Hi, please drop, I think UWP has seen its better days. Both Microsoft 
Edge and Office 2019 are now classic Win32 desktop apps.

Also, could you also drop support for UWP in Qt Creator? When I install 
Qt on my Mac I look at the Qt Creator plugin libWinRt.dylib and wonder 
why? Same on Linux, I get libWinRt.so included in Qt Creator, and on 
Windows 7 of course I get winRt4.dll. Neither Wine or Windows 7 will 
never support UWP so that plugin can be tossed even before Qt6 for those 

Happy Easter /Henry
