What I have here is a OEM copy of Vista Business 32-Bit. The only difference between the retail and OEM copy of Vista is that with this one you dont get a pretty box, and also you do not get free support, but who uses that anyways.

This is a SP-0 copy, so its the first one to come out, but you can still update it with SP1, 2 and now 3. Looking to get $100obo for it.

Still in the original box, never opened still MS sealed.
