[windows software] windows 8 > windows 7 downgrade rights

[sted]

anyone know how easy/hard it is if you buy a pc/laptop that comes with 8 pro to get the 7 pro downgrade serial key?

got a school wanting 42 laptops there is a good deal on some that have win8 pro but that school dosent have ees licensing so i cant just quickly shove on 7 enterprise

 

dont really fancy 10min phone call per laptop
