Q:

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.

A:

Try the following:

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

Edit: Included one more key.
