Windows 10: Windows 8.1 Enterprise to Windows 10?

Hi,

I have Windows 8.1 Enterprise and would like to upgrade to Windows 10. I understand that it isn't possible directly, but I do have an unused Windows 7 key that I can use. Is it possible to perform the upgrade without having to do a fresh install?

Regards,

Matt.

Unable to reserve Windows 10, how to reserve it?

You are running Windows RT 8.1

This version of Windows is not eligible for the free update

Some editions are excluded: Windows 7 Enterprise, Windows 8/8.1 Enterprise, and Windows RT/RT 8.1.

 

Win 10 upgrade for corporate PC's

According to Microsoft, no.

Some editions are excluded: Windows 7 Enterprise, Windows 8/8.1 Enterprise, and Windows RT/RT 8.1. Active Software Assurance customers in volume licensing
have the benefit to upgrade to Windows 10 enterprise offerings outside of this offer.

 

The best would be to do clean install and enter your 7 key.

However (as you said you don't want to) what you can try is changing the edition before you upgrade:

Open up regedit (search for it in the start menu), go to "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion" and change "EditionID"to"Professional" and "ProductName"to"Windows 8.1 Pro"

Upgrade then activate with Windows 7 Pro key. If your 7 key is not 7 Pro then you'll need to use the equivalent names in the registry for the 7 key that you have. Windows 8.1 EditionIDs? - Super User

I don't now if would work but it should do. Make sure you use the correct Windows 10 ISO (Home or Pro) for your 7 key - Ultimate and Pro -> 10 Pro, everything else is 10 home.

 

The only upgrade from 8.1 Enterprise is Windows 10 Enterprise and that isn't free. You can use your Windows 7 license to upgrade to Windows 10 for free, but be aware you will lose the enterprise features.
