I'm holding out until they force me to upgrade from 10. They've tried probably a half dozen times or so already to have me choose to upgrade but it's been a minute.
I dunno.. I've always used Windows, being annoyed by their requests to update me to the newest version isn't enough to want to learn a new OS or anything.
I'm running 10 LTSC on my main desktop pc and get no nagging to upgrade at all. Tbh the only thing stopping me from switching to Linux is lack of driver support for my simracing wheel (still waiting, thrustmaster...)
