Windows 7 Problem changing or restoring logon screen - Help plz !


New Member
I tried resizing an jpg with Paint to use it as logon screen and before to save it a message showed saying that i will lose the transparency of the file but I save it and applied anyway.
My mistake cause since then, whatever I tried, I can't restore or replace that ugly thing that I created. I used "Windows 7 Logon Background Changer 1.5.2" , I did it manually by editing the registry but always the same thing, background changes but the white small window from the center it's always there and I can't get rid of it !
Is there any way to restore or change that ?
Thanks ... I would like to to attach a screenshot but I don't know how !
Help please !
