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.
Only 3% of Windows users are on Windows 7. Compared to 70% on Windows 10. When that number drops significantly, that’s around the time I’d expect Steam to drop. They’ll go where their customers go.
