Disabling Unused PORTS in Windows

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 for
yourself.
Bonus Tip: Perform a Boot Defragment

There’s a simple way to speed up XP startup: make your system do a boot defragment,
which will put all the boot files next to one another on your hard disk. When boot files
are in close proximity to one another, your system will start faster.
On most systems, boot defragment should be enabled by default, but it might not be
on yours, or it might have been changed inadvertently. To make sure that boot
defragment is enabled on your system, run the Registry Editor and go to:
HKEY_LOCAL_MACHINESOFTWAREMicrosoftDfrgBootOptimizeFunction
Edit the Enable string value to Y if it is not already set to Y. Exit the Registry and
reboot. The next time you reboot, you’ll do a boot defragment.
