Windows 10 is coming out tomorrow. You want to install the latest Windows version to have the new OS features but you found out that one of your computer is running Windows 8 Enterprise edition which is not covered by the free Windows 10 upgrade.

    Thank you for such a clear tutorial. Could you tell me (or give an educated guess) as to whether I am likely to be successful if I follow the exactly “analogous” procedure in a situation which is exactly like the one here with the following THREE variations:
    1. I need to downgrade from Windows 10 Enterprise to Windows 10 Pro.
    2. Actually, what I **really** need is to downgrade from Windows 10 Enterprise Evaluation to Windows 10 Pro. (I have a valid Windows 10 Pro key).
    Finally, to make things interesting:
    3. I am some 3500 miles from the machine I need to downgrade, so I would like to do this using Teamviewer or remote desktop.

    Do I have even a snowball’s chance in Hell that the procedure you suggest will work? Using either teamviewer or remote desktop, I can mount a Win 10 DVD i have on the remote machine. So all the steps ‘make sense’ and can be done. Thank you for any informed opinion you might be able to share.

    (IN case you’re wondering why i would need to do something so stupid: On a recent visit with my mother, I learned that the dreaded Anniversary Update had hosed her perfectly fine installation of Win 10 Pro. Unfortunately, it even hosed the recovery environment. I tried various fixes I found online, whcih were based on the WIn 10 Enterprise Evaluation .iso that one can download for free. But nothing worked; in the end, I just installed that Enterprise Evaluation DVD, restored her apps and data, and took a plane home. Of course, now it is demanding to be activated,
    So I need to downgrade ‘back’ to Win10 Pro. And I need to do this without losing the installed Apps, because my mother can’t really install Teamviewer.
    Last question: Rather than mount the installation DVD remotely, could i just mount the .iso on the remote machine? I’m hoping that in your above procedure, the machine ejects the installation media before it reboots (because whether the machine mounts an .iso image or mounts the DVD on my desktop, the DVD won’t be mounted after the reboot.

    First of all I want to say awesome blog! I had a quick question in which I’d like to ask if you don’t
    mind. I was interested to know how you center yourself and clear your mind before writing.
    I’ve had trouble clearing my thoughts in getting my thoughts out
    there. I truly do enjoy writing however it just seems like the first 10 to 15 minutes
    are wasted just trying to figure out how to begin. Any ideas or tips?
    Many thanks!

    Right now it appears like Drupal is the best blogging platform available right now.
    (from what I’ve read) Is that what you’re using on your blog?

    Hi,
    I changed the information in Registry, after that i did reboot the windows.
    when Windows started I downloaded the Windows 10 Web Installation file and it’s started and it’s downloading now.
    it’s possible to install the windows 10 Directly after changing the Registry information without installing Windows 8 Pro ? or it will make a problem??

    Thanks

      There’s no such thing as a volume license for Win7/8/10 Pro. Volume Licenses are just for Enterprise and Education customers. There are OEM licenses for Pro – that’s what Dell/HP/etc buy to make machines with. But regular customers can’t get those of course.

        That’s incorrect. Windows 7/8.1 Pro editions can be licensed with MAK and KMS methods using corporate Volume Licenses.

    Is there a way to downgrade to Pro from Enterprise without the installation media? If not, how can I get the installation media for free?

    Is there any difference this time between Windows 10 Enterprise and Win 10 Pro other than license agreement? Do Microsoft have an official comparison chart?
