I am having same problem. installed 8.5 to make sure i had current however when I try to use it, instead of displaying background it goes to a black background, No picture displayed
That's a totally different issue.
This thread is about the Windows 10 installer blocking installation of the November update because Deskscapes is installed.
Your issue is one after installation.
My recommendation for you is uninstall, reboot and reinstall. If problems continue make a new thread with all the details including graphics card information and what dream you are trying to use.
