Are/were you having this kind of problem with Desktop Display Properties? FYI: The pictures do not have to duplicate. It is the duplicate folder that is the problem. In the sandboxed My Pictures folder, there was only ONE picture while in my original My Pictures folder there were hundreds of pictures. By moving the sandboxed picture to my original folder and deleting the sandboxed folder, the problem was solved (for me). I checked right before/after doing this, and it made a big difference in Desktop Display Properties. In your case, you have TWO folders named My Pictures so if you are still having this problem, then Windows might be automatically listing all your pictures from My Pictures in Desktop Display Properties due to there being two My Pictures folders. You need to reduce it to only one My Pictures folder. To test this and be absolutely sure of what I'm saying, you'd ideally want to imitate exactly what I did by moving your personal pictures elsewhere (to different named folder or original My Pictures folder) -and- deleting the alternate My Pictures folder (you can retrieve it from the recycle bin anytime) which is located on your D drive. But another approach (although I'm not sure it could work this way), you can rename your My Pictures folder (on D drive) to MyPhotos. You can change it back later if you want. Also use the search function to find any other folders named My Pictures to make sure you, as profile user, are using only one My Pictures folder. Keep doing the renaming of My Pictures folders (except the original) until you are all the way down to only the original. Keep track of those folders so you can come back and rename them later if you want. See if this fixes the problem, if the Desktop Display Properties issue is/was even a problem for you. I am addressing the fact that you have at least two My Pictures folders - irregardless of files not matching in both folders. If this does not work for you, it could be something else. I am just stating what has worked for me as the issue was exactly the same others were having. My solution fixed the problem (for me), and it might help others.
