Here I am listing some tips to manage your tiles which will help you to get the most of Windows Start Screen.
1] You can use mouse wheel to scroll left to right or right to left through your tiles.
2] To move a tile, simply click and hold then drag into the group you would like to see it, once you have placed it where you want, just release.
3] Any Desktop shortcut or program can be pinned to the Start screen by right-clicking the icon and choosing Pin to Start
4] In the bottom right-hand corner of the start screen is a magnifying glass with tiles, click this icon to get a zoomed out view of your Start screen. In this view, if you right-click on a group of tiles you'll be given the option to name group, which can be useful if you have a group of related tiles, you can also click and drag a group to organize your tile groups.
5] Resize any User tile or Live tile by right-clicking the tile and choosing resize.
6] If there is a tile you want on your Taskbar, right-click the tile and choose Pin to taskbar.
7] Show admin applications on the Start screen by clicking Settings in Charms (an opaque sidebar that appears on right side of the screen shortcut key: Window key + C ), click Settings, and change the Show administrative tools from No to Yes.
