Windows 10 - Unhook "tel://" association

When I click a link starting with tel: Windows automatically opens Skype. Does anyone know a way to force it to open the app selector dialog again? To be clear, I don't want to just associate a different app. I want to be prompted to select an app when I click the link.

Solution 1:

Try the following:

1. Open Registry Editor.
2. Goto HKEY_CLASSES_ROOT\callto\shell\open\command.
3. Delete the Key Value.
4. Do the same to HKEY_CURRENT_USERS\Software\Classes\callto\shell\open\command.
5. Goto HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\tel and remove the value of Key ProgId.
6. Restart Computer.

Edit: Included one more key.
