I waited til the absolute last minute to upgrade from Win 10 to 11. I use the machine just for Steam games and in particular the graphics-heavy stuff that came out in the last year or two.

Out of the blue, for months now, there's something causing the Shift key to remain magically stuck, and there's no way to troubleshoot it that I can tell. Everything is off - sticky keys, accessibility settings, all that garbagey Settings-not-Control-Panel that seems to move around all the time. If I mash shift a couple of times it returns to normal - almost as it Sticky Keys WAS active (and again all that stuff is disabled).

What's annoying about Windows is that There's Nowhere to Go to fix problem - nothing is transparent. I can google away and I'll get people also experiencing this and there's no answer.

With Linux and to a limited extent, MacOS, you can use unix tools and logs and playing around, even if it's hard you're empowered. With Windows you're a slave to Google searches.
