TZ startup items

Hi,

I'm trying to boost by boot up speed by disabling startup items under system configuration. Are there things which i should leave/disable? there are so many services and startup items that i don't wanna mess with it without knowing what it will do. thx

 

Here are some start item in TZ . (I'll add lot more because im not infront of my notebook right now ) .

Intel(R) Common User Interface - igfxpers.exe - Part of Intels Common User Interface for chipsets with integrated graphics controllers - which allows user to change different driver properties through Windows User Interface. Not known exactly what it does but apparently it isn't required

Intel® Common User Interface - igfxtray.exe- Part of Intels Common User Interface for chipsets with integrated graphics controllers - which allows user to change different driver properties through Windows User Interface. Quick access to the control panel via a System Tray icon. Available via Start -> Settings -> Control Panel

smartswitcher - used for wireless automated function

Windows Defender - MSASCui.exe - Related to Windows Defender Microsoft (anti-spyware) tool

ACROTRAY.EXE - Used to create PDF files with Acrobat Distiller. For Win9x/Me systems you can run this file manually beforehand. For WinXP systems this file must run at startup. Hence the "U" recommendation. *.* represents the version
