I want to get the computer user profile name to put log text on the appData
note: This is just for IE, (currently using this for windows 7 gadget)
The default would be, without profile name is this
C:/Users/user/AppData/Local/sampleFolder/
but when there is a profile name on it, what should it be?
C:/Users/{profileName}/AppData/Local/sampleFolder/
My fixed solution (but I recommend the accepted answer)
function GetComputerName()
{
    try
    {
        var network = new ActiveXObject('WScript.Network');
        // Show a pop up if it works
        alert(network.computerName);
    }
    catch (e) { }
}
