Selling Windows 10 professional OEM activation Codes. Those codes are Retail - guarantee lifetime, not from MSDN account. Codes from MSDN account are not good and may be blocked after a period of time when the account ends.
My Skype: tripatrick (Huan Patrick). Thanks 👍🏻.
I would like to have a vouch.
if you prefer to have a vouch, i can give you a used code of windows 10 Professional OEM to check with Microsoft supporter. (y). then you'll know its property - OEM or MSDN
Anybody can send used code easily. That is not a proof.
