Security News > 2022 > January > Microsoft brings back January 2022 Windows Server updates
The January 2022 Windows Server cumulative updates are once again available via Windows Update after being pulled yesterday without an official reason from Microsoft.
After Windows admins installed the updates, some found that it caused their Windows Servers to go into boot loops, ReFS volumes to become inaccessible, and Hyper-V not to start.
After the numerous problems, Windows admins told BleepingComputer, and our own tests showed, Windows Update no longer offered the new Windows Server updates.
When we asked Microsoft why they pulled the updates from Windows Update, we were only told that "Microsoft is aware and investigating the issue."
Starting today, the Windows Server updates are available via Windows Update once again without any reason from Microsoft why they initially pulled them.
For Windows Server 2012 R2, Microsoft also created a new known issue for the Hyper-V problems, stating it is affecting devices using UEFI. Microsoft says they are investigating both issues and will release a fix in a future update.
