Although all eyes are on Windows 11 these days, Microsoft still supports Windows 10.
According to current support plans, Windows 10 will continue to receive updates until October 2025. So users whose devices do not qualify for the free upgrade to Windows 11 will have four years to decide what to do in Continuity.
Windows 11 as you know will be released in the second half of the year. But the same goes for a new Windows 10 feature update, as Microsoft maintains the original release schedule for the current operating system.
Therefore, the 21H2 version of Windows 10 will be released for all Windows 10 devices, although Microsoft is now focusing more on Windows 11. So it is likely to include some minor improvements and a few new features.
According to Microsoft's current release schedule, the 21H2 version of Windows 10 will be finalized in September or October and then available on Windows 10 devices in October or November.
The 21H2 version of Windows 10 will be available for all devices running Windows 10, and will probably be needed for those who want to upgrade to Windows 11 without a clean installation.
