有些程序默認開機就運行，會影響開機速度。可以把他們關上：

(1) Start > Run > msconfig > “Startup” tab > Uncheck unnecessary programs (keep virus-scanner and firewall and may need some experimenting with others).


(2) Start > Programs > Startup; if you remove the shortcuts from this directory, the applications will not load on startup.
