If some have boxes marked and the duplicates do not, mark the duplicates and
after rebooting, they should disappear.  Not all duplicates that are marked
should be removed as they are required.  Examples are the power profile and
antivirus settings.

Here are a couple of related articles:

There are seven run keys in the registry that are used to start programs:

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 there is an item disabled in the Startup tab, MSconfig.exe, that was in
one of these keys, it will be in an identically named key except that there
will be a minus at the end, i.e., Run-  I suppose any key could be
duplicated; however, I have only found keys #1, #2 and #5 duplicated in my
registry with a minus.  If you want to get rid of a non-marked entry in
MSconfig, delete the key with the minus sign behind it.

When you disable an entry that is in the startup folder on the start menu, a
folder is created on the start menu called Disabled Startup Items.  As
appropriate, delete the item from either the registry key or the Disabled
folder.  If the item is the only thing in the registry key or Disabled
folder, you can delete the key or the folder also.

Items can start from the run= and load= lines in the win.ini file.  If
disabled, they are placed in a norun= or noload= line.  Go into the win.ini
file and change the appropriate line back to the way it was, i.e., change
norun=<application name> to run= and save the file.

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 one of 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

There is a freeware program that makes this process a lot easier to
manage: Startup Manager, http://home.ptd.net/~don5408/toolbox/startupcpl/

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:

There are valid reasons why some items may be duplicated in the
Startup group.  LoadPowerProfile is one such entry, and it should be
left.  Some antivirus programs also create entries which appear to be
duplicates.

It is important to be fully aware as to the purpose of an item, how
and why it was put into the Startup, before making any changes.
Otherwise you could inadvertently remove something that is important
or at least useful.

Good luck
