I have my new computer mostly built I just need to put in my old drives, graphics and psu. My question is can I use my ssd with windows on it (bought key off newegg 8 years ago, script in command prompt says retail). I would love a fresh install of the os without losing data like pictures,documents and game downloads. What is the best way to do this? Last time I built it was just a new fresh install on an empty drive.
