The registry and Windows+O hotkey work at the system level, tweaking a user setting. Applications aren't supposed to mess with it. There is an application-level way to set autorotation preferences, and once the user closes your app or switches to a different one, then their existing settings (or the other app's) take over.

MSDN has a good example of using the relevant APIs here: https://code.msdn.microsoft.com/windowsapps/Auto-Rotation-Preferences-87ae2902

If your app has only one autorotation preference that it keeps throughout its lifetime, then it is simplest to just set it in your manifest. There are a few options there that you don't get with the APIs such as supporting both landscape and landscape flipped.
