Instructions to upgrade to Windows 10 Sun Valley (21H2)

Microsoft revealed this week that it has completed Windows 10 Sun Valley version 21H1 and will soon begin releasing it to users. If you want to immediately upgrade Windows 10 version 21H1, without waiting, follow the instructions below.

Windows 10’s May 2021 Update, also known as 21H1, began rolling out in the Preview channel on April 28, 2021. Like the 20H2 update, this is an update. Small update focused on security improvements and fixes. Major features originally planned for 21H1 have been delayed to 21H2 by the end of 2021.

You can see this paragraph for the latest changes to Windows 10 Insider build 19043,928 which Microsoft announced as the final build on April 28, 2021.

Upgrading some versions of Windows 10 early may encounter many new errors, but I do not believe that version 21H1 will have such a case. Like versions 1909, 2004 and 20H2 before it, Windows 10 version 21H1 is not a “real” feature update. Instead, it is built on the same code base of 20H2 and is just a minor version with a few new features. Plus, if you’re already using 2004, it will be distributed as a cumulative update, so the whole process should take less than 30 minutes.

Summary of new features in Windows 10 21H1

To recap, here are the new features in 21H1 in addition to general bug fixes, security, remote access, and quality updates:

• Support Windows Hello multicamera to set up external and internal cameras in Laptop using Windows Hello.
• Windows Defender Application Guard performance improvements include optimizing document opening times.
• Windows Management Instrumentation (WMI) Group Policy Service (GPSVC) updates improve performance to support remote work scenarios.
