Q. I see products like Windows 8.1 Professional—COA only—advertised for sale. Is this legal?
A. Offers to distribute parts of the OEM system builder software packages are not legal. Under no circumstances are system builders or any other vendors authorized to distribute single OEM system builder software components such as stand-alone Certificates of Authenticity (COAs).
Please note that the Certificate of Authenticity included with each OEM system builder software package authenticates only the software components with which it is legally distributed. As mentioned, any offer to distribute parts of the Microsoft software package (such as the COA only) is not authorized, and any individual who were to obtain parts of the Microsoft software components would not be authorized to use the associated software or redistribute the components. For OEM system builder Windows desktop operating systems, the complete software package must include the COA, hologram CD, and manual(s).
