Many applications that are installed on Windows 7, XP, and Windows 8 are set to autostart. This allows applications to load faster because they are already in memory, but having too many applications autostart will lengthen the time it takes your computer to boot.
To remove programs from auto starting on the taskbar.
Start => Run => type “msconfig” => This takes you to the System Configuration Utility
select the “startup” tab => uncheck everything you don’t want to run when the computers starts.
