Hi
Roro1972. When I read this I was under the impression we could search for wallpaper, do a right click on it and copy an URL link to the individual selection we wanted, and then recall it in the future if needed. That didn't work, and clicking on it changed my wallpaper to something I sure didn't want. Not wanting to go through it again, I decided to go to Restore Your Computer to an Earlier Time. My old screen was back, but none of the Favorite Shortcut Icons to internet connects now worked.
I got my Computer man on the phone that gets me out of truble at $1 per minute using a Team Viewer program, and he quickly found that my Explorer on Windows was missing, and that the problem was due to some virus that has got into the wallpaper portion of my computer options. He flew through numerous programs to my amazement selecting this & that and got me back on line in about five minutes. You mentioned that a certain wallpaper you once had was no longer available, and I suppose that probably to demand. On your program, do you have option of selecting a Restore Your Computer to an earlier, which I believe would also restore you old walpaper; it did for me.
