I’ve just installed fresh Windows 7 from MSDN. Then I trid to activate it with serial code also from MSDN.
But the activate failed with status code: 0x80072F8F.
I checked few more things in the system and realised that not only activation is failing, but also Windows Update and even Microsoft web pages are not working correctly. Instead they are reporting certificate issue.
It looks to me that Windows 7 cannot handle certificates correctly, and therefore it cannot update or activate itself.
On MS comuniti I found suggestion that installing those updates should help:
KB4474419 – SHA-2 code signing support update for Windows Server 2008 R2, Windows 7, and Windows Server 2008: September 23, 2019
KB4490628 – Servicing stack update for Windows 7 SP1 and Windows Server 2008 R2 SP1: March 12, 2019
But it didin’t.
So, does anyone tried to install Win 7 recently and had similar issue>
