wrote, xp mode is great option, but u cant play the games in it.
If you have Win 7 Pro then yes you can use XP mode (XP mode is a slightly modified 32-bit version of XP).
It doesn't offer 3-d acceleration though so if you are looking to play old games that won't work. For 3-d acceleration you will need to download Virtual Box and install a valid copy of XP in a new Virtual Machine.http://www.microsoft.com/windows/virtual-pc/download.aspx
