Solved Rogue keyboard hotkeys

Upgraded to Win 11 yesterday on Dell OPlex 3060 + MS keyboard. Now, if I type "shift m" on any program, instead of a capital M, I get a box opening lower r with "Connect Cable to Cast - your device doesn't support Miracast . . ". Now, to type a capital M in any program, I must: "Caps Lock" - "type m" - then "un-Caps Lock" to continue (which is a great pain). Any ideas (apart from going back to Win 10)?

Sorted! Nothing to do with Win 11 (or 10). Fixed by using high suction vaccum cleaner over the keyboard. Apologies for rogue posting!

Two possibilities, since I've neither seen nor heard of this glitch before: keyboard malfunction or flawed upgrade installation. Can you try your keyboard on another computer and see whether the same thing happens? If it doesn't, I'd try the in-place repair install procedure. It's fast and painless, and this early in the game on 11, you won't have a whole lot of customization to recapture.

No problem. Happens all the time.

You've barely finished typing your call for help when you suddenly discover the solution.

That's not even embarrassing: it's just an everyday occurrence here. Welcome to the forum, and have a good one.

Thank you.

You're welcome, new friend.
