nit: put this typedef inside the MetroDriver class.

+
+// Helper class to manage the metro driver dll. When present in the system,
+// the main process thread needs to call InitMetro(), normal execution of
+// chrome initialization will continue on a second thread while the main
+// thread will be servicing the metro message loop.
+class MetroDriver {
+ public:
+  MetroDriver();

nit: new line after here

+  // returns true if chrome is being launched in metro. If so we should
+  // call RunInMetro(). If not then we should just run chrome as usual.

+  // is closed by the user.
