Upgrade Windows 10 Evaluation to Full version easily

If 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.

Windows 10 banner logo devs 01 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:

  1. Open Registry Editor.
  2. 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.

  3. 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.

    What does it means by “Now you can upgrade it using the regular Enterprise ISO image”? and how to do that?

  5. jori

    Where did you get the “regular Enterprise iso image”? Or do you mean purchasing the Win 10 upgrade license through volume licensing and using that with the operation above?

    1. Sergey Tkachenko Post author

      It is not my business where the user got the Enterprise ISO image. The article assumes that you have it, regardless the method you used to get it.

      1. jori

        Yes but it is an unhelpful article if the full Enterprise iso cannot be downloaded or otherwise purchased

        1. EP

          sorry jori. you have to find & downloaded the full version of windows 10 enterprise yourself; neither Sergey nor I will do this for you. i mean you can easily figure this out by starting from Google.

    I have the Enterprise ISO, but can’t seem to trigger the upgrade, only a full re-install which defeats the purpose. How do you trigger the ‘upgrade’?

  7. Ira

    What’s the point of this, you still need a key for Windows 10, and no key out there works/lets you proceed. So it’s ultimately a complete reinstall after all..

    +the article is only for Win10EnterpriseEvaluation

  9. mame

    I followed the steps accordinglly but all the time I get an error after 10% of Installation saying “error on Installation of Windows 10”
    Is there any log file to see what went wrong? Or someone please have an idea f what went wrong?

    1. EP

      try creating a Win10 enterprise install media to a USB flash drive. then run the Win10 enterprise install thru the usb drive.
      I sometimes get installation errors because of bad installation media thru DVD media.

        OMG- Thats some Solid Advice EP. You really are ‘the man’

    This doesn’t appear to work with the latest version of the evaluation (Build 1563.rs2_release. 170317-1834)

    If I go through the setup with the Windows 10 Enterprise ISO then I only get offered a new install

    1. DataMan

      Yes Jon, thats right, this article needs ,,, hhhmmmm editing! :)

    2. Konstantin Dolgachev

      For Build 17763 you need change this values in registry:
      CompositionEditionID: EnterpriseS
      EdidtionID: EnterpriseS
      ProductNasme: Windows 10 Enterprise LTSC 2019

        @Konstantin Dolgachev :
        Thank you Mr. Dolgachev for posting this. The original guide didn’t allow me to upgrade and keep files. Using your params allowed me to upgrade and keep my files from my expired Win10 Enterprise Eval Build 17763.rs5_release.180914-1434.

    Hello Sergey,
    I installed windows enterprise eval.
    I changed the EditionID value data from EnterpriseEval to Enterprise.
    I changed ProductName value from Windows 10 Enterprise Evaluation to Windows 10 Enterprise.
    I used KMSpico 10.2.1Final and successfully completed installation
    Now Windows got activated!!! but windows 10 Enterprise Evaluation license message gets displayed on bottom right.what do you think happened? I’ll see tomorrow if “windows License valid for 86days” changes or not regardless of that, windows “evaluation” system got activated.can I get rid of evaluation message too from desktop?
    any comments?

    thanks & cheers,
    system admin

      Hello all,

      “windows License valid for 84days” remains today[used universal watermark remover].The evaluation days are ticking & “windows license valid message for x days” is getting updated.has anyone got a “valid days counter” patch?
      what happens to system if I go past 90 days?I guess it’s clock work

    Hi, Constructive criticism to follow Gents; your article is full of holes. Firstly there are three locations within the CurrentVersion that refer to Evaluation. Secondly and more importantly; the procedure Fails. Suffice to say I don’t believe you actually completed this process ‘Completely, from start to finish’ I believe you probably searched the registry, found a couple of familiar evaluation references, changed them, then kicked off the Enterprise install as an Upgrade. WOW – could have saved you a little time and suggest you use the DISM tools and follow the Microsoft Articles regarding there use. only limitation is that you can not change edition to an online install – you need to make a windows PE boot disk, boot off it, create an image of the Enterprise Evaluation installation, mount the image, run a couple of commands to modify the edition and insert the product key and Bam! your all good to go and rollout the image. Just Sayin…

      Well actually it does work!
      I just tried it with the dev vm Microsoft provides us, the latest version (1805) is based on win10 1803 so the latest one (as of now).
      You do have to change an additionnal entry in the registry, which was not present in earlier versions of win10.
      The entries to be modified are :
      – CompositionEditionID
      – EditionID
      – ProductName
      I removed Eval or Evaluation from these right before trying to “upgrade” to the full Enterprise edition using the en-us x64 iso and i can indeed upgrade while preserving files and applications.
      If it does not allow to keep apps and files, check the message at the bottom of the screen, if it says wrong edition id, then check again in the registry, i had to do it twice for it to stick long enough for the upgrade process to kick in…

    Thanks, Sergey! 3 years later and this still works perfectly. I just did it with the latest W10 1803 Enterprise EVAL with no issues and it really saved me from the needless pain of having to reinstall everything.

      Great. You’are welcome.
