how to determine the OS version using javascript other than navigator.appve rsion??

afaik, JavaScript only reads the browser’s UA string, if that’s a fake (which is not very difficult), you’ll even get wrong results. and because of JavaScript’s sandbox principle (no access to the client OS), you can’t ask the OS directly (despite IE with ActiveX).

Thank you very much..
