How to Update Windows 10 to Version 21H1

Most users assume that they'll automatically get Windows 10 version 21H1 as they do other updates via the Windows Update service. However, many have noticed that this feature update is unavailable even to those that already run versions 2004 and 20H2.

One reason why update 21H1 might not be available for your device is if your machine is not compatible with the update. Microsoft has to approve your computer's hardware and software configuration for the update to become available for your PC.

So how can you update Windows 10 to version 21H1 if it's not available through the Windows Update service?

You have two possible ways to get this feature update. You can either:

a) Update Windows using the Windows 10 Update Assistant

b) Update Windows using the Media Creation Tool.
