Is anyone able to verify this? I purchased Windows 10 through activation and was given an electronic invoice without the product key. Although it has activated my windows, but for future reference I would require a windows product key. However, I haven't been given one yet.
I've called customer service several times, they said I didn't purchase it and would prefer if I contacted the my region's sales office. One also said, the product key is now tagged onto the email you purchased on. Hence, for future activation I should login my Microsoft email to activate my windows when needed.
Anyone? Please share, or advise!
