hello to all

i recently dwnlded some apps ( Autoruns / LoadOrder / PageDefrag )
from sysinternals.com ; and all apps are working just fine.
ive already a startup items control application for a long time
and now ive a machine with WindowsXpPro+SuseLinuxPro and i thought
the windows startup items were in the same folders + registry keys ;
this is not the problem , the problem is that the Autoruns app shows
me entries in the registry that i never thought they were starting
with my computer , here are the app display :

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\ShellServiceObjectDelayLoad\
+ PostBootReminder -> %SystemRoot%\system32\SHELL32.dll
+ CDBurn -> %SystemRoot%\system32\SHELL32.dll
+ WebCheck -> %SystemRoot%\System32\webcheck.dll
+ SysTray -> C:\WINDOWS\System32\stobject.dll

if any1 can help me i would like to have the minimum possible
since ive the minimum runing apps+services running , even
the printer service i only activate when i need

please feedbak me
