:  Windows 10 ... so see if anyone else had a similar problem after getting Office 356 updated.

Is Office 365 updated automatically or do you have to click something to get the updates (Sorry for all these questions, I do not have Office 365). Is Office 365 updated via the Windows Update process, or some other process (such as settings within the app itself)? If Office 365 is automatically updated, you may want to find out if there is an option to manually control when the updates are downloaded & installed.

You should probably run the GWX Control Panel after any update from Microsoft.

As far as which KB updates one should install (versus which ones to hide), Woody Leonard's site recommends that update descriptions in the Windows Update list that begin with "Security update for Windows ..." should be installed, but those that begin with  "Update for Windows ..." should NOT be installed. In other words, install the KB updates that are for security and do not install the others (i.e., non-security).

I would also recommend to keep updating GWX Control Panel regularly.

Microsoft's updates for Office 365 are totally separate from Windows Update.  Most of your questions are answered in my previous posts.

I understand microsoft now broke the "security only" rule -- the latest security update for internet explorer also at least pushes Win10.

You can't even trust them for the security updates.  Just like congressional bills, it's only security update [plus annoyware or other stuff pushing/forcing Win10].
