I just read a great article on OEM software, called Buying OEM versions of Windows Vista: the facts. I am sure the data here could be extrapolated to any OEM software.
The basics with OEM versions of Vista are:
- You absolutely can buy OEM versions lawfully.
- There is no difference between OEM and non-OEM versions (EXCEPT):
- It is tied to your motherboard: You cannot move it to a new computer 3 years from now or upgrade your motherboard.
- Once you open the OEM package, you can no longer return it.
