Microsoft revealed this week that it has finalized Windows 10 version 21H1 and will soon begin deploying it to customers. But you don’t have to wait: You can install it right now.
And while early upgrades to some previous versions of Windows 10 can be painful or unreliable, I don’t believe this will be the case with version 21H1: Like versions 1909, 2004, and 20H2 before it, Windows 10 version 21H2 is not “True “Feature update. Instead, it is built on the same code base as 20H2 and is just a small revision with few new features. In addition, if you are already using 2004, it comes as a cumulative update, so the whole process will take less than 30 minutes.
Go to “Settings” (WINKEY + I) and go to “Update & Security> Windows Internal Access”.
Click the Home button. When prompted, select the Microsoft account to use.
Select “Release Preview Channel” and then click the Confirm button. Then click Confirm again and restart your computer when prompted.
When the computer restarts, go to Update & Security> Windows Update and click the Check for Updates button. You will see that “Feature Update to Windows 10, Version 21H1” is available as an installation option. Install all pending updates first. Then click “Download and Install”.
The feature update will be downloaded and installed. If you’re already using Windows 10 version 2004, this process will only take a few minutes, because again, this is not a real feature update. Click Restart now when prompted.
When the computer restarts, you will see that you are already using Windows 10 version 21H1. This can be seen in About Windows (winver) or in Settings> System> About.
Now you need to disable the computer from the Windows Insider program: Open Settings and go to Update and Security> Windows Insider Program Enable the “Stop receiving preview versions” option. You will continue to receive service updates on a regular schedule from now on.
This is ready.
