You will need to check the userAgent property (of the navigator object, I think).

2K is version 5
XP is version 5.1
Vista is version 6

Hi gsinswai, welcome to WebmasterWorld... I guess you could try searching the user agent for "Windows NT 6.0" ...?

if (navigator.userAgent.indexOf("Windows NT 6.0") > -1) { 
 // Windows Vista 
}

So this will detect if the user is on Window Vista?

That's the idea. Take the following user agents for example...

[1] Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.8.0.4) Gecko/20060508 Firefox/1.5.0.4
[2] Opera/9.00 (Windows NT 6.0; U; en)
[3] Mozilla/4.0 (compatible; MSIE 7.0b; Windows NT 6.0)

For FF1.5, Opera9 and IE7b respectively. The presence of "Windows NT 6.0" in each case should indicate Windows Vista.

But beware that user agents can be faked, so it's not 100%, but I don't think there is anything better?!
