Yeah, it is a good question and I've started telling people to only leave one unless there are multiple users or logins.
Another one of those behavior is by design
Microsoft has a little info on it:
LoadPowerProfile Starts Twice When You Start Your Computer
------------------------------------------------------------
The information in this article applies to:
Microsoft Windows 98
Microsoft Windows Millennium Edition
------------------------------------------------------------
SYMPTOMS
When you view the programs that are loaded when you start your computer, you may notice that LoadPowerProfile is listed twice.
CAUSE
This behavior can occur because LoadPowerProfile is started twice to provide a power management profile before and after you log on to Windows. LoadPowerProfile starts as a machine service so that the default power management settings are available when Windows 98 starts. It is loaded again after you log on to Windows to process preferences for individual users of the computer.
STATUS
This behavior is by design.
The run= hpfsched is unneccessary. it relates to a HP printer.
