Microsoft released Windows 8.1 RTM to MSDN and TechNet subscribers today with built-in Skype. With deeply integrated Skype, you’ll never miss a message. Now, not only will you be able to view your missed calls and instant messages, but you can answer calls directly from your lock screen. And on the Start screen, you’ll be able to choose how you want to respond, whether answer a call with video, audio or decline and send an IM instead.
Skype will automatically move to the side when you select any link in Skype or shared item, enabling you to do more while you chat. You can also snap Skype and adjust the size of the window, so whether you’re watching a show, listening to music, playing a game together or co-editing a document, you can do more while staying connected to those that matter to you.
