What os are you using?

Windows 10 and some linux on my servers also some windows server 2012 and 2016 Smile

Manjaro with KDE here. I can run like 90% of the stuff I need, or just use WINE in some cases (navicat, league, etc).

If I need to run a specific app (for example, mobaxterm, or whatever else that only works on windows) i'll just spin up a VM in seconds.

Using windows 10. Easy platform for customizing and all stuff.

Windows 10 as 90% of people xD
But I think that on the most used Microsoft OS I would put Windows 7 in second position because good Windows 8/8.1...

You clearly didn't mention the proper details.

Well mine is Windows 10 too but I am on LTSC 2019, without any bloated stuff. I always update to the latest as soon as it's available.

I use Windows 10 pro beacause it has the support of Active Directory and i love to play with that !

I use many system. For daily work i use windows 10 but for developing i use linux debian.

Pirated Windows 10. Please don't take me to jail.
I have tried using Linux before, it never was more than a novelty to me.

I've been using win7 for long but now im using win10

Windows 10, as always! I used to use Mac OS but got really bored of it.
