Security News > 2022 > January > 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.

The shattering of Windows was first reported by BornCity on Tuesday, as in, on the same day that Microsoft released a mega-dump of 97 security updates in its January 2022 Patch Tuesday update.

This month's batch included the Windows Server 2012 R2 KB5009624 update, the Windows Server 2019 KB5009557 update and the Windows Server 2022 KB5009555 update, all of which are apparently buggy.

Microsoft's Hyper-V, the other chunk of Windows being broken by the Windows Server updates, is a native hypervisor that can create virtual machines on x86-64 systems running Windows.

On Thursday, following the server update brouhaha, BleepingComputer reported that Microsoft has pulled the January Windows Server cumulative updates, which are reportedly no longer accessible via Windows Update.

As of Thursday afternoon the company reportedly hadn't pulled the Windows 10 and Windows 11 cumulative updates that were breaking L2TP VPN connections.
