what OS you use?

And here I am, using Windows server as my OS

ios on phone and windows on pc ofc

I've got Windows 10 as my primary partition, but I'm slowly starting to wean myself off of it and start using Ubuntu more frequently. Most everything I need to do is fine on Linux.

I use Mac and Windows, as developer, I choose Mac for the unix underpinings, gaming is windows

Only Windows! Best OC ever!!

Windows and Mac, but I have always preferred Windows.

I was always windows as I thought Mac OS was weird and difficult to navigate but when I went to uni I used a Mac and ive never turned back! doesn't slow down the same was a PC does!

Windows 10 and Ubuntu. Linux for the more server-type stuff, windows for wanting a good UX.

for my pc i use windows 10 pro and for my dedicated servers i use ubuntu

Mostly Ubuntu Linux, next to MacOs. I try to avoid Windows at any cost.
