Is it easily possible to customise the generic lock screen rather than each individual users? There is a program from Winaero which leads you to other downloads and may be dodgy. I have decent screens for all users but then when you log off it isn,t the Denver Needle? that appears but the swirl of colour thing which I would like to change. Google searches do not seem to allow for this but I don,t know why as most items seem customiseable.
