In Internet Explorer, use:
alert(navigator.cpuClass); // CPU info
alert(navigator.platform); // Operating System

The navigator's oscpu attribute is throwing undefined on XP IE7 and WIN7 IE9 machines. Other attributes such as platform
etc work fine.
alert(navigator.oscpu);
I want to know how Javascript can identify the version of windows (Windows Xp, 7 or 8)
Can someone help?
EDIT:
Got the answer
navigator.appVersion
return something like this...
4.0 (compatible; MSIE 7.0; MSBrowserIE7; Windows NT 5.1; .NET CLR 1.0.3705; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; MS-RTC LM 8; .NET4.0C; .NET4.0E; dmx:m; mty:p; slx:mi.by.as; ssx:NonCitrix)
So in this
Windows NT 5.1 means Windows XP. If it was Windows NT 6.1 it would mean Windows 7 & If it was Windows NT 6.2 it would mean Windows 8 etc.
Hope this helps...
