Windows 10 will reach end of support on October 14, 2025. The current version, 22H2, will be the final version of Windows 10, and all editions will remain in support with monthly security update releases through that date. Existing LTSC releases will continue to receive updates beyond that date based on their specific lifecycles.
Assuming I still have my current job at that time, this is really going to suck for me. I have an old virtual PC runnning Windows 10 that I use once in a while to maintain some shitty old software. It was a giant PITA setting it up. I regularly back it up because of that.
Hopefully I can just continue using it, but I'll need to disconnect it from the internet somehow. Will still need some limited LAN access. I guess it will require some strict firewall rules. I know just enough about networking to muddle through...maybe.
