Windows 10: Windows 11 Home to Pro upgrade failed with error 0x80070490

Windows 11 Home to Pro upgrade failed with error 0x80070490. Tried chat, which failed including using the generic code as described in other similar posts but get the same error, and rep remote takeover to create local account to install. Got disconnected using instructions given by MS rep and couldn't reconnect. Very frustrating. Paid $106 and nothing to show for it.

Windows 11 Home to Pro upgrade failed with 0x80070490

I am trying to upgrade Windows 11 Home to Windows 11 Pro, but the upgrade failed (0x80070490).

 

Windows 11 Home to Pro upgrade failed with 0x80070490 and then 0xC004C003

Thank you John, entering this generic product code fixed my system too.

I was upgrading a new Win 11 Home PC to Win 11 Pro from the Microsoft store.

During the install I also got the 0x80070490 error. After a reboot I had Windows 11 Enterprise installed and said it was Activated??? The next day Microsoft must have detected their error and deactivated my system. Still showed Win 11 Enterprise.

Tried the suggested generic product code and a few reboots later I still see Win 11 Pro is activated.

Seems too good to be true...

 

Trying to upgrade to Windows Pro 11 (from Home 11) error code 0x80070490

Bought a new computer running Windows Home 10. Updgraded to Windows Home 11, and purchased upgrade to Windows Pro 11. But it's telling me "upgrade failed. Error Code 0x80070490.

I've seen others have used a temporary key to get it to upgrade, but that must be a specific key as the one they used didn't work for me.

Any help would be appreciated.
