f you are testing an evaluation version of Windows 10 and decided to
upgrade to the full version, you will face a stumbling block. The
evaluation version offered is of the Enterprise edition but Microsoft
does not support any way to convert the evaluation version to a fully
licensed version of enterprise edition! You cannot change the edition
with DISM commands or using any other method. Even if you download the
ISO image of the enterprise edition of Windows 10 and try to upgrade the
existing "evaluation" OS, it will not allow you to proceed.
Here is a workaround which lets you upgrade Windows 10 Evaluation to the Full version easily.
Using a simple Registry tweak, we can unblock the upgrade and use the setup program of the full version on the installed Windows 10 evaluation edition. This will preserve all installed apps and settings. Follow these simple steps:
- Open Registry Editor.
- Go to the following Registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
Tip: See how to jump to the desired Registry key with one click.
- Change the EditionID value data from EnterpriseEval to Enterprise. Next, change the value data of the ProductName value from Windows 10 Enterprise Evaluation to Windows 10 Enterprise.
Now you can upgrade it using the regular Enterprise ISO image! After the upgrade, it is possible to activate the upgraded OS using your regular KMS server or MAK key.
That's it! Using the same trick, you can also change the edition from Enterprise to Windows 10 Pro if you need. It works like a charm.
