I recently replaced Google Desktop search with MSN Desktop Search on my computer.
I like the ability to create shortcuts to launch various files, programs and sites.

Your deskbar shortcuts are stored in the MsnDeskbarShortcuts.ini file. This file is located in the C:\Documents and Settings\username\application data\MSN Search Toolbar folder.

Here is how to reduce the space taken up by the MSN  Deskbar toolbar.
A  Summary:

Find this folder in your registry:
HKEY_CURRENT_USER\Software\Microsoft\MSN Apps\DB

Next,
add a DWORD value with the name of "Buttons" and change the value of
"Buttons" to "1". On your toolbar, uncheck the MSN Deskbar to clear it
from your toolbar then re-check it to add it again without the button.
