Privately using dwm [1] for many years now and never looked back.

But having to working under a MS Windows 10 setup now, I was wondering:

Is there anything equivalent for MS Windows?

I used bug.n for a while

It worked pretty well but was occasionally buggy, but that's the best that can be expected without replacing the Explorer Shell. I'd recommend trying it out.
