Thanks for the response, however I think perhaps you either didn't understand my post or didn't fully read it. I am not having an issue with changing the logon screen background. I am having trouble getting the OEM User Icon to go away on the Logon screen (the icon that defaults to the Sun Flower or whatever), even though I have updated my user account to have a different user icon.
Give my original post another read and if there is anything I can clarify please let me know. I would upload a screen shot but this forum is pretty limited. Perhaps I will post it somewhere else and link it.
