Microsoft has designated version 19043.928 as the “final” version of Update 21H1 for Windows 10. On April 28, in a Windows Insider blog post, this build was named the “May 2021 Update” and updated available to all Release Preview channel participants for download.
Windows 10 21H1 will be a minor update for Windows 10 20H2, which was a minor update for Windows 10 2004. Microsoft may begin the official rollout of 21H1 on May 11, the date of Patch Tuesday.
Microsoft indicates that the “Insiders” of the Beta and Release Preview channels are already on the “new” builds 21H1 since the start of the week, with the release of build 19043.964. In the Release Preview channel, it is possible to get the 21H1 / May 2021 update by proactively searching for it, going to Settings> Update & Security> Windows Update.
Microsoft has made update 21H1 available for commercial validation through the Windows Insider for Business program starting in March. These attendees have been able to test Windows 10 Enterprise and Pro editions of 21H1 since then.
What’s new in version 21H1
As a quick recap, here’s what’s new in 21H1 beyond generic fixes, security, remote access, and quality updates:
- Multi-camera Windows Hello support to set the external camera as the default when both external and internal Windows Hello cameras are present;
- improved Windows Defender Application Guard performance, including optimizing document open scenario times;
- Windows Management Instrumentation (WMI) Group Policy Service (GPSVC) update performance improvement to support remote work scenarios.
Microsoft also released today a new test version (20344) of Windows Server 2022, its upcoming Long Term Servicing Channel (LTSC) server version, with no watermark or expiration date. I asked Microsoft if this is already the final version of Windows Server 2022 – although the company has already indicated that this product will be available to the general public in the second half of 2021. None answer for now.
