@LABFE, as
@Porthos mentions, and what I was trying to allude to in my initial posting to you. What you are attempting to do, is not legal.
To refurbish computers on a professional basis (what you are doing), you need the following.
Can use original sticker.
Os needs to be installed.
Original recovery media.
All 3 becomes a complete licence.
In order to sell a computer, with a COA attached, it needs the following.
OS needs to be installed.
Original recovery media
COA.
If it does not have all 3, then it cannot be sold as a refurbished machine.
Also if you are doing this on a professional basis, and your advertising that you sell refurbished machines, you should become a registered MS refurbisher. The cost of the program is zip/nada/free. Questions are easy enough. And it should give you some props over your competition.
I have wrote a couple of stickies

If you have any other questions, don't hesitate to give me a shout.
