Hi Prayag,
Unless MS has something specially arranged for this in IE/EDGE that I don't know of, it's impossible to get this data from withing the browsers sandbox. Browser vendors went to extreme length to prevent this (and any other kind) off access to system resources. Google for browser sandbox if you want more detailed information.
This is a security measure. We don't want that to be changed. Think about it, do you want a browser that makes private system resources available on the internet?
Regards
Sander
