Unable to Uninstall Security Update (KB5094128) on Azure Hosted Windows Server 2022 VM
The screenshots show a healthy component store, KB5094128 listed in Installed Updates, and WUSA consistently returning 0x800f0905. KB5094128 is the June 2026 cumulative security update for Windows Server 2022, and not every Windows update package supports removal. Before trying anything else, snapshot or clone the Azure VM. Use DISM /Online /Get-Packages to identify the exact package, then DISM /Online /Get-PackageInfo /PackageName:<name> to inspect its state and release type. If Windows reports the package as permanent or removal remains unsupported, do not delete files from WinSxS or edit CBS registry data; that can leave the image unserviceable. For this proof of concept, deploy a test VM from an approved pre-update image or test a newer cumulative update instead. The software vendor should provide a compatibility fix, because permanently removing a current security update is not a safe production solution.
