It's the other way round, at least some, if not all, of these screens were in KDE before they were released in Windows. In general, KDE tends to be widely copied. Even macOS has borrowed a lot from KDE.

It has been over 10 years since I stopped being a KDE fanboy and became just a regular fan, but I remember that during my flame-war era, many features from KDE would often appear in Mac OS and Windows and their most popular applications (such as iTunes).

These days I don't care so much, I use KDE and I'm too old to switch.
