Am I missing something here? Two unanswered questions:
1. What is the evidence that Windows 8.1 is "still running in the background"? The Windows logo screen (with a "window" image, there is a whole set of them in C:\Windows\Web\4K\Wallpaper\Windows, and one image in C:\Windows\Web\Wallpaper\Windows) appears for a moment at Windows 10 startup, as it did in 8.1, but that doesn't AFAIK mean 8.1 is still running somewhere. I have two laptops recently upgraded from 8.1 to Windows 10, and find no evidence that Windows 8.1 is running in the background there.
2. Why delete the Windows.old folder? It is there, I suppose, to allow you to roll back the upgrade (for a time) if you want to - but there are also things in there you might find useful, at least so I have found. I can see a point in that if you are running out of hard drive space, but otherwise?
Maybe I am just missing the point here?
EDIT Ack, wrong image set . . . sorry
