Skype for Windows 8 updated in the 1.6 release: stake around Contact blocking

Henceforth available,this update, aims to give a ‘’higher’’ control over who can contact you by adding the ability to block contacts. Therefore to block a contact, select the person’s name to open up the chat window. Bring up the command bar by swiping at the top or bottom of your screen (or right click), and select block. In addition you may also choose whether you want to remove or report the contact request as spam. Finally we have
improved loading speed and reliability across the application.  This means that as a result, contacts load speed should now be a lot faster.
