As part of the April 2021 Patch Tuesday update, Microsoft releases the update KB5001330 for devices running Windows 10 20H2, 2004, and 21H1 with several fixes and improvements.

According to the Microsoft support site, the update KB5001330 bumps the version number to build 19041.928 and 19042.928 for version 2004 and 20H2, and it addresses four specific problems.

Update KB5001330 for Windows 10 20H2 and 2004

Microsoft has announced KB5001330 on the Windows support site. If you are already running the Windows 10 October 2020 Update or May 2020 Update, this update will address these problems:

  • Addresses an issue in which a principal in a trusted MIT realm fails to obtain a Kerberos service ticket from Active Directory domain controllers (DC). 
  • Fixes a problem with security vulnerabilities identified by a security researcher. Because of these security vulnerabilities, this and all future Windows updates will no longer contain the RemoteFX vGPU feature. 
  • Addresses a potential elevation of privilege vulnerability in the way Azure Active Directory web sign-in allows arbitrary browsing from the third-party endpoints used for federated authentication.
  • Security updates to Windows App Platform and Frameworks, Windows Apps, Windows Input and Composition, Windows Office Media, Windows Fundamentals, Windows Cryptography, the Windows AI Platform, Windows Kernel, Windows Virtualization, and Windows Media.

You can download the updates to install them manually for versions 20H2 and 2004 from the Microsoft Update Catalog website.

The same fixes are also available for version 1909, but as build 18363.1500 (KB5001337). Also, as a reminder, this release will reach the end of support on May 11, 2021, for computers running the Windows 10 Home, Pro, Pro for Workstation, and Server SAC editions. If you are still in this release, it’s recommended to upgrade to the latest version.

Windows 10 version 1809 is also receiving the exact changes, but as update KB5001342 (17763.1879). Similar to version 1909, this release will no longer be supported starting May 11, as such, it is recommended to upgrade to the most recent version (see above link).
