Windows 10: Windows 11 Pro product key showing as invalid

I recently bought Windows 11 Pro from Walmart. I upgraded my CPU from a Ryzen 5 to a Ryzen 7 in order to meet the system requirements. After doing this, I tried activating Windows 11 and it says the product key is invalid. I know I have never activated it before and I only got it approximately 3-4 weeks ago. It also came with a thumb drive but I am unsure how to use it to install the software. Any idea why my product key would be showing invalid?

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.

 

Why my production key invalid?

why my product key is invalid, i had tried another code in google (KMS), also invalid. I am sure my windows is original since this included with the laptop. FYI my windows type always changing. Now my windows is 11 pro education, later can be 11 pro, later can be 11 pro N, and so on. I dont know what happen, this is new laptop.

 

Invalid product key Win 7 PRO

A few years ago after purchasing Win 7 Pro. When it came time to activate it. I called they gave me a product key that I am using now (not the product key that came with the CD) I have been using it installed on the same computer for at least five years. Now I am getting messages that the product key is invalid and to call and activate. The product key given is an OEM product key. So I called today and was told yes, the product key received from MICROSOFT is in fact invalid and since the support for Windows 7 has ended they cannot help me even though I have a valid product key with the win 7 Pro CD i purchased 5 years ago. I tried to use the CD's product key to update the system, but it rejects the key. Any ideas?
