Under Control Panel/System-General Page you can add both a Logo and a "Support Information" Button with just two...
files added to your WINNTSYSTEM32 folder. An example for OEMINFO.INI is shown. This file creates the Support Information Button. The second file is called OEMLOGO.BMP, and this can be a graphic logo complete with text, sized to fit in the box outlined under the Monitor Picture. Just create, name and place these files in the user's WINNTSYSTEM32 Directory with your logon script, and it's done. Works with both Windows NT and 2000.
