Stop boot-up loading of several undesired TSR Programs

I am running Windows 98 First Edition on my HP Pavilion 6465 PC. When I do
“Ctrl+Alt+Del� immediately after boot-up a pop-up window titled “Close
Program� appears which tells me the programs that are running. On my
computer there are 23 programs loaded immediately after the boot-up has
completed. What loads these programs upon boot-up and how do I PERMANENTLY
stop the loading of several of these programs that I don’t need. Removing a
program by way of “StartSettingsTaskbar & Start MenuStart Menu
ProgramsRemove(Un-click program)� does not remove the program from the
“Close Program� pop-up window when the computer is rebooted, also many of the
programs don't appear in the Start Menu Programs folder.
