You can drag applications from the Most Used Apps or All Apps lists to the right side of the Start Menu. You can also right-click a specific application and select “Pin to Start Menu.” Once you’ve pinned your tiles, you can drag and group them. You are able to access a text box above the groupings that allows you to rename the groups. You can also right-click individual tiles to resize them or disable the “Live Tile” functionality that may allow for content to change on the face of the tile such as current news and information. Refer to Microsoft’s article for more details and a brief video walkthrough.
