Windows 10: Surface Pro 6 asking for product key on Windows 10 Pro

Hello,


On November 1st, I bought a Windows 10 Pro on Microsoft website and installed it in my Surface Pro 6. It works fine for few days until recently, the system asking for the activation. I tried to go to setting>activation>trouble shoot and it doesn't work. Based on Microsoft website, it said that my error is my key is not unique (error code: 0xC004C003). Since I bought the product from Microsoft website (Order: 7720515466), I don't think that the product key is fake. In addition, the email does not show product key of the Windows 10 pro. What I need to do to reactivate the Windows 10 pro or the worse case, how do I reroll back into Windows 10 home?


Best regards,

VC

Windows 10 Surface Pro 2 Product Key

Hello,

I installed the Windows 10 Technical Preview on my Surface Pro 2 a few months back. Upon upgrading to Windows 10, I did a clean install. My device is now asking me for a product key. I have tools to recover the embedded product key for Windows 8.1, but Windows
10 would not accept it. I restored my device back to 8.1, and it is not accepting the embedded product key either. I am now back on Windows 10 and am curious as to how to fix this issue?
