Before you submit your app for certification and listing in the Windows Store, use the Windows App Certification Kit to test your app and make sure it's ready to go.
The Windows SDK includes the Windows App Certification Kit. You can use it to test your app for the Windows Store (for Windows 8.1 and Windows 8), and for the Windows 7, Windows 8, and Windows 8.1 Desktop App Certification Programs. Learn more about the Windows SDK for Windows 8.1.
To test your app on Windows RT, download the separate Windows App Certification Kit for Windows RT.
Note: To run Windows App Certification Kit on a Windows RT PC, the kits policy needs to be installed. For details on installing the kits policy, see ARM Kit Policy Installation.
