Thank you for contacting the Intel community.
In this case, you could install Windows® 7 with this processor but you will need to use the Windows® graphics driver because there are no drivers available for the graphics on this and Windows® 7.
Also, I suggest you to contact your Mini PC manufacturer and ask them if the system supports Windows® 7 or if you will be able to install it because this also can be a limitation from your computer manufacturer that will allow the installation of Windows® 10 only.
You computer manufacture may alter the features and specifications and for that reason they will give you better information about it.
You can provide me with your system model and I can try to look at their website to find out more information.
