In July, Microsoft stated that it would "roll out the Preview for Universal Skype experiences built into Messaging, Phone and Video apps on Windows 10" sometime during the summer. Well, summer has now come and gone with no such release, and now Microsoft is no longer offering any timeframe for when those app will be made available..
Windows Central contacted Microsoft to get an update on the Skype apps for Windows 10 and received this response from a company spokesperson:
"We want to make sure Skype built into Windows 10 is the best experience possible, so we're taking some more time to make sure it's ready for users. In the meantime, you can continue to use Skype for Windows desktop, Skype for Windows Phone and Skype for Web on Edge."
While the Windows 10 Skype apps are not ready for the public, leaked versions of the Messaging and Video Skype apps for Windows 10 Mobile were recently released.
