First of all you need to know that there is the ability to change your icon grid on the programs and settings screens from 3 to 4 columns. The simple registry edits needed are as follows:
In HKLM\Software\Microsoft\Shell\
Add a New Key “IconConfig”
In there Add DWORD Value:
“HorizontalIconSpacing” Dec value=”112?
“VerticalIconSpacing” Dec value=”115?
“IconTitleFontSize” Dec value=”6?
If you don’t want to edit your registry than you can simply install this cab made by XDA-Team.
By decreasing “HorizontalIconSpacing” to 90 5-rows of icons can be achieved, but that may be pushing things a bit. On larger screen devices this mod will be even more useful.
