Andyross A recent Windows 11 security update has left some users facing unexpected trouble: their computers refuse to boot. The update in question, KB5058405, was automatically rolled out to devices running Windows 11 versions 23H2 and 22H2. Instead of simply improving security, it has triggered a critical error for a subset of users. https://www.techspot.com/news/108137-windows-11-security-update-leaves-virtual-machines-unable.html
Somewhat-Reticent Why we delay updating until this beta-testing winds down. ( An update is not always an upgrade. ) ( Profiling virtuals? )
takeahike Andyross There’s a patch that fixes it and is available only in the MS Update Catalog here. Support article for the fix here. No need to run the patch unless you had the error when installing KB5058405 on or about 5/13/25.
