Pro Tool is not supported on Windows XP Media Center Edition. In fact alot of audio software has problems with this OS. My first suggestion would be not to buy a computer with XPMC on it. I have found a work around.
First right-click on My Computer and click on manage. Go to "services" look for any services running that have Media Center in the description and disable them.
Second, go into your registry (start:run: regedit) and back it up (file:export) then go to the search command (ctrl f) make sure keys, values, and data are checked. Type in ehsched and delete anything having to do with ehsched , ehmsas , and ehrecvr. (to find the next key click f3)
Do the same search for “media” or "media center" if you are uncertain that the file is a "media center" file, then search for the file in google.
After you do this you will notice your computer runs faster.
By doing this you are giving up your Media Center. You may also want disable Windows "auto-update". I found that microsoft tries to restore missing components.
If you have usb drives you hook up, you may find corrupted files in your autoplay. You can correct this by going to
