Zorin OS 9 ~ 32bit; It's a linux distribution and the reason I've got my chromebook running it is because it's immune to Windows Viruses. so I'm safer. and because It's more of an ubuntu feel.
Currently on my main computer I am just running a standard windows 7 but I have 3 laptops and I have fedora on one, Just plain linux on another, and Kali linux on another. Linux is fun to learn and mess around on though that's why I have it on my laptops so I can go around and play
On my desktop:Windows,going to dual boot with a linux distro later,
On laptop:Arch Linux,and Ubuntu
Also I have some usbs with distros on them:Kali Linux,Lubuntu,one with Windows XP,PloP,Elementary OS,Linux Lite,and like 10 other usbs lol
This is kinda old but I use Windows 10 right now, and Kali Linux on a different laptop. I have a desktop and another laptop with Windows 7 home premium.
