Windows 10: Unable to upgrade from 11 Home to 11 Pro on a brand-new laptop

I just purchased a new laptop from Amazon. I also bought a windows 11 pro key from Amazon. When i go to settings -> system -> activation and enter the product key, it refuses to upgrade. It gives me the error code 0xc0ea000a, which says I changed the hardware on my laptop, but that's not true. It's brand new and I haven't done any type of hardware changes. I updated everything from the Microsoft store and also the Windows updates. I've registered the laptop with my email, I'm the admin on my laptop, I've restarted the laptop many times, I'm just at my wits end. Please help!

Unable to upgrade Windows 11 Home to 11 Pro

Thanks much, Dave, indeed it was a big job.

Clean install of Windows 11 from a bootable USB helped to Activate the Pro.

Just to summarize what was done:

1. Took backup of the drives and save some on cloud.
   
2. Installed the Media creation tool app as you suggested (https://www.microsoft.com/software-...t=Windows 11 Installation-,Media,-If you want)
   
3. Connected the USB and ran the application and downloaded the Windows 11.
   
   1. additional thing which I had to do is to install WLAN driver to the USB in advance, to have the WIFI option available as it was required to connect to a network to download the latest windows features while reinstalling the Windows, and Wi-Fi option was not available.
      
4. Turned off the 'Secure boot' from the BIOS menu.
   
5. Changed the 'Boot Order' in the BIOS menu to first use the USB Boot.
   
6. Saved and Exit, which triggered Restart and Windows installation.
   
7. During the network connecting stage to install the latest updates and features - 'Let's Connect you to a network', I opened the CMD (Shift + F10) and ran than WLAN driver exe to install it and then I was able to connect to my WIFI network.
   
   1. Optional to this step is to BYPASS the network connection stage by following this - bypass "lets connect you to a network" - Microsoft Community
      
   2. Then, doing that manually once Windows has been installed.
      
8. Once everything is set-up, I followed the suggestion from this again, and it worked - Unable to upgrade Windows 11 Home to 11 Pro - Microsoft Community
   

 

Transfer Windows 11 Pro upgrade to new laptop?

I upgraded from Windows 11 Home to Pro on a laptop purchased last year. I've replaced that laptop - is there a way to move the 11 Pro upgrade to the new laptop before I sell the old one?

 

Windows 11 Home to Pro upgrade

Want to upgrade 11 Home to 11 Pro. Tried download, but apparently files transferred were for 11 Enterprise. This will not activate; error is "invalid digital license or product key". This is on a new Surface. How to proceed?

Can withdraw/delete this. The suggestion to downgrade - listed below - with a 'fake' windows 10 key works.
