Hi 闫正凯
I understand you have never used those keys, someone may have used those keys before you, I do hope Microsoft can verify those licence keys for you and you can activate your Windows 10 . . .
Hi 闫正凯
Those OEI licence may have been used before, without knowing where those came from it would be hard to decide if the disks and licences are legitimate or if they have been used before
If the licence keys have been used before, because those licences are OEI, they cannot be used again because they are not full retail licence . . .
Hi 闫正凯
An OEI licence is basically a small system builders licence, where did you purchase that licence and what us the exact error you are seeing when you enter the product key for that licence to activate it?
Did you purchase that licence online and if so, was that very much cheaper than the price Microsoft charge for a Pro licence?
