Windows kept getting in the way of my productivity (I constantly needed to find workarounds for problems that didn't exist or were much easier to solve on linux, and I couldn't customize the ui to my liking) + it lacked basic things like a tabbed file-manager (before win11) and my hardware was getting slower so I jumped ship.

I started using Linux many moons ago when the LAMP stack was common for web development. (Linux, Apache, Mysql, PHP). But that was only on servers. It's only in the last couple of years I've switched to seriously using Linux on the Desktop. I finally got fed up of Microsoft writing software as if using their OS meant they owned my machine and they could do what they liked with it. So I've switched. While windows still sits on a partition due to a couple of games, I find I'm going months without needing to touch it. I suspect I'll be rid of windows entirely in the near future.

Windows 8 being unusable on my shitty laptop I had back then, IIRC it would bluescreen 9 out of 10 times on startup (this same bug still persisted when eventually Windows 10 came out). I essentially switched to Linux full time after that.

first just messing around with it, then starting selfhosting and then i started to dualboot just for fun, and one day i by mistake nuked my windows installation, so now i'm a full time linux user
