Security News > 2022 > January > Admins report Hyper-V and domain controller issues after first Patch Tuesday of 2022

Microsoft's first Patch Tuesday of 2022 has, for some folk, broken Hyper-V and sent domain controllers into boot loops.
As well as the broken Hyper-V, popular tech blog Born City noted problems with boot loops on domain controllers, with other versions of Windows Server affected.
As for the updates, a common thread appears to be an Active Directory fix, although a TITSUP* hypervisor and boot loop problems are not listed as known issues for any.
Still, if you're running Windows Server 2012 R2, you might not have much longer to worry about Microsoft breaking things.
While uninstalling the patches appears to resolve the issues for those affected, the patches also contain important security fixes.
The Register asked Microsoft if it was aware of the problems and planned to issue further fixes.
