I am upgrading my computer by replacing the case, motherboard and processer as well as adding a SSD and more memory. I plan to use the existing power supply, HDD, video board etc. I also got a copy of Windows 10 as I understand that you need a new copy if you change the motherboard. Would it be easier to get Windows 10 working on the HDD, add the SSD and then move Windows to the SSD along with a couple of other programs, or install the SSD, Windows onto the SSD, followed by adding the HDD to the machine? If clean installing Windows on the SSD, how do you delete the operating system on the HDD as well as get the other programs on the HDD to work?
