Windows 10: A recent Microsoft update cause my Windows 11 Education Pro Upgrade to no longer be activated.

Following a recent Microsoft update, Windows 11 Education Pro Upgrade is no longer activated. The error message states:We can't activate Windows on this device because you don't have a valid digital license or a product key. If you think you do have a valid license or key, select Troubleshoot below. Error code: 0xC004C003.I have tried the Troubleshooter and still will not activate.The upgrades were done two years ago and I can no longer find the activation codes to re-enter to reactivate.I have the product Id and the last 5 digits of the 25 digit product key.How can I retrieve my product codes

Windows 11 Education Activation

Hi, where can I get a windows 11 education activation key? My system is currently running on the Microsoft Windows 11 Education OS, however I recently purchased a new SSD and I need to reinstall my version of windows on the new SSD but I don't have the USB installation or an activation key

 

Windows 10 Education Pro

I've not had an opportunity to test Pro Education edition yet but I am running normal Education on a Hyper-V virtual machine and on dual boot with Pro on a laptop. Basically Education is exactly as Enterprise, meant for domain or Azure AD use. Main differences when compared to Pro are missing Cortana and no possibility to use Microsoft account as initial user account when setting up Windows, although when selecting initial user as local domain user a normal local account will be created which can then be switched to a Microsoft account instead of joining a domain.

Native Windows apps in Windows 10 Education edition are the same than in Pro edition, Cortana being the only exception.

If you already have setup Windows 10 Pro on your machines with a customised image I can see no benefits in doing the job again deploying an almost similar OS. This is of course only my personal subjective opinion based on what I know at the moment; I have no knowledge or insight about what additional features (see highlighted part in quote below) Pro Education might be and if they would be reason enough to upgrade to Pro Education.

On the Microsoft Store for education, there is a section that lists benefits. in the benefits there is a windows 10 pro EDU upgrade feature. How can I get a windows 11 version of this? if I cannot, how can I go about using our Institutions shape the future program to get discounted windows 11 education or pro licenses?
