Windows 10 product key upgrade eligibility CHECK online

We have a lot of laptops that we purchased in 2016 and then downgraded to Windows 7 Pro.  We do know the product keys.  However, BEFORE we install Windows 10 on each of these 9 identical laptops we must know if these product keys will also activate Windows 10.  I have so far, been unable to find anywhere online, especially on Microsoft's various Windows and activation websites, where to just do a simple CHECK to see if these are also valid Window 10 product keys.

Does ANYONE know how I can check these product keys that we used to downgrade to Windows 7, even though we should have been entitled to the upgrade to Windows 10 at the time with these same keys ???  I believe we used our MS Volume Licenses we had available for distribution at the time.

Any help or realistic guidance is appreciated.  Thanks !

Hi Art. I'm Greg, an installation specialist, 10 year Windows MVP, and Volunteer Moderator here to help you.

Normally with WIndows 10 Pro PCs that have downgrade rights, that is administered by the manufacturer's Support. But it doesn't change a factory preinstalled Windows 10 Product key's viability, so check first if you have that by running ProducKey from http://www.nirsoft.net/utils/produkey-x64.zip and look for the OEM-BIOS key. That's your Windows 10 activation insurance.

But you said you might have used your company Volume License keys so those would be under authority of MS Support which you can contact by one of these phone numbers:
https://support.microsoft.com/en-us/help/405170...
You can also go here: https://partner.support.services.microsoft.com/... choose the link for Browser help, interact briefly with the robot about your exact problem, keep replying "Agent "until it connects with an agent.

What we always know about Downgrade rights is that they may temporarily replace the Windows 10 license (or not) but you still have Windows 10 rights at any time to use for the life of the PC with embedded Factory OEM Product Key, or per the terms of your retail or Volume key.

You can either run an in-place upgrade to WIndows 10 by installing the Media Creation Tool from this link http://windows.microsoft.com/en-us/windows-10/m... choosing Download Tool Now, install the tool, open it and choose Upgrade this PC Now. This will save your files and apps while bringing you up to the latest version by the most stable method. It will also bring all of your Updates current and solve most problems since it reinstalls Windows.

Or you can do the gold standard Clean Install in this link which compiles the best possible Install of Windows which will stay that way as long as you stick with the tools and methods given, has zero reported problems, and is better than any amount of money could buy: http://answers.microsoft.com/en-us/windows/wiki...

I hope this helps. Feel free to ask back any questions and keep me posted. I will keep working with you until it's resolved.

Greg:

Thanks so much for your quick response and helpful links !  I'll give those a try.  I think that ultimately, however, we may have to just experiment with one of the identical laptops and do a fresh clean install of Windows 10 Pro (x64) which corresponds to the Windows 7 version now being used on those laptops.  Then, see if it activates successfully.  If it doesn't, then I will pull the current product key embedded in the machine that has been activated for Windows 7 and see if that does the trick for Windows 10.

I tried many times, unsuccessfully, yesterday to contact the manufacturer of the laptops - HP - and purchased through CDW, but no one at either place seemed to have a clue as to what we were "entitled to" when we purchased these 9 identical HP EliteBook 840 laptops in early 2016.  So, that is why I've been on this site almost as a last resort before just jumping into it and testing out my activation theory on at least one of the laptops where the user can do without it for a day while I experiment.

Ah, the life of I.T. staff in a live production environment!
