Microsoft pulls problematic Windows updates that break Hyper-V and more

Microsoft headquarters

Problems with updates are hardly a new phenomenon for Microsoft, but 2022 has not got off to a good start. Not only were the KB5009543 and KB5009566 updates found to break VPN connections, another trio of updates has now been pulled because it contains critical bugs.

The KB5009624, KB5009557 and KB5009555 updates have been withdrawn because they are causing Hyper-V to stop working. The problematic updates have also be found to cause domain controller reboots and to render ReFS volume systems inaccessible.

All three updates relate to different versions of Windows Server; KB5009624 is for Windows Server 2012 R2, KB5009557 is for Windows Server 2019, and KB5009555 is for Windows Server 2022.

The fact that the updates are for Windows Server will come as a relief for millions of home users, but it is more of a headache for system administrators around the world.

For now, Microsoft has not acknowledged that the updates have been pulled, but there are reports from sysadmins who say that the updates are not being offered automatically at the moment. Tests performed by Bleeping Computer show that Windows Server 2019 is no longer being offered the KB5009557 update.

The updates remain available from the Microsoft Update Catalog, but it would be a good idea to avoid manual installations until Microsoft confirms what is going on.
