Where are the images from Windows Spotlight coming from? Where are they being saved on my system? Is there any way for me to point this at my own source of images?
Solution:
The pictures are located at:
C:Users{your_name}AppDataLocalPackagesMicrosoft.Windows.ContentDeliveryManager_cw5n1h2txyewyLocalStateAssets
And they will look like this:
Renaming these to .JPG will reveal it as a picture but I am not sure there is a way to generate the names. So the only idea I have is to note the existing names and rename your own pictures to match them…
