get path to current desktop wallpaper

Question

As mentioned in the title, I want to get the path to the current desktop wallpaper (in C++). I tried to use SystemParametersInfo with SPI_GETDESKWALLPAPER. But this only returns this:

%AppData%\Microsoft\Windows\Themes\TranscodedWallpaper

What I really need would be something like this:

C:\User\...\image.png

Is there any way to achieve this?

Answer 2

• TranscodedImageCache_000
• TranscodedImageCache_001
• TranscodedImageCache_002
• TranscodedImageCache_003
• TranscodedImageCache_004
