How to Restore Windows 8.x Start Screen to the Default Tiles

After a while your Start screen can became a bit messy and you might want to reset it to it's default...

The information about the Windows 8 Start Screen is saved in a database in the user's profile folder:

• %LocalAppData%\Microsoft\Windows\appsFolder.itemdata-ms 
• %LocalAppData%\Microsoft\Windows\appsFolder.itemdata-ms.bak (the backup file).

Simply delete those two files or run the next two commands in Command Prompt (Start >> Run >>cmd):

• del %LocalAppData%\Microsoft\Windows\appsFolder.itemdata-ms [ENTER]
• del %LocalAppData%\Microsoft\Windows\appsFolder.itemdata-ms.bak [ENTER].

Restart or sign out and back again and your tiles are ready to be messed up again. :)
