Uh - No.. It's not the process, it's the company. Microsoft has a history of starting something only to lock in customers and then changing everything so they can bleed them for every penny they have. Or, if they cannot, then just dumping the technology and leaving all their customers high and dry.. Again..(Playforsure anyone?)

But who will trust MS and their complex EULA that could in fact mean the opposite of what you expect.
And their ongoing statements like 'we do not collect private or identifiable info' and then they proceed to tell you they collect MAC and HD serial numbers and such, which is not only strongly linked to a person's computer but half the time in electronic salesrecords with CC number and name and address of the purchaser.
So in that light their view of privacy might not be ours.
