that is the deprecated way :)

Use
http://src.chromium.org/viewvc/chrome/trunk/src/base/win/metro.h?revision=131...

basically if (NULL != GetMetroModule()) or if (!GetMetroModule) is what you
want. 

+bool IsInMetroMode() {
+  const char* kMetroModeEnvVar = "CHROME_METRO_DLL";
+  char buffer[2];
+  if (!::GetEnvironmentVariableA(kMetroModeEnvVar, buffer, arraysize(buffer)))
+    return false;
+  return buffer == std::string("1");
+}
+
+}  // namespace ui
