I've just spent the weekend building a new computer with an i3-7100 and Windows 7. I am getting the Unsupported hardware message. I didn't know this hardware was unsupported until after I was done and booted. I know there is the EE post https://www.experts-exchange.com/questions/29066579/unsupported-hardware-for-windows-update.html
saying essentially, "too bad for you - upgrade to Windows 10", but that is not an option in this case. This is a hardware upgrade for an office computer and Windows 10 is currently not authorized.
Most sites I've got to say this message can be removed by uninstalling KB4012218, KB4012219 and/or KB4015549. None of these are installed on this computer.
Is there any way to disable this message?
