Windows 10: Activation/ product key not accepted

Hi:


I checked out Win 10 PRO using a place holder key but now I am not able to roll it back to my OEM Win 10 HOME version of windows.


I tried some steps like updating the registry to HOME from PRO and then mounting and running the ISO for WIN 10 but it doesn't work. It asks me for my product key and when I enter it I get message "This product key didn't work. Try a different key or buy a new one"


Any help in this regard is appreciated.


I was following this post to down grade from the PRO to HOME https://answers.microsoft.com/en-us...-to-home/345f5464-cb7a-44b3-8856-237cbec072c8

Activate windows 10 after re-installing (I have lost my product key)

I own a Lenovo T430 laptop. In 2017, I installed Windows 10 using my original Windows 7 product key. Unfortunately, I cannot find that product key anymore. I need to re-install windows 10. Will it be automatically activated after the installation, if I skip the step of asking the product key during the installation?

In my opinion, I believe that my laptop will have a digital entitlement stored on the Microsoft Activation Servers and this will not be a problem. Is that true?

If not, please suggest me a solution or a workaround.

 

Valid Win7 Product Key not accepted by Win 10 upgrade

Hi,

I did not realise I had been at all vague, my apologies.

Unfortunately my neighbour now has his laptop back as I got nowhere. I have suggested he wait until the windows 10 upgrade system makes it available through windows update (it is in the queue).

As stated, I have tried running from the media created by the media creation tool to a USB (this is what I used to successfully upgrade my laptop and surface Pro). I have also run the media creation tool and opted for it to upgrade directly rather than save the files.

The operating system is Win7 Home premium OEM version. The key is valid and I re-validated it to be sure with the MS online actvation system. The laptop is 64-bit.

On each occasion it goes through the initial install steps and then gets to the screen where it asks for the product key.

On this screen there is no skip option and as the product key is not accepted, the only option is to cancel the install.

For some reason the upgrade seems to be taking a different path on this machine and does not give the skip option.

Regards
Mike
