YOUR SYSTEN WILL HAVE A CRITICAL ERROR IF YOU DONT DO THIS!!!!!!!!!!

How Do You Change The logon screen without screwing up your computer?
Its simple when this is unzipped open the folder C:\Windows\System32
find the file logonui.exe (DO NOT COPY OVER IT YET!!!!!!!!) now create
a backup of it by copying it to another location and keep that! then
restart your computer when its starting up press F8 and then when the
start-up screen comes up choose Safe Mode now log on to your desktop 
copy the logonui.exe (in this folder) into C:\Windows\System32 overwrite
the old one then restart your computer and enjoy the new logon screen!
thanks for downloading my logon screen
