Recently bought a new desktop computer that originally came with windows 10 preinstalled. I attempted to upgrade to windows 10 pro via the app store. After installing windows 10 pro, its saying windows is no longer activated/there is no valid digital license or key/ Error code: 0xC004C003
I looked for the product key in the email receipt, but its not there?

Hi,
Looks like your Windows 10 home is OEM activated.
To upgrade from Windows 10 Home to Windows 10 Pro and activate your device, you'll need a valid product key or a digital license for Windows 10 Pro.
These are 2 editions of Windows and they require different keys to be activated.
For your reference:

Hope above information can help you.

Yes, I have the same problem - can someone help?
Microsoft have not sent the product code they promised. What can I do?
I have the exact same issue.
Was forced to purchase a PC for work purposes (am definite Mac person). Was told I should update to Windows Pro as that is what is needed for my work. Of course, within 1 hr of having this PC there is an issue. What a surprise. How many hours of my time am I going to waste trying to get this sorted out. Un-freaking-believable.
Has anyone tried getting a refund off Microsoft?
I'm going to go back to PC World where I bought the laptop because it seems like choosing their already installed package was a mistake. My laptop tells me it's not an authentic Windows product, which feels like it must be a mistake?
