Remote Desktop

Hi was wondering if there is anyway of adding remote desktop to windows vista
premium as have upgraded from windows mce 2005 which had this function and
vista doesnt unless u have business or ultimate but i bought ome premium
because i use media centre i think having to buy ultimate to get something as
simple as remote desktop is a little tight as mce 2005 had it as it ran on xp
pro. but as my machine is used for media centre i would like to get to it
remotely without havin to upgrade which i have done once or buy a third party
program. Thanks for your help Wayne
