[German]Rollup Update KB4489881, which was released for Windows 8.1 and Windows Server 2012 R2 on March 12, 2019, has a bug that triggers BlueScreens. The bug has beend fixed in the preview rollup update.


Update KB4489881 March 12, 2019—KB4489881 (Monthly Rollup) for Windows 8.1 and Windows Server 2012 R2 has been addressed within my blog post Patchday: Updates for Windows 7/8.1/Server (March 12, 2019). The rollup update fixes some issues in Windows.

  • Addresses an issue that may cause users to receive "Error 1309" while installing or uninstalling certain types of MSI and MSP files.
  • Addresses an issue with a virtual memory leak and the depletion of the paged pool with the CMNB tag that cause the server to become unresponsive.
  • Security updates to Internet Explorer, Windows App Platform and Frameworks, Windows Hyper-V, Windows Storage and Filesystems, Windows Fundamentals, Windows Kernel, Windows Server, Windows MSXML, and the Microsoft JET Database Engine.

This update is automatically downloaded and installed by Windows Update, but is also available from the Microsoft Update Catalog. Microsoft only reported a problem with IE 10 during the release. 

There is a BlueScreen problem with this update

The number of Windows 8.1 users visiting my blogs is quite low, so why it is worth to blog about that issue? It's likely that some admins of Windows Server 2012 R2 systems are among my blog readers. And all issues caused by update KB4489881 are hitting also Windows Server 2012 R2. Microsoft has documented a couple of known issues for this update (e.g. WININET.DLL authentication with IE 11, problems with MSXML6 etc.). 

At this post points to another issue, update KB4489881 is causing blue screens. A user reported the BSOD bug here. Woody Leonhard reported here, that Microsoft had added this as a known issue.

After installing this update, devices with a winsock kernel client may receive D1, FC, and other errors. Additionally, systems that run the Skype for Business or Lync Server Edge Transport role may be affected by this issue.

This issue is resolved in  KB4489893.

Update KB4489893 is the March 19, 2019—K Preview of Monthly Rollup for Windows 8.1 and Windows Server 2012 R2. Let's hope that on Tuesday, April 9, 2019, the monthly rollup update contains no bugs and also fixes the BSOD bug and at least some of the other known issues, such as the PXE boot problem.
