You could access the Windows registry:

var registry =
  Components.classes["@mozilla.org/windows-registry-key;1"].
  createInstance(Components.interfaces.nsIWindowsRegKey);
registry.open(registry.ROOT_KEY_LOCAL_MACHINE,
             "Software\\Microsoft\\Windows NT\\CurrentVersion",
             registry.ACCESS_READ);
var systemRoot = registry.readStringValue("SystemRoot");
registry.close();
