   7 // This tool can register and unregister a given exe as a potential default

  11 // TODO(robertshield): By default, this creates a run-time dependency on
  12 // chrome.exe since it's the only thing we have right now that works as a
  13 // default viewer process. Investigate extracting the metro init code and
  14 // building them into a standalone viewer process.
