Windows 10 came out almost 10 years ago and they offered a free upgrade to Windows 11. I know people love to hate on Microsoft, but they’ve done better than most technology companies when it comes to security updates here. You’re lucky to get even half of that length of support from most Android devices for example.
My very expensive tower PC can't "up"grade because it doesn't have a TPM 2.0 module. So unless Microsoft plans to give me a new CPU (and new mobo) it's not free for many users.
