Windows 8.1 is arriving on October 17th and we have just learned that Skype will be integrated into the operating system. Skype will be the default Windows 8 messaging application. “Now you don?t have to download your favorite app to stay in touch whenever you?re apart. With Windows 8.1, simply tap the Skype Live Tile, log in, and you?re ready to go. This not only means will you be able to reach over 300 million Skype users across every computer, tablet, or phone you use but, also, everyone with a device running Windows 8.1. By simply searching and adding contacts to your People list in Skype ? the people you care about most are right at your fingertips,” said Skype on the company blog.
