Windows 10 21H1 is a minor update. It will quickly get installed over the existing 2004/20H2 instance, like a monthly cumulative update. The same process could be earlier seen for 1903 -> 1909 update, and again for the 2004 -> 20H2 transition. However, users who come to 21H1 from versions older than 2004 will experience the full feature upgrade procedure. Windows 10 21H1 has the same hardware requirements as Windows 10 20H2. You will find some visible improvements and new features, but overall you can describe the Windows 10 21H1 update as quite a small one. Let's take a look on its changes.
