Windows Upgrade Help and more

+1 I had the same problem. For me, it was a piece of old security software that I had to completely uninstall before the upgrade would finally go through. Good luck!

You could also try a clean install from a USB drive, since the installer sometimes bypasses those checks. Another option is to double-check your RAM is actually running in dual-channel mode, as that can affect detection. Hope that helps.

Can confirm. Yeah, that's the way to go. A quick tip: make sure you back up any important files before you run the clean install.

I had the same problem trying to make sense of it all. For me, finally understanding the "Paged" and "Non-paged" pool was the key—it really clarified what was essential system data versus what Windows could move to disk if needed.
