In our Tile Locker post, we saw that the Windows 8 Start Screen Tile database files that contain the tile locations, layout and states are stored in the following files:

%LocalAppData%\Microsoft\Windows\appsFolder.itemda ta-ms

So if you wish to have the same start screen customizations for all the users, copy the appsFolder.itemdata-ms and place it into the following location:

C:\Users\Default\AppData\Local\Microsoft\Windows



Make the file Read Only.

This way all the users on a computer will have the same start screen customization.

Lets me know if this works/doesn't work for you!
