3. Disabling Unused PORTS

I have just accidentally found out another way to give you an extra boost in windowsXP's boot performance. This is done by disabling your unused devices in
Device Manager. For example, if you don't have input devices that are connected to one of your USBs or COM ports, disabling them will give you an extra perfromance boost in booting.
Go to Control Panel > System > Hardware tab > Device manager
Disable devices that you don't use for your PC and then restart.
See the difference foryourself.
