Are you bored of seeing the same blue welcome screen??
then here is a way to change the login screen
first down load a login screen of your choice from the following url
htp://themes.belchfire.net/index.php?dlcategory=12
then extract the .exe file n save it to a directory say login_screen

*now open the registry editor
start>run>regedit>hkey_local_machine>software>microsoft>windowsnt>current version>winlogon

now on the right hand side locate uihost
right click that and select modify
and paste the address of the location where u stored your " .exe file"
for example: If u stored the > exe file on the desktop in the directory login_screen n the name of the exe file is 123
then your address would be
C:\Documents and Settings\Administrator\Desktop\login_screen\123.exe
and your done
