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).
