How do I distinguish between Windows 2008 and Windows Vista using javascript?
<p>I need to detect the SO of the user in a web application (IE only). I am using the function BrowserDetect.OS from javascript, but it returns the same String ("Windows Vista") when called from Windows 2008 and Windows Vista, and I cannot distinguish the user SO. Is there a way to detect this difference?</p>
