Windows 10: Is it possible to activate windows 10 with windows 7 OEM key?

Im building a new pc and I have an old laptop with windows 7 oem licence. As far as I know it’s still possible to upgrade from 7 to 10 for free but is it possible to use the laptops activation key to activate windows on the new pc? If not, is there some other way to utilize the key?

Windows 7 OEM key

Hope this is not against the rules. If you do a clean install of Windows 10, it may, (has for me) accept a Win 7 OEM key and activate.

There is no difference between the OEM disc and the Retail disc with Windows 7. A retail disc will accept a OEM or Retail key, and vise versa.

If the OEM Key wasn't going to work with the disc you have, it would have stopped you during the install when it first asked you for the key, not during activation.

What is likely the problem is that, since the OEM version has already been activated once, it is failing activation again. Activate it over the phone using the option given to you on the failed activation screen, and you shouldn't have a problem activating it.

 

Guide: use Pre-activated Windows 7 OEM License on fresh installation

Is it possible to transfer Windows 7 Home Premium OEM activation backup to fresh installed Windows 7 Ultimate SP1 media refresh on the same system? Because I am planning to reformat my laptop and change its OS to Windows 7 Ultimate SP1.
