As promised by Microsoft full Skype integration came to Windows 10 devices.
In the latest version the Microsoft Messaging app now finally integrates with SMS and Skype messaging, and this means users can seamlessly switch between messaging via SMS or Skype Messages.
A tap of a button will also let you switch to sending Skype Video by opening the Skype Video app, which can also make audio-only calls.
