do these programs work ok on windows 11?

i am using classic shell version 4.3.1 (Classic Shell: Downloads) and sledgehammer version 2.7.2 (Download Sledgehammer - MajorGeeks) on windows 10

i want to ask is there anyone using those programs on windows 11? if yes then is everything ok and there are no issues?

I can say about Classic Start Menu 4.3.1: it works in Windows 11 without noticeable problem. So, if you use Windows 10 and perform in-place upgrade, it should work well too. However, I suggest to replace it with Open Shell because development of Classic Shell stopped long before Windows 11.
