This tweak allows you to change the background bitmap image in the MSN Messenger service.

Locate the installation directory for MSN Messenger on your system (e.g. "C:\Program Files\Messenger"). This location can also be found in the registry in the "InstallationDirectory" value at [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MessengerService].

Rename the "lvback.gif" file in the installation directory to "lvback.old". Then copy and rename the new background GIF file to the same directory as "lvback.gif".

Restart MSN Messenger for the change to take effect.
