It hasn't happened yet, unless you count the Technical Previews.
This caught me off guard on the name... I am by NO means a Minecraft player, or an PC insider.. But when Microsoft spent all that money on Minecraft I thought..”I wonder if they could tie the game to their operating system?”
I had pictured replacing that hints and tips stuff they used to do with the paperclip, with something more Minecraft like, and possibly different themes and designs based on the game...possibly a minigame right on the computer when you buy it...
