some questions about Vista Game Explorer

People who use Vista should know it (go to Start Menu and click the Game shortcut), I got some questions for it
1..How does it know a newly installed program is a kind of game and add it to the Game Explorer
2..How does it got the information of the game (such as ESRB , rating score...)
Can I make a thing like this to run in XP ??

i am not sure(because i don't have VISTA) maybe it extract those information from registry and new generation of games provide such information in standard format that VISTA can use them.

Yes, toraj58 is correct.
These are usually games labeled "Games For Windows", these settings that the Game Explorer gets from the registry include :
BoxArt
AppExePath

And are usually stored in the HKEY_LOCAL_MACHINE_\Software\Microsoft\
Windows\CurrentVersion\GAMEUX\ registry key.

You can manually add old - ish games to the Game Explorer as outlined here :

There is also a tool that can be used to achieve this, found here :
