Question Windows 10 Uninstall

Can you please clarify what it is you are trying to ask?

You don't really "uninstall" your OS. With Windows you can use the USB installer to remove the previous install partitions and leave the drive open and unallocated.
 
Ok, thanks for helping. I am trying to make my PC like I just built it and put it together. My current situation is previous programs (Avast and Windows Defender) along with the MB caused a lot of problems to Fusion 360, Syntheyes, Davinci Resolve. Black Magic Design said do a fresh reinstall. I have done that but I am still seeing issues on rendering. When I tried to reinstall Win 10 via their automatic help, I get a different set of questions then when I built another PC last month and used an iso from the website. So far no issues with the newest build. I am not a boasting just explaining, this will be my 13th or so PC build and have not encountered the little differences that I see. I don't want help recovering win 10 and having the program "fix" and give me a fresh install. I haven't had luck that way. I feel like that there is something wrong with the current os that can't be fixed, so, wipe and install iso from another computer. I have two NVME but cannot get to them to switch around or remove.

If you want a full clean install of Win 10...

Physically disconnect ALL drives except that which you want Windows installed on.

Then, this:
