Heres just an example of logins i have made using
Logon Studio can be downloaded (free) from here

I mentioned in the Vista thread to use ResEdit or Resource Hacker yet dont bother using those unless your familar with Dephi programming

Logon Studio is way easier and your be making sub logins in 10min. Just click & add - "Its easyware".
You do not need StyleXP to enable your logins, Logon Studio will apply it for you. Its also backs up your original login.
Ive made two for my winxp login so far, one uboat and the other kilo logins as you can see its not fully finish theirs heaps more you can do like add in banners for the top and bottom change the look of username windows etc., and i have to work out how to get rid of that line in the centre!
You can also add your work to wincustomize for others to DL. So get creating Kapitans!
