Discover OS - navigator object not working

Trying to get a browser's OS w/something other than navigator object

I'm trying to find the Operating System of some mobile browsers. Internet Explorer is very informative, but Mobile Opera is not working well.

I'm getting Windows CE, but I also need the version number.

<!--
document.write('navigator.appVersion: '+ navigator.appVersion);
document.write('<br/>');
document.write('navigator.userAgent: '+ navigator.userAgent);
document.write('<br/>');
document.write('navigator.platform:'+ navigator.platform);
//-->

I get some details, but not the version number of Windows.

navigator.appVersion: 4.0 (compatible; MSIE 6.0; Windows CE; PPC; 480x800) 
navigator.userAgent: Mozilla/4.0 (compatible; MSIE 6.0; Windows CE; PPC; 480x800) Opera 8.60 [en]  
navigator.platform:Windows CE 

Is there any other way to get the Operating System than with the Navigator Object? I have some drivers for mobile phones that I need to install. This gets me close, but doesn't let me know what version of Mobile Windows I am using.

thanks in advance

As far as I'm aware the only real source for OS information is the user-agent, and so you rely on browser manufacturers supplying useful information there.

You might be able to infer further information from plugins installed perhaps, but I doubt you'd achieve very good reliability and I'm not sure it's even possible.

And welcome to webmasterworld, Capital_C :)
