Windows 10 but I do most of my work in an ubuntu 22.04 VM in virtualbox. But use windows for games and casual use.
Server runs ubuntu 20.04 server which has a bunch of services for my network and my main storage.
Laptop runs ubuntu 22.04 desktop. It’s an old laptop so I’m using ubuntu to extend its life.
Can always run a linux distro with a windows VM in virtualbox to access those softwares when you need them.
I do the exact opposite rn but my plan is to switch them… whenever I get around to it…
