I'm working on some projects right now related to quasi-retrocomputing stuff and Windows is the target for some of them for a few reasons. The Windows kernel still offers some some nice API's that linux either doesn't have anymore or is in the slow process of gutting. Plus whe shopping for specialized hardware, I'm often stuck with linux kernel 2.x drivers, and while I doubt the equivlent Windows drivers have been updated since then, I have more faith that they can run unchanged. Plus WSL offers me enough of what I'm missing for now. Also, admittedly I'm just more familiar with it.

Also my GPU does not play well on Linux. Games have performed much worse under Proton or even natively on Linux than they do on Windows.

Eventually I'd like to start trying some OS's outside the Unix-like and Windows family though. I've had my fill of Linux, Windows and *BSD.
