Well the one that keeps me needing a Windows machine for on… Ableton Live + VST plug-ins.

Musicbrains Picard is also the best metadata autotag app I’ve used.

“Reclaim Windows” type powershell scripts, feel like group policy and powershell are underutilized by average desktop users. A lot of the things people complain about with windows you can control with it. Primarily a debain user myself but I need Windows to run Ableton on custom hardware so it is what it is.
