I feel really stupid to ask , but can I install this on Windows.
IIRC even KDE plasma worked. But these days there are a few KDE apps on the microsoft store or on kde.org.
Even if you could install that on windows (compiling everythong with cygwin?), it wouldn't really be windows, mind you.

No idea if they still work.
