1.) This could be a registry error or possibly a driver issue. Some refurbishing companies are notorious for swapping a motherboard out with a “compatible” board. Yes the CPU and everything seems to be fine but the video card may be a different version (not talking model but version of BIOS on the video card).
2.) If you contact your Microsoft vendor and give them all your single licenses they will combine them up and give you a volume license for as many single licenses that you have. This will negate all the single licenses but now you have a useful volume license. Then, you can just load the volume license on the image and not worry.
