If it's a PC, just grab another drive and install Linux now. Swear to god, you'll naturally and very quickly just not boot to Windows again. It's like...
Day 1: Install Ubuntu. Drive around, do stuff, learn.
Day 3: Install a different distro like Mint or whatever. Drive it around.
Day 5: Install the one you ended up liking most. All these installs take like 10 mins top btw, so go nuts.
Day 10: You havent used Windows except maybe for your work's 365 stuff. All you games, programs, etc. are on Linux now.
Day 14: Wipe the drive Windows is on and reinstall it on a shrunk partition. Only install your stuff for work or just leave it default.
And that's it. Yourself free, but it's still there if ever have to use it for something. You'll groan when you do though. And if you do WFH with work 365 stuff, the best part of the day is logging off and booting back into Linux. It's like the relief of coming home from work but you've been home all day.
