Turn Off redundant interfaces to achieve optimal performance for Windows

Because of its many advantages, Windows XP has become the preferred Operating System for notebook users. It is compatible with various external interfaces, drivers with USB, IEEE1394, PCMCIA, and other standard interfaces are a major advantage.
However, for many notebook users, especially for commercial purposes, many interfaces are rarely used. For example, the most commonly used interfaces are Ethernet interfaces, the infrared interfaces are rarely tested, but the PCMCIA and 1394 interfaces are useless.
What we call an interface is actually a device. To make these devices work in the operating system, you must first load the driver to occupy system resources, and then consume electricity. But if you don't need it, isn't it futile? For a PC, Several Interfaces consume a little power, but for a notebook, it can save.
To disable a device that will not be needed at half past one, it is most convenient to operate in the Device Manager, here, we can "Disable" the commonly used parallel port, serial port, floppy disk interface, and 1394, infrared interface. Simply put, we can block the sound card when we don't listen to the song-this is not too much, the laptop is configured with the AC '97 "soft" sound card that requires CPU service, the resource usage is not small.
To disable some of the devices mentioned above, you can make more thorough adjustments in the BIOS. However, you can use the Device Manager to conveniently disable the devices, both of them are more convenient when you need to re-enable Windows.
Disabling unnecessary system services is also a common method to squeeze the last point of system performance. Some services are directly related to interface devices, for example, the Infrared Monitor and Smart Card services used to display the Infrared connection status. The former is used to display the connection status of the infrared device, and the latter is used to manage the smart card, so some services actually do not have much practical effect. We set the launch nature to "Manual" to save system resources.
In addition, services such as Messenger, RPC, and Remote Registry that are not very useful but are most vulnerable to attacks are also well set to "Manual" mode early.
