Press the button in the lower-right corner, and you’ll have access to the other options, including resize, live tile, pin/unpin from taskbar, and uninstall (available under “more options”). In the top-right corner, you can unpin the tile. In the following example, we see a large, static tile which has been long-pressed (such as if you’re using a touchscreen) to reveal touch controls. You can turn off live tiles, which will convert them to a static tile. Live tiles might be cool to some, but to many of the rest of us they’re just a flashy animated distraction. Here we see the difference (from the previous screenshot) between wide and large. Some tiles may not have all those sizes available. Your choices are (usually) small, medium, wide, and large. You can also resize tiles to better fit within your scheme. In addition to pinning to Start, you can pin or unpin from the taskbar, and uninstall the app.
If you want to pin or repin an app then click or tap the “All apps” button, long-press or right-click the app you want, and select “Pin to Start”.
