In terms of OEM and retail licenses, if we purchased an IT suite, and then purchased retail windows licenses to cover that IT suite of PCs, does that then cover us for the future so that if those PCs were replaced, we wouldn't need to buy an additional license for the new PCs? Am I right in thinking that I would only need to buy an additional license if the PCs were initially purchased with OEM licenses (ignoring the whole EU ruling stuff that is)?
So if I had 550 retail licenses sat in a drawer, the whole school would be covered for that many PCs permanently?
Whereas if I had 550 OEM licenses, I would have to buy a new one every time I replaced a PC?
Do I have that right?
