Approach is based on this [forum thread](https://forum.qt.io/topic/133002/qt-creator-6-0-1-and-qt-6-2-2-running-on-windows-7/60) but better: many improvements amongst important fallbacks to default Qt 6 behaviour when running on newer Windows.
The only issue noticed is that scalled UI is somewhat too big for 125% scalling option set in Windows 7. Something should be tweaked with dpi settings probably.
