I have tried to uninstall KB5012643 from Control Panel/Program and Features, from Advanced Startup/Advanced Options/Uninstall Updates and also using Command Prompt (Admin) “wusa /uninstall /KB:5012643”. None of them has worked. I did get an error code using Command Prompt of 0x800f0905. I’m starting to wonder if I did a Disk Cleanup and did a Windows Update Cleanup. Would this be the cause of not being able to uninstall the update? Is there some other way to uninstall this update?
