What Operating System do you use?

Linux FTW! :D

Been using it for... like 15 years, lol. Wouldn't change it for anything!

now I'm using windows 7 x64 no problem at all. I don't have any plan to upgrade win 8 .

I have been using windows 7 for 3 years.
I tried windows 8 on my friend's pc and I hate it.It doesn't have even a start button and it's so complex

win7, it works.

I use Windows 8 64bit

windows 7 for me as well op

i use win7

I use windows 8. I would be using windows 7, but the performance improvements are worthwhile to me.

I still use XP SP3. Good enough for me. I'm not a big fan of changes. :)

I use windows 7 and 8.
