This is Qt 6.6.2 backport that runs on Windows 7 (what?). The repository contains patched source files from the qtbase module. This is Qt 6.6.3 backport that runs on Windows 7 (what?). The repository contains patched source files from the qtbase module.
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.
