Q. I just upgraded to windows 10 from windows 8.1. I had created my own theme in windows 8.1 with my own pictures, I would occasionally add or remove pictures from my custom theme. In windows 10, my theme is still there but I can’t figure out how to add or remove certain photos. I also don’t have the original pictures on my computer because I dragged and dropped them into the theme on windows 8.1Where are the themes’ pictures files stored? Or how can I edit my theme as I did in Windows 8.1?
You added in a “/” there. You need to enter exactly
as the path you’re trying to go to in the File Explorer address bar if you want to do it that way. Or you can run exactly:
control /name Microsoft.Personalization /page pageWallpaper
from a Win+R (Run) prompt to select/unselect sub-photos in the theme.
