Security News > 2023 > November > Windows Server 2022 update gave ESXi host VMs the blue screen blues

Something likely to be absent from Microsoft's Ignite event is talk of a fix rolled out to deal with malfunctioning Windows Server 2022 Virtual Machines following a problematic update from the company.

The culprit was the KB5031364 October update, which contained a variety of fixes and updates for Windows Server 2022, from changing the spelling of Ukraine's capital from Kiev to Kyiv to addressing issues with the Server Message Block service.

Regarding the original problem, Microsoft said: "After installing this update on virtual machines running on VMware ESXi hosts, Windows 2022 might fail to start up. Affected VMs will receive an error with a blue screen and Stop code : PNP DETECTED FATAL ERROR.".

It's barely a year since Microsoft broke Hyper-V. In that instance, the issue was so severe that an emergency fix had to be pushed out to give administrators the merriest of Christmases.

Then there was that time earlier this year when Microsoft inadvertently broke VMs running on VMware ESXi hosts.

While we applaud the fix turning up in the November release, Microsoft issuing updates that break key functionality should give administrators pause for thought.
