Live tiles can show up to 5 different pieces of content in a single update. These are queued up and cycled through on a schedule that the developer does NOT control. However, updates to the live tiles are controlled by the developer in three ways:
- The application, while running, can update the tiles
- The tiles, periodically, can refresh themselves from a URL
- A background task can update tiles no more frequently than every 15 minutes
- A cloud service can push updates no more than 500 times a day
The user can disable the "live" part of a tile. However, the behavior of the tile if "live" cannot be otherwise controlled. And in many ways, even the developer is limited in his ability to control them.
I think your English was just fine.
