I know Microsoft may not want this but as long as you don't want to make new users you can just use the "trial" version of windows. Just download the ISO from microsofts website then just make the USB bootable and just do all the steps but when it asks you the the activation key just press I don't have a key and just do the custom set up. This is the OS I use and it works perfectly fine. I have used it for over two months now
