Buying only license illegal?What does Validation needs?

Hello to all users.I am newbie:)
first: Is buying only license illegal? for example I bought Win7Ultimate 32bit retial key from someone(he sent it by mail). Have I done any thing illegal?
I gave the key to another one ( I didn't use it) and now he wants to validate it by mailing microsoft support. He enailed:
"Is my windows geniune? with this key .... "and he copied the report maid by MGADiag.exe
They answered:

and my question is what information should I give to microsoft? Because I bought license from person not any authorized seller or etc.
*the license is activated already.

the key has to come from some dubious route ,microsoft licences do not allow retailers to sell single keys without the software , so i would, in this case, be very wary

agreed JK, but there are so many fake and technet keys floating about that someone will get their fingers burnt for sure

The above applies to retailers. The rules are a bit different for the end user...

Respectfully, the EULA applies to the bearer, who is essentially undesignated but may be a corporation or a physical person - and trading license keys minus disks is an issue which only the license owner (Microsoft) is authorised to engage in.

On eBay Microsoft have a specific appointee, called a VeRO representative, and if they tell eBay to end auctions and NARU (ban) vendors then trust me, eBay will do just that - and mighty fast too.

Send them the 4 bit of information.

But this looking FAKE to me.

My question would be, why did the origional poster buy a retail key and then turn around and sell it to someone else???? No software involved, if it smells like fish it probably is fish.

thank you for involving in this topic.
My condition is sth like Jonathan_King's condition. I bought it for cheap price and exchange the key with other software licenses with someone. So I am not selling it and according to this post:

I am not doing anything illegal( Because I am not selling)

Send them the 4 bit of information.

But this looking FAKE to me.

but I don't have the information.Specially number 3 & 4.

Some one who I am exchanging licenses with him is worried about "time to time validation" as said in email(post 1)- How can he Validate succesfully the windows which after that he can be sure that his Windows is validated?
