First OS, WinXP.

Later when win7 was discontinued, I kept windows 10 on my desktop and Ubuntu on my laptop. It wasnt until Valve started working on proton and most of the games I play became playable on Linux that I ditched windows entirely.

I distrohopped around for a while, but always found myself landing back on Ubuntu, so it's what I've stuck with to this day, although if anyone else asks me what distro they should get, I will usually recommend mint.

Microsoft Extended BASIC

Le menu.

The first one my family owned, was Windows 95.

Not sure if the first one I used was Windows 3.x, DOS, or MacOS

First OS was DOS, though my parents used a computer with Windows 3.1 on it before we got the dos box.

Excluding Damn Small Linux, first real Linux was Mandrake 9.2 (download edition).

Of course Ubuntu was my first Linux distribution. I didn't use it for long.

First OS: DOS 4.something on dad's PCXT clone.

First Linux: Kurumin Linux

First OS: I think it was Windows 98. I have then gone through XP, Vista, 7 and staying at 10 for as long as i can.

First Linux distro: Ubuntu 10.04 or 10.10 don't remember clearly but it certainly was before GNOME 3 and in a VM. From then i have also run Fedora, Debian and most recently Linux Mint and Pop! OS in VMs as well. Maybe one day i finally set up a dual boot...
