Hithere,
Not a problem, I can help you there
You are correct, Quicktime does not need to constantly be running in the background. In fact, it is a totally unreasonable resource hog – it has been measured to use as much as 1.5Mb of memory at times.
Quicktime--Start QuickTime through "Start \ Programs", choose the "Edit \ Preferences" menu option, select "QuickTime Preferences" from the right-hand side menu, uncheck the box next to QuickTime System Tray icon. In version 6, however, this is done differently : double-click on the QuickTime icon in the Control Panel to bring up the QuickTime Settings panel, choose Browser Plug-in in the drop-down at the top, and then uncheck QuickTime System Tray icon.
There are a few others that can be disabled from startup, yet still accessible from desktop when needed.
See this
link for a full lists of processes, what they are and if they're needed.
To disable an item from StartUp:
Click Start>Run and type in
msconfig or msconfig.exe. It will bring up all the programs/processes that load when Windows loads. Look for the processes and 'Uncheck' them. If you find that you do want process running at start up, just go back in there and 'Check' it again.
