UnauthorizedAccessException on new ControlChannelTrigger on Windows 10 9926 RRS feed

  • Question

  • Hi,
    Since I upgrade to Windows 10 build 9926 I'm experiencing some trouble with my application.

    When I try to register a ControlChannelTrigger I get HRESULT: 0x80070005 (E_ACCESSDENIED).

    On Windows 8.1 It was functioning as expected, is the ControlChannelTrigger to be deprecated in Win10?

    What kind of verification can I do (some on Package.appxmanifest)?

    Thanks, best regards.

  • Hi,

    Do you set your application as a Lock Screen app in System Setting of windows 10 9926? As far as I know, the issue occurs related to person not set the app as a lock screen app. You can see the link below:


    An app with a lock screen presence must declare one of the following types of background tasks:                                                

    • Control Channel (Windows-only)
    • Timer
    • Push Notification

    Note that the app can run background tasks only if the user has placed that app on the lock screen.

    There is no official article indicate that the ControlChannelTrigger cannot used in windows 10. And the The windows 10 is a preview product. If the problem also occurs, you can post the issue by use of Windows Feedback app — you’ll find it in the Start menu.

    Best Wishes!

  • No luck with Windows Feedback app :-( .

    The problem is still here.

    For reference:

    await BackgroundExecutionManager.RequestAccessAsync();
    BackgroundAccessStatus accessStatus = BackgroundExecutionManager.GetAccessStatus();

  • Hi Manuel,

    This is a known issue - ControlChannelTrigger has been returning that E_ACCESSDENIED error since the first public flight of Windows 10 Technical Preview. We are working hard to get this fixed.
