It's not the only thing, although it is a big one. Honestly Windows just feels better to me and works the way I want it to. It might help that I've always used enterprise versions so I've never had to deal with the awful bloatware. The few things I do want to disable are pretty painless to remove through the group policy editor or one of many freeware GUI tweaker programs.
yeah, fair. There is a big learning curve for an entire desktop environment. And that's before you start getting into trying to do super-custom things and replicate exactly what you had on windows.
I've always held that switching to Linux is hardest for the most technical people, because you know how to do everything already - figuring out how to do X in Linux might take you literally hours, or you can just reboot into windows, where you know how to do it and it will take 5 minutes. It's hard to make that investment in learning the new stuff when you just want to get stuff done.
(But IMHO it's well worth it - For >15 years I've always been appalled every time I've used windows about how inflexible and unconfigurable it is. There's a thousand things that I've been doing forever that I'm just so used to, e.g the ability to make any window always on top, or to use my mouse wheel to roll them up so that only the titlebar shows. There's lots of things like that that I use every day without thinking about it, and the lack of those things makes windows extremely frustrating for me)
