What operating system are you using (Windows, mac, linux)?

windows 10 100% for casual use/gaming etc Its just support more stuff then its counterparts

I am using windows 10 , and aiming to use Linux in the future

Im using Windows 10 and Macos for my macbook

I use both Mac OSX and Linux on my personal computers.

I use windows, I don't really see any upsides in anything else. Mac has a nice layout I guess but a lot of programs don't work on it.

windows 10, i dont like it much though its trying to hard to be the best

Windows 10 PRO, because it's compatible with most games and other things.
