Just like I said I would post it in the blog, here is the location that you can find the iTunesPrefs.XML to edit for both Windows Vista and XP.
C:\Documents and Settings\username\Application Data\Apple Computer\iTunes or
C:\Documents and Settings\username\Local Settings\Application Data\Apple Computer\iTunes
If you can't see the file, make sure that your hidden files are set to be visible in Windows Explorer.
There ya go!
