We can run Windows 11 with both MP v4.4.1 and MP v5.2.1
Trio have tested the HMI simulator 1.30.1.1935 which comes with 4.4.1 and it works OK.
We also tested the HMI simulator 2.1.2.1874 which is with the next upcoming 5.2.2 release and that is also OK.
There were no long boot times or any bad effects from using Windows 11.
