Win 10 activation is expiring - volume license


Finally got it activated but still confused as to what is really going on with activation.

here is what I did:

-got another Win7 Pro key from a friend (non volume license one)
-I tried to activate it, but it gave the same error message as before, "could not activate with this key"
-following suggestion above, I tried it a second time. This time it activated !!! (internet was connected both times)

don't know why just doing it 2 times makes it work. maybe someone else can explain that.

I checked it with ShowkeyPlus and to my surprise it now said it was activated and showed the installed key as the generic Win10Pro key that is listed in above post. But I did not enter that key. ????

 

FORGOT ACTIVATION PRODUCT KEY

Windows 10 Enterprise is a volume license client, which can be activated multiple ways depending on type of licensing.

If you got the license through your organization, you might be able to activate by logging on to your organizations domain or VPN into their network.

If you have an assigned product key, try using the volume activation center for your region to activate:

Try the appropriate phone number listed here: Microsoft Activation Centers Worldwide Telephone Numbers:

Is it possible to use a Windows 10 product key to activate a Windows 7 installation?

According to Microsoft, you can't use your Windows 10 keys. You will have to call Activation Support, provide proof that you have a license with downgrade rights, and they will provide a response to the activation challenge that will result in a one-time activation of an install.
