thewayneJust a minor issue!
From the article: "The bug appears to be tied to Secure Launch, a security feature that uses virtualization-based protections to ensure only trusted components load during boot. On systems with Secure Launch enabled, attempts to shut down, restart, or hibernate after applying the January patches may fail to complete. From the user's perspective, everything looks normal – until the PC keeps running anyway, refusing to be denied life.
Microsoft says that entering the command "shutdown /s /t 0" at the command prompt will, in fact, force your PC to turn off, whether it wants to or not."
It hasn't affected my two Win 11 computers, haven't powered up my laptop in a month, so it hasn't updated. I would expect this will be updated with next month's Patch Tuesday release, but they may release an out of schedule patch to fix it.
Of course, make sure all your documents are saved before issuing that shutdown command or you may risk losing information.
And all computers will shut down when you pull the plug out of the wall or bus strip.
