Microsoft warns about upgrading from Windows 10 1909 and 20H2 as it approaches EOL

Microsoft has issued a warning today to anyone still running Windows 10 1909 or 20H2. Both versions will reach end-of-service with the May 2022 security updates due on May 10. Their last update will be on this date, and after that, they will be vulnerable to malicious attacks, so it is very important that people upgrade their systems, especially those connected to the Internet.

In typical Windows 10 fashion, Windows Update will automatically launch feature updates for Windows 10 Home and unmanaged business devices if they are within a few months of end of service. While Microsoft really wants users to turn off these builds, they can still choose a convenient time to reboot their device and complete the upgrade.

The latest version of Windows 10 is 21H2, available starting in November. If you're forced to update your system now, you should try to get to 21H2 so you don't have to worry about upgrading again before June 2023.

Microsoft has written a detailed tutorial on upgrading Windows 10 devices to the 21H2 update. You can also upgrade to Windows 11 if your system is capable, and Microsoft has also published a tutorial on making this upgrade - but it's worth noting that not all systems will be able to run Windows 11 due to the new system requirements.
