My rule of thumb is if the program doesn't get used during nearly every
computing session, then there is no reason for it being started at boot.

To cut back on the number of programs starting at boot, check the programs
themselves for an option not to load.  You might have to double click an
icon in the tray (others might require a right click) and then look for
preferences or options.   If you cannot find an option, look for the program
in the following start up points and remove the reference to it:

Start up folder on the start menu, the load= and run= lines in the win.ini
and these registry run keys (use regedit.exe):

1. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run

2. HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

3. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce

4. HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

5. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\ RunServices

6. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
RunServicesOnce

7. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
RunOnce\Setup

If poking around in the registry is not for you, there is a freeware program
that makes this process a lot easier to manage: Startup Manager,

You can use msconfig.exe, startup tab, to disable programs; however, by
doing so, you may lessen its value as a troubleshooting tool.  There might
be some double entries in msconfig--leave those for your AntiVirus program
and load power profile alone as they are required.  If you disable an entry
in msconfig or remove it from the start up point and the program loads again
after a reboot, that is an indication that you missed an option on the
program itself.  If you don't know what an entry is, check here:
