The only reason I still have Windows are a few games that don’t work properly on Linux (via Steam Proton) yet.
I will keep Windows 10 until Steam no longer supports it or all my games run well on Linux (I check for that occasionally). IDGAF about no longer getting security updates as I have moved everything except for those few games to Linux years ago.
Let me guess, suicide by 17 gunshots to the back of his head? In his car in a hotel parking lot?
