Ah, sounds like finally on the right track, thanks.
This however is Windows 8 beta (notice the forum) so there is no 'All Programs', etc.. I did find where they hide cmd.exe and ran it as admin. The desktop.ini nested in the \programdata\ is now changed but win8 doesn't seem to have the same directory structure in the \appdata\. I'll give it a reboot and see if just changing the other location was enough. Thanks :-)
