Dark Win10 wallpaper
I think there was some discussion here on how to get the old Windows 10 dark
blue wallpaper, and someone suggested manipulating the new, lighter image
through the properties.
There is a much easier way. If you have another PC that still has the dark
wallpaper, log into it, open the Windows Settings, and go to
Personalization--> Themes. Now find the dark screen on the Change Theme
selection, right-click on it and pick "Save theme for sharing" - when the
dialog box opens, save it to a thumb drive.
Now take that thumb drive to the new Win 10 PC, and find that file in the
thumb drive with Windows Explorer. When you see it, double-click on it. It
will install in your new PC automatically.
It would be a good idea to save the shared theme file. You might want to use
it again.
