Steps to reproduce

With a Win 11 "director" (where security key is set) and a Win 10 "client" (where director's security key is used to connect)...

On the Win 10 client (moused over from the Win 11 director), whenever I do anything that triggers the UAC Yes/No popup, either this blocks MWB (cursor sent back and stuck on Win 11 director) or I can't click Yes or No on the popup. I have to hard switch to the Win 10 client to click Yes/No on the popup.

✔️ Expected Behavior

I was expecting that UAC popping up would have absolutely no impact on whether MWB would continue working.

❌ Actual Behavior

(see Steps to reproduce)

For controlling those sort of prompts, you have to use the service mode. This can be enabled from the Settings. It's basically that MWB needs extra permissions to be able to do stuff that's restricted on the computer, like UAC prompts.

Per #26147 I won't be able to do that.

this also no real fix, cause in service mode an UAC Promt forces a reconnect and throws the pointer back to the host
