Windows 11 is out, but Microsoft isn’t abandoning Windows 10 just yet. The November Update for Windows 10 (also known as version 21H2) has been rolled out to Windows Insiders in the Release Preview channel and is also available for download as an ISO file. Microsoft expects the current build, version 19044.1288, to be the same that will be released to the general public next month.
As milestone updates go, Windows 10 21H2 includes few user-visible improvements. One notable addition is support for the WPA3 Hash-to-Element (H2E) standard, a more “computationally efficient” addition to WPA3 that protects against side channel attacks (see the Wi-Fi Alliance PDF here). Another is GPU compute support for the Windows subsystem for Linux.
Microsoft has not said whether the 21H2 update will be the last major maintenance update for Windows 10 now that Windows 11 is here. We do know that Microsoft will eventually bring the new Microsoft Store from Windows 11 to Windows 10, and the older OS will continue to receive updates for Microsoft Edge and (presumably) other built-in apps that get their updates through the Microsoft Store.
We also know that Microsoft still offers the typical 18 months of support for the Home and Pro versions of Windows 10 21H2, which doesn’t bring us close to the end of Windows 10 update support in October 2025. It seems so probably we haven’t seen the last of Windows 10 yet.
Despite the release of Windows 11, Windows 10 will remain relevant for years to come due to the relatively high system requirements of the new operating system; Windows 10 will be the last version of Windows to support most PCs made before 2017 or 2018. Installing Windows 11 on officially unsupported PCs is possible, at least for now, but Microsoft has reserved the right to shut down security updates for those PCs at any time. time and for any reason.
