How to Change the Number of Apps Tile Rows on "Start" Screen in Windows 8

Information
This will show you how to increase or reduce the number of default apps rows of tiles that are displayed on your Start screen in Windows 8.

Note
By default, Windows 8 automatically detects what your current
screen resolution is, and then automatically sets how many rows will be for the apps and other
pinned items on the Metro Start screen based on the screen resolution size. This is usually only
3 to 5 rows by default. For example: If you have a
1920 x 1080 (horizontal x vertical) screen resolution, then you would have
6 rows by default. You could either reduce the number of rows to a minimum of
1 row, or increase it up to a maximum of
6 rows for this screen resolution size.
See table under step 6 in OPTION THREE below for more on this.
EXAMPLE: Apps Rows Set from 5 to 6 on Start Screen
NOTE: This is with a 1900 x 1080 screen resolution.



OPTION ONE
