Microsoft launches Windows 10 21H1 Insider Preview (KB4601382) for Beta channel

The long-rumored Windows 10 21H1 version has finally been confirmed by Microsoft, and the company also admitted that this update is a small update and will not have too many new features. At present, this version has begun to be pushed to the Beta channel. If you use the Windows 10 test channel, you should now be able to receive this version.

In terms of functions, there are actually no new features worth paying attention to in this version. The main improvements include security, kernel, remote access, and improved stability. Although there are no new features, it is not a bad thing for users. After all, this is an old version, so there should be a significant improvement in stability.

Changelog

• Windows Hello multi-camera support to allow users to choose an external camera priority when using high end displays with integrated cameras.
• Windows Defender Application Guard performance improvements including optimizing document opening scenario times.
  • Microsoft fixed an issue that causes a one minute or more delay when you open a Microsoft Defender Application Guard (WDAG) Office document. This occurs when you try to open a file using a Universal Naming Convention (UNC) path or Server Message Block (SMB) share link.
  • Microsoft improved Robocopy’s performance when copying files that total over 400 MB in size.
  • Microsoft fixed an issue that causes a WDAG container to use almost 1 GB of memory (working set) when the container is idle.
• Windows Management Instrumentation (WMI) Group Policy Service (GPSVC) updating performance improvement to support remote work scenarios.
  • Microsoft fixed an issue that causes changes that the Active Directory (AD) administrator makes to user or computer group membership to propagate slowly. Although the access token eventually updates, these changes do not appear when the administrator uses gpresult /r or gpresult /h to create a report.

In principle, we do not recommend that you use the Beta version because poor stability and unknown problems may occur, and there are no new features worthy of attention in this version. If you are still interested, you can go to the Windows 10 system update interface, and then click Windows Insider to select the Beta channel. After joining the channel, it will take up to 24 hours to receive the new version. Since this update is only a cumulative update, the update process should be very fast.

After the upgrade is completed, the system version number will be upgraded to Windows 10 21H1 Build 19043.844. Theoretically speaking, the future 20H1/20H2/21H1 updates will be the same.
