Vista Home Premium Upgrade DVD Academic whats version is this?

[Pottsey]

I can get Microsoft Windows Vista Home Premium Upgrade DVD Academic for under £50 but what’s the difference between this and OEM or the full version? There needs to be a good sticky at the the of this forum explaining all the vista versions.

Anyone know is the Academic version both 64-bit and 32-bit? Does it have the same restrictions as OEM?

I work in a school so I can get it with a clear conscience. The big question is this version or the full none upgrade version.
