So I am building a new gaming pc and bought windows 10 from newegg. But how will downloading windows 10 work if this pc already has windows 10? Do I just download windows 10 iso and put it into a usb, and windows will ask me for a serial code when I plug the usb drive in??
OK, the first post indicated that the computer already had Windows 10 installed. The just download Windows 10 and put it on a USB stick and install and skip the step that asks for the product code, you can activate it later.
