Ok we have all heard about VISTA RETAIL and OEM versions right, right. 
OEM you can only install on Machine A, when you try and install it on machine B it wont let you.
But how can they do this?
XP
You install XP on one machine ok fine.
Then you try and install it on another machine and you have 30days to do this right.
So you try and activate it with the same code and it wont work so you just ring up Microsoft and say you had to fromat your machine they give you a new code, job done.
Is VISTA diffrent?
