A MAR csak a szokásos add el százszor projekt része. :)
When is a new Windows operating system license required and when is one not required?
A new Windows license is not required for a refurbished PC that has:
1. The original Certificate of Authenticity (COA) for a Windows operating system affixed to the PC, and
2. The original recovery media or hard-disk based recovery image associated with the PC.
...
A new Windows license is required for a refurbished PC if:
1. The refurbisher did not obtain the original recovery media along with the system to be refurbished or
2. The PC does not have a hard-disk based recovery image.
The refurbisher must purchase a new Windows license in order to provide the purchaser of the refurbished PC with a genuine, licensed version of
Windows on the PC.

Azaz ha eltűnt az "eredeti" telepítő lemez/helyreállítási partició cseszhetik a gépre ragasztott COA-t (a licencel együtt amit igazol :)), jöhet a másik matrica és csak úgy adhatják el. :)
Lehet máshogy is csak az böri.
