IDK...... all I see this type of a system doing is, reducing piracy, giving a share of money from every software company to MS (Royalty), and going more into a bully kind of a company. With it allowing only certain programs to be installed on the forthcoming OS.
It doesn't sound too good if it sticks only to this kind of policy. The 5 separate computer installation is like a multi user license, doesn't make too much sense either for a person who owns just one rig and needs to pay the royalties for the other 4 rigs he's never going to own.
Really, MS does seem to be going bananas..... or should I say Apple.
