Dear PC Owner:
Support for Windows 10 ended on October 14, and as we have been warning you for the past several years, this system doesn’t meet the minimum hardware requirements for Windows 11. So, no more security updates for you, unless you pay for extended support!
We are serious about this!
Okay, we let you have those, but that was absolutely the last time!
Or not.
Sincerely,
Your friends at Microsoft
P.S. Without support, you are accepting the risks associated with using this PC. Which you are doing anyway, even with support.
