So I still technically use Windows, but only because I need it because of some software for school, but I still use Linux most of the time. It's mainly the small yet super annoying things in Windows that caused me to switch. Like how everything has to automatically try and back up to OneDrive until you dig into the settings and disable it, or how it constantly badgers you to use insert Microsoft product here instead of what you want to use. Plus as a computer science student, and someone who spends a lot of time in the terminal, Powershell and the Windows command line feel so old and incapable compared to the Linux terminal (WSL has helped with some of that, but not all of it.) It's just small issues that cause big issues when you run into them, because it just makes simple things harder to do than they need to be, usually for the sake of pushing their products.
