What this means, for us, is that you can buy a machine with the cheapest Windows 7 edition, format the hard disk, and afterwards you can grab yourself a DVD of Windows 7 Ultimate to install it.
Then you just have to install the digital certificate issued to your manufacturer (they are very easy to find on the forums) and .. voila! your Windows 7 Ultimate edition will pass the authentication and validation procedures with flying colors......
I know that royalty oem XP install media are indeed different. You can install such an XP on any non-royalty oem machine but it won't activate and MS won't activate it when you try the phone method.
Installing a standard XP on a royalty oem motherboard will behave exactly like any other motherboard:It will still ask you to enter a key and activate it (unless you're using a corporate version of pro ofcourse).
I also once got hold of an old Fujitsu-Siemens P3 motherboard which had a licence for 2k. I installed a FS XP Home on it and it worked (that motherboard was sold with a system that let you pick wether you wanted 2k or XP btw).
Anyway, for your windows 7 trick, you'll still need a Royalty oem motherboard?
