OK PEOPLE!!! Here is my EASY solution: I messed with everything on this laptop (Account Picture Folders, Default Account Pictures Folders, the registry, etc) and I learned that the LOGIN screen gets the single image to display the user picture from the file C:\ProgramData\Microsoft\User Account Pictures\user.png. I took a copy of the picture that I wanted there and opened it with Paint. Changed the .jpg to .png. Then resized it to 448 x 448 pixels. I replaced the default file of the same name with that picture. Logged of and back on - PICTURE WAS THERE!!!! F'in DONE
