Does anyone have a ballpark percentage breakdown of Windows versions currently being used out there?

For example, 60% are using Vista, 30% XP etc etc.

We are currently building an installer and we need to know what will give us the most coverage. What we are particularly interested in is the prevalance of .NET versions as our application has a dependency on .NET 3.5 SP1.

I don't know exact numbers, but I am pretty sure XP is the most used one.

This wikipedia articles gives some numbers and claims Windows XP to be 63.53% market share.

Here's a better Wikipedia link: http://en.wikipedia.org/wiki/Usage_share_of_desktop_operating_systems

XP is definitely the most used, since Vista came out with several problems people don't like, but soon Windows 7 will be out which is a refined version of Vista. So that could make a dramatic change.

Windows market share goes in detail of some numbers you can look at.

Interesting... the adoption of Vista is even slower than I thought

Indeed. I might add that w3schools is ranked as one of the top thousand most visited sites on the net according to alexa, so their logs a probably based on enough data to be rather accurate. However, since it's a web development site, there's probably some bias since web developers are probably more likely to use some platforms such as firefox and linux/mac than the average user.

Vista comment by Andomar is my exact reaction

this was nice :)

That graph is excellent! Thank you. Bring on Windows 7.

I would argue that w3schools is a lousy site to pull this information from for the simple reason that only technical users visit it.
Chris Lively
Yep. That's a valid concern. I do however believe that this reflects more on the browser stats than on the OS stats. Granted, w3schools will probably show a higher percentage of linux users, and a higher percentage of firefox users. I don't think that the distribution of windows versions differs that much from normal users, though.

NT                  0.97%
2000                0.28%

Please explain how this is programming-related.

Of course it's programming related. We program for and within operating systems.

this is not a forum.

I asked him to explain how this is programming-related. He did. The question is open. What's the problem?
Michael Myers
@mmyers: i think he problem is because of "Member for today " ;)
SilentGhost
Woah, I didn't realize I had to walk on eggshells around here.
Sherri
I didn't know that the question was already answered by editing the original question.
Sherri
Nah, you don't have to walk on eggshells. It would be nice, though, if you wouldn't use answers to respond to meta-comments. ;)
Michael Myers
Yeah, I noticed the comment functionality, after I did that. Heh.

My own experience , I have changed 3 job in 2 years working for 1000+ people company. They all use XP. Never heard anything about upgrading to Vista plan.

Valve releases their survey statistics. Helps with operating system versions, but not your .NET 3.5 issue.
