Which operating system do you use?
I’m still using XP Pro until MS stop supporting XP at 2014 and by that time the OS might be W9 or W10, I prefer to hand on to XP as long as you can until MS say they will stop supporting it sooner or until 2014.
7, XP, Linux, FreeBSD… (cannot vote with only one option available, this poll needs fixing for nerds like me :P)
Similar problem here. 
(XP/7/Linux - even an old W95)
But I’ll vote for XP, as it’s the one in my sig.
xp pro
Same here. But I use win 7 too much, so voted for that. XP goes for testing etc. Linux for malware related stuff
Windows 7 and XP Pro.
The XP Pro system is so slow compared to my Windows 7 system. 
Windows 7 64 bit desktop, windows 7 32 bit on 2 laptops.
Windows 7 64 and loving it 
Windows 7 32bit actually.
I also have Win ME in another computer but is broken.
Not really a fan of Polls, but many people have more than one OS and this only gives the opportunity to vote for one.
Do you have any particular interest on opening this poll?

Windows 7 and I like it very much!
Mixed OS
WinXP/7/Linux
No.
Windows 7x64 SP1…it’s a state law in Texas!
Of course it is, but put XP on the machine that now has 7 and see how much faster everything is.
No way Windows 7 Upgrade Advisor said forget about it!

What do you know as you are still running Vista Home Basic SP2 :
The upgrade advisor has nothing to do with it. Of course it will tell you to run 7 because you can. XP will run faster than Windows 7 on any computer. It’s just a fact of life. When XP was the new thing, you could put 98SE on a machine that came with XP and it would blaze. It’s just a matter of the better hardware in the newer machine. As computers get faster and more capable, programmers find ways to use all that extra power and leave you with a machine that really doesn’t do things any faster than the older ones did with the simpler OS. If you would put XP Pro on that better machine, it would be faster than W7. I have no doubts whatsoever about it.
Windows 7 64 bit.
