In Germany, the purchase, distribution and use of OEM versions is completely legal. In other words, trading of OEM versions even without hardware is legally permitted. The Federal Court ruling allowed the sale of OEM versions and DSP versions without associated hardware. As a result of this ruling, you may install and use this version on any computer. This is documented in the judgment of the Federal Court of Justice of 06.07.2000 - I ZR 244/97, and states: In the judgment of 6 July 2000 ruled the Federal High Court (BGH) that the exhaustion principle can not be undermined by license provisions of the manufacturers (Az I ZR 244/97 - OEM Decision - Judgment in GRUR 2001, 153). At that time Developer complained against the resale of so-called OEM software, which was contractually tied to new hardware at the time of sale, but had been brought into isolation by the intermediate dealer. The lawsuit was dismissed. The BGH stated in its judgment that the retransmission is free due to the exhaustion of the copyright distribution right.
