Windows 10: Windows 11 Pro reverted back to Home

I have a computer that came with Windows 11 Home. It was upgraded by going to the Microsoft store and purchasing the license. The computer worked fine and was joined to the domain. Someone deleted the user account that was used to purchase the license and now the computer has reverted back to Home. How do I get it back to Pro?

Windows 11 Pro Upgrade from Windows 10 Pro Edition

No but after it installed the malfunctioning Windows 11 upgrade it was listed as Windows 11 Pro. Microsoft Windows support advised I reinstall Windows 10 Pro and said that Windows 11 is really only meant for new PC's that come with it preinstalled. MSI website doesn't list my 2020 GT76 Titan dt-039 notebook on their Windows 11 upgrade eligibility list so I guess that's why the Windows 11 Pro upgrade failed. I suggest being careful with trying the Windows 11 upgrade despite it stating my notebook was capable of running Windows 11 it was wrong. Luckily I have the original Windows 10 Pro USB Flash drive because the Windows 11 Pro upgrade was so incomplete I had no way of reverting notebook back to Windows 10 without reinstalling from a USB Flash.

 

Reverting back to IE8

I manually installed the new IE9 Beta to try it out, but there are some issues with it and I'm looking to revert back to IE8. I tried going to my installed updates and I didn't see it there, it isn't under my installed programs list either.

Short of doing a system restore, what else can I do?

Windows 7 Pro 64-bit

 

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.
