Microsoft Yanks Buggy Windows Server Updates

Microsoft has yanked the Windows Server updates it issued on Patch Tuesday after admins found that the updates had critical bugs that break three things: They trigger spontaneous boot loops on Windows servers that act as domain controllers, break Hyper-V and render ReFS volume systems unavailable.

It can hit all Windows Server versions that act as domain controllers, according to my estimation.” Domain controllers are servers that handle security authentication requests within a Windows domain.
