When Windows reaches end of support, that does not mean that Windows will stop working correctly, it will continue to work normally, the only difference is you would no longer receive updates to the operating system.
Windows 10 reached end of support last October, however, Microsoft realised many people could not upgrade their PC to Windows 11, and they offered people 1 year of free Extended Security updates (ESU) up to October 2026, did you register for the free ESU in the updates section of the Settings app.
