Key notes

  • Microsoft has reinstated problematic January 2022 Patch Tuesday updates for Windows Server.
  • The updates had compatibility issues with several bugs and users had made several complaints.
  • Now, Microsoft has restored the updates after fixing them.
October Patch Tuesday updates

On Jan. 13, Microsoft temporarily halted Windows Update from delivering faulty updates to its customers. These patches had been listed in the company’s catalog but were not delivered to users via Windows Update.

The severe bugs caused by those Windows Server patches left users with no choice but to disable the updates. Thankfully, Microsoft quickly fixed the issues, so the updates are available once more.

In a move that may have been a mistake, Microsoft removed the problematic updates for Windows Server on Tuesday.

Microsoft is yet to acknowledge the issue

While the company hasn’t acknowledged the issue publicly, it’s clear that these Patch Tuesday releases for Windows Server are causing problems.

An email from Microsoft to Bleeping Computer acknowledging the flaws, and that they are currently investigating them. The problems are now also listed in the known issues of the Windows Message Center.

After installing KB5009557 on domain controllers (DCs), affected versions of Windows Servers might restart unexpectedly. Note: On Windows Server 2016 and later, you are more likely to be affected when DCs are using Shadow Principals in Enhanced Security Admin Environment (ESAE) or environments with Privileged Identity Management (PIM).

Severe bugs in the updates

Some users are reporting bugs in certain Microsoft Windows Server updates. These bugs include problems with domain controllers rebooting, ReFS volumes disappearing, and Hyper-V functionality issues. Microsoft received reports of these issues while delivering this month’s January 2022 Patch Tuesday updates to Windows Server.

If you use Windows Server, it’s worth holding off on this month’s Patch Tuesday until Microsoft fixes the problems. But by doing so, you keep open vulnerabilities the patches were meant to eliminate. 

Of course, this is an issue that frequently crops up in Microsoft’s patch cycle. Every few months, there’s another major service malfunction caused by a Windows update so sit tight.
