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.
The period after MS stopped messing with it and before software stopped supporting it was the nicest time to use Windows 7, I expect it to be the same for Windows 10.
