Reg Method for Removing Startup Items

I prefer to use MSCONFIG selective startup to troubleshoot. To remove entries for good, open the registry:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

Delete entries of unwanted startup daemons and tray procedures.

To remove disabled items from the startup list in msconfig delete unwanted subkeys of
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SharedTools\MSConfig\startupfolder
and
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\MSConfig\startupreg
