I'm looking at stopping the popup to upgrade Windows future versions from showing up on my network computers, but I do not see the update to add this to my Server 2012 domain GP? I see for 2012 R2, but not just 2012. Anyone know if this is available in this version or just need to manually install an update? My 2008 servers are getting the KB3065988 update just fine.

I don't know if you're using WSUS but this update caused all of my 2012 R2 servers to stop responding back to WSUS. As far as I could tell it might have still gotten the updates because the logs showed they were still checking for updates.

I would not install this update on 2012 R2.
