Windows 10 Home to Pro upgrade problem

I bought a new PC with Windows 10 Home and after making sure it was up to date I went to Settings/Update/Activation/Microsoft Store and purchased the Windows 10 Pro upgrade. I clicked Install on the Microsoft Store window and when done I got the following error. "We can't activate Windows on this device because you don't have a valid digital license or product key. If you think you do have a valid license or key, select Troubleshoot below. Error code: 0xC004C003"

I clicked on Troubleshoot and it couldn't solve the problem and said to contact support for help which was no help as it just referenced a bunch of articles.

One thing I noticed is it shows Windows 10 Enterprise as the version. I purchased the Windows 10 Pro upgrade. I didn't know there was an Enterprise version and it wasn't listed on the upgrade page.

Any suggestions?

 

Can't upgrade from Windows 10 Home to Pro

Hi Bill,

Thank you for posting your query in Microsoft Community. We apologize for the inconvenience caused and will assist you in the best possible ways.

I suggest you to download and create an installation media for Windows 10 Pro form the link provided below:

Download Windows 10

After the installation media is created, suggest you to upgrade to Windows 10 Pro from the installation media. When the upgrade asks for product key, enter the product key purchased for Windows 10 Pro. If it does not accept, suggest you to skip the activation
step. After the Operating System is installed, suggest you to activate by phone by following the steps below:

• Press “Windows key + R” and type “slui 4” and press Enter.
• Select the Region from the list and click Next.
• Call the Toll-Free number provided on top and can activate via phone.

Hope this helps. Keep us posted on the status for further assistance.

 

Windows 10 Pro is not getting activated after re-install. I purchased Windows 10 Pro upgrade through Microsoft Store.

• Microsoft Tech Support Team tried the Default Pro key. It upgraded to Windows 10 Pro but didn't get activated and then they tried "Repair" and that also didn't work.
• I performed a clean install with "ei.cfg" like you suggested (mine is OEM). Still not working.
