What Operating Systems do you use?

Presumably, you can add why you chose to use this operating system, and discuss the advantages/disadvantages of using it.

I use Windows 10, and it's REALLY slow on my low memory computer. I once did some programming, and suddenly the explorer application crashed, and I can't do anything other than shutting down!

I'm going to switch to Lubuntu (because it's the most lightweight Ubuntu flavor)

I use windows 10. I love linux too, especially arch (yeah I'm a "btw I use arch") because of how easy it is to use and the documentation. But except for tinkering, I don't really like having to fix things all the time, and I want to be able to play games easily, so I always come back to windows 10.

dual boot. windows 10 + my personal linux distro. Windows for games or documents, and linux for coding, at most of the time.

TempleOS is the best and nobody can change that
