Windows 10: Upgrade new table to Windows 11 Enterprise causes windows activation issue

I bought a new Microsoft Surface Tablet with Windows 11 Home edition. I upgraded online to Windows 11 Enterprise by paying the $99 on Microsoft.com. The upgrade went through OK. Now the PC says Windows 11 Enterprise edition but it keeps telling me to Activate Windows. When I go to Activate Windows it says Windows cannot be activated because the product key is not validWhat should I do

Windows 11 Home to Windows 11 Enterprise

Hi There,

I bought a laptop which was pre-installed with Windows 11 Home.

Our company received our latest activation keys for Windows 11 Enterprise and I need to upgrade to it.

I am battling to find any info on upgrading from 11 home to 11 Enterprise. Searching around I only found info on how to upgrade to Pro edition and one post suggesting that upgrading from Home to Enterprise requires new installation of Windows 11 Enterprise,

I already have valid and licensed O365, Visual Studio etc. installed and configured and would not want to redo all of it.

Will running changepk.exe with Enterprise product key successfully upgrade to Enterprise?

Will inserting the new product key simply upgrade to Enterprise?

Help on this will be appreciated.

 

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.

 

New Windows Build Breaks QuickBooks Enterprise 11

This does not work. I tried this first. Loaded with every compatibility possibility that was available. There is another issue that is causing the failure. MS has made a change that is breaking Quickbooks Enterprise 11 in the new update as I first stated
above.
