Get OS Win 7 username Javascript

Question

Is it possible to get Windows username and PCName with Javascript in browsers IE, Chrome, Firefox, Opera?

Answer 1

No. That sort of information is not exposed to the javascript engine in the browser.

Answer 2

i'd really wish this wouldn't be possible, but sadly it is (or was). i don't know for sure if this still works on Win7 and with current browser-versions, but in the past you could do this...

Internet Explorer

function getUsr() {
   var wshell = new ActiveXObject("WScript.Shell");
   return wshell.ExpandEnvironmentStrings("%USERNAME%");
}
