As my point of view Window Xp is a best operating system because it is easy to understand and use. Easy to install in computer.It supports all feature and functionality.User can be easily use this kind of os.

Windows XP was the best until Windows 7. Even UAC was the only thing, it would still be worth upgrading to Windows 7.

Now I use Windows 7 on all my PCs.

I use WinXP, Windows 7, Ubuntu (Linux), Mac OS, iOS 5 (iPad)

But I really love Ubuntu...

Archlinux master race here. Everything installs so incredibly easily and quickly. The only thing I can't figure out is Ruby on Rails. That's got to be the toughest thing I've ever tried to install.

I'm Use Windows XP and Windows & mostly.

Windows 3.1

Seriously, we've pretty much got them all here but the majority of all the girls uses XP and Seamonkey as our main browser.

I would say 99% of all designing is done on XP. well, my hubby, brother in law and two nieces use Win 2000 pro for Autocad and refuses to upgrade past Windows 2000 or Autocad past 2004. I think they all use Autocad2000 99% of the time.

Must be a man and niece thingy.

I am using windows7. I have also used windows xp in past.

Earlier i was using Windows XP , now i am using windows 7.

Hello all of you, I am using window7, before that I was using window xp. Both are having good features.

hi all,
I'm using windows 7. Its very nice to use.

Me too using Windows 7.. Superb to use and I love it a Lot.. Thanks to Microsoft

At my office window 8 and in my home it's window 7.

I am using Window 7 operating system from a couple of years and it is running extremely well. It is user friendly and its features and functions are really impressive. People should use this operating system for having a great pc experience.

Most the time I use Windows 7. Only sometimes I use Ubuntu for some special operations!

On my two home PC's I use Win7 x64 and on my work laptop Win7 32bit. In future, maybe, will try Win8 but not sure.

Just replaced Vista with Windows 7...

Windows 7 64-bit

Windows 7 Ultimate 32bit. I must say there's a huge difference between Win 7 Home and Pro/Ultimate editions.

I actually hated Win 7 until I got the Ultimate edition. In fact, I think XP Home was better than Win 7 Home.

One more thing - if you're buying any Windows OS get the 64bit. Its the best way to go because its backwards compatible for almost all apps, tools & programs whereas if you have a machine that was built for 64bit capabilities and a 32bit OS is installed then some features in some programs will not work and your OS will run a little slower

Currently I am using Window 7 but I am thinking to upgrade to Window 8 in next 2-3 months.
