As I said earlier - pedantic
They have agreed to the software being used!!!
It is obvious you're not going to be swayed on this argument.
However the point still stands - this isn't about being pedantic, awkward or anything like that.
The point is what a few of us are trying to get over to people is that there is a license agreement with Windows - not reading it is not a defence.
The OEM, Retail, Educational, VL licenses are all different and it usually works on the more you spend on the license the more open it is.
OEM is the cheapest and is good for one machine.
Retail is upto double the cost, however is good for the life of the OS as you can transfer it from machine to machine - so well worth the extra spend.
You also need to realise the difference between physically and legally possible.
As I said in my example before.
Legally I need a driving license to drive a car.
Physically I can drive one without ever having a lesson or owning a license.
One is legal, one isn't.
If you were to phone up Microsoft for activation and tell them all of the information then you would not get a second activation.
You call and say your OEM license was on a machine, you bought a new motherboard and now want to reinstall your OS they would not give you an activation code.
If however you call up and don't give them all of the information, or tell them it is a warranty upgrade or tell them it was due to a HD failure then yes - they will activate it.
However it still isn't a leagal activation, just because MS have activated only means they are agreeing to allow you to use their software under the license agreement that came with it.
Microsoft were going to totally stop OEM sales into the retail market with Vista to basically stop all this.
Everyone would have to buy retail and by default everyone could then move their copy around as much as they like and enjoy the added benefits of Retail licensing over OEM.
Maybe with Windows 7 we will see OEM products out of the retail channels.
