Microsoft's Windows 10 November 2021 Update is now live, which is apparently not the final version of this operating system! If the last few Windows 10 feature updates are any hint, it might take over 6 months for some users to receive this latest version of Windows 10. Don't want to wait that long? You can manually download and install Windows 10 November 2021 Update on your compatible PCs.

The official rollout of the Windows 10 November 2021 Update may take over several months to finish, even though it's a pretty stable upgrade considering version 21H2 is an incremental update. However, you should note that there could still be some issues that remain to be resolved.
