Before they had a much simpler approach of selling a single key to the OEM. The OEM would then purchase COAs from MS that they would affix to the case of the computer, and would be used to register and track changes over time and piracy.
This new system sounds like they will get a box of generic stickers instead of COAs, and instead of having a separate licence, activation key, and COA number, there will simply be a single # that is digitally purchased and assigned to the box which will then track the box throughout the life-cycle of the machine. This is perfectly fine for OEMs, and should actually make their jobs a little simpler on the logistics side of inventory and orders, while making the setup side a little harder. For MS this means that it will be much easier to track individual boxes, and their hardware changes over time, and if they get cash hungry then they can crack down on reactivation after upgrades and such (something that up until now they have been fairly generous with).
I really wonder how this will work for refurbishers like the company I work for. We take old computers, and MS gives us an extremely generous discount so that we can put a fresh legal copy of Windows on the machine that is tied to us (instead of the OEM such as Dell, HP, etc.). For some machines we are just putting XP back on them, while other higher-end XP and Vista boxes are getting Win7 instead. I am sure that MS will still have some form of vehicle for us to be able to provide the service that we do, but when win8 boxes start coming our way, I wonder if we will be forced then to re-use the same OS, or if we will be able to 'downgrade' to win7.
Personally I like win8 a lot, but the user base that we work with are quite computer illiterate and have a very difficult time moving from XP to 7 (which is essentially the same thing when it comes to web browsing and program launching). Moving from XP to 8 would be... traumatic at best. But time will tell, and I suppose this is what we have training classes for...
