I installed a refurbished computer today. I'm assuming it was a clean install of W10 Pro from some image. It didn't activate automatically. I had to enter the provided license key to activate Windows. That went fine. I found there were two USB ports in the back that would not recognize the USB-connected printer or USB mouse. I didn't even get the ba-loop sounds when plugging them in or removing them. They did however recognize a USB flash drive. Other ports recognized the printer, mouse and USB flash drive. I didn't check the keyboard. Any one else seen this or know why a USB port would recognize a flash drive but not a mouse or printer.
