load

HKCU\Software\Microsoft\Windows NT\CurrentVersion\Windows
Data type Range Default value
REG_SZ [Path]File name(s) (This entry has no default value.)
Description

Specifies the programs that run when Windows 2000 starts. The programs are minimized (appears as a taskbar icon) while they are running.

This entry stores a list of file names of programs or files associated with an application. Each file name must be separated from the others by a space. If the file is not located in the Systemroot directory, you must specify the path to the file.
Change method

To load a program at startup, add the application to Systemroot\Documents and Settings\All Users\Start Menu\Programs\Startup. Right-click the icon, click Properties, click the Shortcut tab, and select Minimized from the Run drop-down menu. This will not actually change the value of the load entry, but it will emulate the behavior.

Edit:Maybe these?
