 // 7- Windows calls CommandExecuteImpl::Execute()
 //    Here we call GetLaunchMode() which returns the cached answer
 //    computed at step 5c. which can be:
 //    a) ECHUIM_DESKTOP then we call LaunchDesktopChrome() that calls
 //       ::CreateProcess and we exit at this point even on failure.
 //    b) else we call one of the IApplicationActivationManager activation
 //       functions depending on the parameters passed in step 4.
 //    c) If the activation returns E_APPLICATION_NOT_REGISTERED, then we fall
 //       back to launching chrome on the desktop via LaunchDestopChrome().  Note
 //       that this case can lead to strange behavior, because at this point we
-//       have pre-launched the browser with --silent-launch --viewer-connect.
+//       have pre-launched the browser with:
+//       --silent-launch --connect-to-metro-viewer.
 //       E_APPLICATION_NOT_REGISTERED is always returned if Chrome is not the
 //       default browser (this case will have already been checked for by
 //       GetLaunchMode() and AHE_DESKTOP returned), but we don't know if it can
 //       be returned for other reasons.
 //
 // Note that if a command line --force-xxx is present we write that launch mode
 // in the registry so next time the logic reaches 5c-ii it will use the same
 // mode again.
