ConfigMgr 1910 Hotfix KB4538166 – Client Update for version 1910

A new hotfix KB4538166 is available for ConfigMgr version 1910. The update is essentially client update for Configuration Manager current branch, version 1910.

This out-of-band update is applicable only to early update and globally available installations of SCCM 1910 that are installed by using one of the following package GUIDs.

  • 0BB82139-0DC3-4B18-B219-97FB2EFD9E56
  • E2F7B2F9-4828-4650-9144-5DC7956781B7
  • 4CE24C49-E6B0-4B4F-9AD8-CA31FF269F23

In addition to that, this update is also applicable to the following package GUID’s and update KB4535819 applied:

  • 3B4824FF-02FC-40B8-95AB-2AE986B0B63F
  • D237809A-6210-4209-A0E6-247543C241E4

To verify which build is installed, add the Package GUID column to details pane of the Updates and Servicing node in the console. To know how to find the package GUID of SCCM update, read this post.

Most of all the hotfix KB4538166 resolves the following three issues.

  • After updating to ConfigMgr 1910, sites that have deployed a Windows Defender Application Control policy are unable to assign trust to new applications.
  • Feature Updates for Windows 10 version 1903 and higher do not install as expected after updating to Configuration Manager 1910.
  • If your site uses automatic client upgrade, when you update the site to version 1910, all clients immediately upgrade after the site updates successfully. This issue was also addressed with release of ConfigMgr 1910 Hotfix KB4538488. Therefore the following resolution does not apply to the revised globally available build of Configuration Manager 1910, released on January 17, 2020. Because that build already incorporates this specific fix.

Most of all this update replaces the hotfix KB4538488 – clients immediately upgrade after updating to Configuration Manager 1910.
