The dev tooling on Windows for things that aren't .NET has gotten much, much better in the last 10 years. Sometime in the last 4 years I stopped feeling like I had to have a Linux installation available to switch for my programming needs, and I've mostly just been using WSL instead. I still keep the Linux installation around, but now it's months in between when I boot it up.
