Microsoft pulls new Windows Server updates due to critical bugs

Microsoft has pulled the January Windows Server cumulative updates after critical bugs caused domain controllers to reboot, Hyper-V to not work, and ReFS volume systems to become unavailable.To get more microsoft latest news, you can visit shine news official website.

Tuesday, Microsoft released the January 2022 Patch Tuesday updates for Windows Server that includes numerous security updates and bug fixes.

These updates are KB5009624 for Windows Server 2012 R2, KB5009557 for Windows Server 2019, and KB5009555 for Windows Server 2022.Soon after Microsoft released this week's Windows Server updates, admins who installed them began reporting that they encountered numerous severe issues.

These issues included domain controllers going through an endless reboot loop, ReFS volumes becoming inaccessible and showing as RAW file systems, and Hyper-V no longer starting on servers.Today, BleepingComputer has been told that Microsoft has pulled the January Windows Server updates, and they are no longer accessible via Windows Update.

In tests conducted by BleepingComputer, we can confirm that our Windows Server 2019 install, which has the December cumulative update installed, is no longer offered the January KB5009557 update.We have not independently verified if the other Windows Server updates have been removed but have been told by Windows admins that this is the case.

The updates are still available from the Microsoft Catalog, but BleepingComputer strongly recommends that admins not install the new Windows Server updates at this time.While the updates resolve 97 security vulnerabilities, with some being critical, they are also causing significant disruption on Windows networks.

January's Windows 10 and Windows 11 cumulative updates are also breaking L2TP VPN connections but Microsoft has not pulled those updates at this time.As we stated yesterday, they were still available via the Microsoft Catalog, and admins later told BleepingComputer that they were also available via WSUS.

It is not clear why Microsoft only pulled them from Windows Update and did not respond to our questions about their disappearance.However, Microsoft has confirmed to BleepingComputer via email that they are aware of the issues and are investigating them.Microsoft has also created two new known issues in the Windows Message Center with more information.

"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)," Microsoft explains regarding the domain controller reboots.
