I tried to get the windows user name in IE browser only using the below code.

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

How to get the windows username in other browsers like chrome, mozilla, safari.

    Uhm. I'm surprised you can do this in IE! This is incredibly intrusive and shouldn't be done. I'm pretty sure that _privacy conscious_ browsers like Chrome and Safari dont do that. They also dont support ActiveX. Thank god. – somethinghere Mar 24 '15 at 12:06

I Agree with Eric comment. However try following hacks. Most likely to work in win7

In IE 

var objUserInfo = new ActiveXObject("WScript.network");
document.write(objUserInfo.ComputerName+"<br>"); 
document.write(objUserInfo.UserDomain+"<br>"); 
document.write(objUserInfo.UserName+"<br>");  
var uname =  objUserInfo.UserName;
alert(uname);

Firefox:

function getUser() {
   return Components
     .classes["@mozilla.org/process/environment;1"]
     .getService(Components.interfaces.nsIEnvironment)
     .get('USERNAME');
}

    The JavaScript you have posted for Firefox is only valid in a legacy extension. It isn't valid in a normal webpage. Including it here is inappropriate. – Makyen Oct 07 '17 at 06:44

As of today it is impossible, and will most likely be in the future as well.

The only quirk I can come up with; is to run a custom Java-Applet that checks it for you. However this is a passive action, and thus, you can not automatically extract it without the clients permission.

    But, just to add, even using an applet shouldn't really be done. If you have to ask for user permission anyway, just ask the user to type in their name in a dialog or something. Otherwise this privacy disaster should be avoided. – somethinghere Mar 24 '15 at 12:12
