Windows 7 Folder On Desktop

I have read elsewhere that installing Windows 10 top of Windows 7 results in a windows.old folder, which does seem to exist on my computer.

Instead, I have, on the desktop, a folder, Windows 7, which seems to contain many of the files, etc., perhaps all such data, that were in Windows 7, such as all of the folders under Documents. I just looked at Documents in the Windows 7 folder, which even shows a file that I put into Documents in Windows 10 on 3August2015. In fact, looking at the folder,it looks just like what I see when I use the Windows 10 File Explorer from the icon on the task bar.
