My gaming PC used to be dual boot but I reinstalled CachyOS from scratch clearing the EFS partition bc it was getting messy from all the distrohopping. I haven't even had a reason to fix my Windows partition lately thanks to Proton.
That said, my work has heavily standardized offoce automation on Windows going on. Can't even really run WSL with that. Hopefully there will be 2nd Gen support for Linux machines in Hyper-V at some point so I can at least do dev work on Linux but that's unlikely currently.
