Bluetooth 'Add Devices' Not Working

From the bottom right Quick Settings panel Bluetooth can be toggled on and off but the ">" button to "Add Devices" does not work with the following error:

 

Faulting application name: ShellHost.exe, version: 10.0.26100.8521, time stamp: 0x10ff34dc

Faulting module name: Windows.UI.Xaml.dll, version: 10.0.26100.8521, time stamp: 0xe70b2ca6

 

This happens when the Device Flow Service (DevicesFlowUserSvc) is not running.  If the Device Flow Service is disabled it will cause this error and pairing will not be available using Quick Settings in explorer bottom right or in immersive control panel systemsettings.exe.

 

Also Device Association Service and Device Association Broker are required for the Bluetooth pairing to function properly.

 

 

 

  • The sfc /scannow is not usually a good solution for OS configuration.

    In this case the Device Flow Service is needed to use the Bluetooth settings menu.  Enabling the service will solve the problem

  • Hello,

     

    Suggest you to run System File Checker scan:

     

    1. Search for 'command prompt' using Windows Search.

     

    1. From results, right click on Command Prompt and select Run as administrator.

     

    1. Type sfc /scannow command and press Enter key.

     

    1. Let the command complete and then reboot the machine.

     

    If that doesn't works, try these steps:

     

    1. Search for 'windows powershell' using Windows Search.

     

    1. From results, choose Windows PowerShell and select Run as administrator.

     

    1. Then type/paste following and press Enter key:

     

    Repair-WindowsImage -Online -RestoreHealth

     

    1. Let the command complete, restart your system then.

     

    Let us know if this helps!
