There are a lot of programs on your computer that you will never use, and there are a lot of shortcuts to those programs that you will never need.
Delete the shortcuts.
Delete a shortcut, it's an icon with a little white arrow in the bottom left corner.
Are you sure you want to delete the shortcut?
Delete all the shortcuts, but don't delete the Recycle Bin or Internet Explorer because they don't have little white arrows so they're not shortcuts.
This completes deleting shortcuts.
