Nit: Please rename this the metro restart service or something metro specific.
Also, is there any reason this is a class? It could equally by a namespace.

Done.
class-style felt a bit more 'natural' for grouping the functions together, and
matching up the filename + classname. But I'm not really a fan of the
creating-a-class-just-with-static-functions model either. I'll try out a
namespace to see how it looks.

+ public:
+  static void HandleStartupForProfile(Profile* profile);
+  static void SetAppLaunchOnStartupForProfile(Profile* profile,
+                                              const std::string& extension_id);
+
+ private:
+  DISALLOW_COPY_AND_ASSIGN(AppLaunchOnRestartServiceWin);
+};
+
+}  // namespace apps
+
+#endif  // APPS_APP_LAUNCH_ON_RESTART_SERVICE_WIN_H_
