2026 I've read in multiple places. However, they have done a security update recently for Win 7 which supposedly was out of maintenance some time ago. My computer guy suggests to not worry. I've read several articles including one that stated that a lot of 11 features are already in 10. Also, I don't want to be the test user with multiple fixes and updates for the next year or so that seems to happen with every new OS. I'm good with 10 Pro for a while yet.
