I still use Windows 7 to this day, I have so many memories with it, it feels special. Really like how customizable it is, I just get a really good feeling from it. I used Windows XP when I was growing up too and it's one of my favorites, I still have the that computer and it's right next to me, I've still been taking care of it, I have so many memories with it. It used to be in the living room back then and I remember using it a lot. I really like Windows 8/8.1 too, had a touchscreen computer with it back then. Windows 7's my favorite of all time, I really like the look of Vista too, the launch was terrible but it got better over time. Windows XP has a special place in me
