okay so basically I'm running windows 8.1, because windows 10 hasn't convinced me to upgrade yet. I'm trying to figure out how to show 8 rows instead of 6 on my start screen for win 8.1, if that's possible. REGEDIT did nothing. This is what it looks like with 6 rows. I have about 130 tiles like the ones below for movies, games, tv shows, and programs. You can see why I'd like 8 rows rather than 6 even if it makes the tiles a bit smaller...
