r/sysadmin on Reddit: Microsoft Extending Server 2012 Support
November 15, 2023 -
It would seem that microsoft has decided to extend support for 2012 another 3 years. Well at least we got some old stuff migrated that management might not have given the budget for in any other case.

r/DefenderATP on Reddit: When extended support ends for 2012R2 does that also mean MS Defender will no longer be updated?
June 11, 2023 -
I've been asked to test onboarding of W2K12 R2 which seems like a waste of time since I realize extended support for 2012 R2 ends on 10/10/23. In order to support my argument against spending my time performing this task I'm seeking definitive clarification whether or not when extended support ends if that also means that 2012 R2 will no longer receive MS Defender related updates? I assume "security updates" includes Defender, but I would appreciate it if someone can point me to a KB that explicitly says that support for Defender is also ending, or that Defender updates are included in "security updates." Thanks in advance.

Historically I've seen critical vulnerabilities patched even outside support windows. However, msft staff isn't going to let you use their standard support path for direct support. You maybe able to purchase extended support and effectively create another support path to provide it. F/e I worked for a state government, and they have very old systems on extremely expired platforms. At that agency we purchased extended support licensing for sql 2003 I think. We hired an IBM DB3 exclusive contractor for ongoing operational support. (There are very few humans left that do this) So there are likely options to keep a legacy system running. I'd present those type of options unless running unsupported is a small risk scope.
