I suspect it's related...
Yesterday, I did an update of the virus definitions for Microsoft Defender (settle down, I have two Win 10 machines in a household with a LAN and 3 M$ systems and 4 Linux systems along with various Android/IOS fondleslabs) on my Windows 10 Pro machine and got a message telling me I had to activate Windows.
I fixed it by reentering the internally stored product.key. What a pain in the ass.
