Damn you got me. I am not a big fan of KDE (Currently using Niri) but I can try to use KDE+aerothemeplasma with nixos as a dual boot (I already used to have KDE nix as dualboot until I accidentally removed that disk and ended up using the glorious tool testdisk to save that) so I will try it some day thank you!

There is also anduinos which I think doesn't try to replicate windows 7 but it definitely tries to look at windows 10 perhaps 11 iirc

There's usually an "uncanny valley" feeling to this kind of projects, but damn, this is good.
