what OS you use?

Windows and I also have Lubuntu installed on a partition.

i use windows , never have i ever used another os other than like Phoenix OS

Windows since the beginning of time

Windows by default i guess

macOS Big Sur, been using Macs exclusively since Tiger. Windows before that.

Windows on the everyday desktop machine, Linux on everything else

I use Windows 10 and besides Linux with Manjaro KDE

I am using Windows and Centos =)

PoP!,Kali,Win10 + some random os

I have worked on all operating systems pretty extensively. All of them have their short comings but I think Windows offers the most functionality and ease of use for power users. File management is very good on Windows as well as device support. As a creator and gamer, I could never use another platform as my primary platform aside from Windows. Let's hope Windows 11 is better than 10!
