Windows 11 Home to Pro upgrade failed with 0x80070490

As two error codes occur in the same time, one is Win 11 Home update with the install error 0x80070002 & one is Win 11 Pro upgrade failed with the error code 0x80070490.

Should I fix Win 11 Home update with the install error 0x80070002 first and then fix Win 11 Pro upgrade failed with the error code 0x80070490?

 

Windows 11 Home to Pro upgrade failed with 0x80070490

Hi,

I purchased a brand new Acer laptop with Windows 11 Home edition preinstalled on it. After activating the Windows and installing all the available updates, I purchased a Windows 11 Pro licence through Microsoft Store, but the upgrade failed with Error Code 0x80070490.

I searched the net and found a very similar question at Windows 11 Home to Pro upgrade failed with 0x80070490 and then - Microsoft Community I went through the suggested solutions, but it did not work for me.

There was no Product Key for the Windows 11 Home edition that came with my laptop and it says my Windows has been activated with a digital licence linked to my account. There is no way to change the Product Key on that activation page, except for the option to upgrade Windows, and change the product key. I tried the generic Product Key that was given in the above link, and again I got an error message with the same error code: 0x80070490.

Since I received no product key when I purchased the Windows 11 Pro licence, I am not able to enter the correct product key to see if that's the cause of this message.

Can anybody help me, please?

Fred
