I may not see what you see. On that page I see four large icons: Windows 11; Windows 10; Windows 8.1; and Windows 8. I would follow the process that I wrote, in the link that I gave you. Many forum members have followed it and had success with it. 
About a week ago, I had to do a factory reinstall using SupportAssist.  Dell techs worked 1 1/2 hours to try to fix.  It didn't go well, but I eventually got things fixed myself.  I was not at all impressed with SupportAssist, and if I ever have to do an install of the OS, I will use Microsoft's Media Creation Tool and do a clean install: [URL] The install would  be on this same machine, on the SSD. I have two questions: 1) What's the difference between the 2nd and 3rd methods? 2) I don't understand how Microsoft knows the Product Key of my OEM install.  How is this conveyed?  Can I find it out? Thanks.
