Last Tuesday, Microsoft released January 2022 Patch Tuesday update. However, the patch Tuesday update had several bugs including Windows Server DC Bootloops and Hyper-V break.

Now, Microsoft starts rolling out emergency out-of-band (OOB) updates to fix the issues caused due to Patch Tuesday update.

The company said that Microsoft is rolling Out-of-band (OOB) updates today, January 18, 2022, for some certain Windows versions.

The bugs and issues related to the unexpected restart of Windows Server Domain Controllers, VPN connectivity issues, and failure to Mount ReFS formatted removable media have been fixed with the recent update from Microsoft.

Meanwhile, you can check out the Microsoft Update Catalog to download all OOB updates released today while a few of them can be installed via Windows Update as optional.

Below are the updates that are available to download through the Microsoft Update Catalog:

And, optional updates for below mentioned Windows Versions can be installed via Windows Update:

  • Windows 11, version 21H1 (original release): KB5010795
  • Windows Server 2022: KB5010796
  • Windows 10, version 21H2: KB5010793
  • Windows 10, version 21H1: KB5010793
  • Windows 10, version 20H2, Windows Server, version 20H2: KB5010793

  • Windows Server 2008 SP2: KB5010799

As we hinted before the January 2022 Patch Tuesday update was causing issues within several servers running on the latest Windows versions.

Besides the Windows Server DC reboots, Hyper-V service failure, and ReFS volumes mounting issue, Windows admin also reported facing issues with L2TP VPN connections after installing the recent Windows 10 and Windows 11 cumulative updates and faced the error message; “Can’t connect to VPN”.

For those who can’t immediately install OOB updates, they can uninstall the KB5009624, KB5009557, KB5009555, KB5009566, and KB5009543 updates which are causing these issues with an Elevated Command Prompt. They need to type the following commands:

Windows Server 2012 R2: wusa /uninstall /kb:KB5009624 
Windows Server 2019: wusa /uninstall /kb:KB5009557 
Windows Server 2022: wusa /uninstall /kb:KB5009555
Windows 10: wusa /uninstall /kb:5009543
Windows 11: wusa /uninstall /kb:5009566

Note: Removing the Windows updates will remove all the fixes for vulnerabilities patched during the January 2021 Patch Tuesday.
