Windows 10: 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 activat

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.

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...
