Variant Win XP hardware configuration file uses

Windows XP has a hardware configuration file that saves the installation information of all hardware devices. At startup, it can control the corresponding device and configuration required for system startup. However, under normal circumstances, many friends will only operate the hardware in the "Device Manager", and most of them ignore the function of the hardware configuration file. In fact, if you use the hardware configuration file reasonably, it will further improve the operating efficiency of Windows XP.

First, clear the extra hardware information

after uninstalling hardware, the hardware configuration file does not automatically remove all the hardware information hardware configuration file. Therefore, after replacing the hardware multiple times, a lot of useless hardware registration information will be left in the system, and when the system starts up, it will repeatedly communicate with these non-existent devices, which will slow down the system. At this time, it is necessary to speed up the system startup by clearing the redundant hardware information in the hardware configuration file.

Right click on the "My Computer" icon and select the "Properties" command. Switch to the "Hardware" tab in the open window and click on the "Hardware Profile" button. In the dialog that opens, click the "Copy" button to back up a hardware configuration file (Figure 1).

Restart the system, there will be a prompt to select the hardware configuration file, select "3.None of the above" item, Windows XP will re-detect the hardware and generate a new hardware configuration file . After entering the system, delete the original two hardware configuration files.

Second, avoid re-activate the system after

in Windows XP frequent replacement of hardware devices, you will be required to re-activate the operation. The process of Windows XP activation is very cumbersome, but with hardware configuration files, you can avoid such problems.

Before each installation or change of hardware, back up the original hardware configuration file "Profile 1", just click the "Copy" button under the "Available hardware configuration file" check box. Copy the original hardware configuration file. In this way, if prompted to reactivate afterwards, re-import the backup hardware configuration file. //This article comes from computer software and hardware application network www.45it.com

Third, quickly switch between different working environments

Friends who use laptops often have to use hardware in different environments. Reconfigure. If you can use the hardware configuration file, you can make the laptop run faster and more efficiently when you switch to the working environment.

First, you can create two hardware profiles by copying. One is "Docked Profile" and the other is "Undocked Profile". After launching with "Docked Profile", open "Device Manager" to disable some hardware devices, such as network cards, etc., and in the configuration file management dialog box, click the Properties button, check "This is a portable computer" and " The computer is not plugged in (see Figure 2).

Figure 2
After deactivating a device in a hardware profile, the driver for the deactivated device will not be loaded when the computer is started with that profile. In the future, you can use the “Docked Profile” in a place with power to start all hardware devices to complete complex work. In the mobile environment, you can use the "Undocked Profile" to start only the necessary hardware devices to complete the work, achieving efficient power saving.

Fourth, effectively avoid hardware conflicts

due to compatibility issues, some of the computer will produce some difficult adjustments, a hardware conflict, by this time may wish to create multiple hardware profiles, respectively, to start a separate Conflicting hardware, avoiding the "one can't use" flaw. Take a computer as an example. After a few minutes of dial-up Internet access in a LAN, the network card works normally, the network speed is very slow, the mouse dies, and the CMOS and system resource configuration problems still exist. The test found that the motherboard and network card compatibility is not good, the resources are seriously conflicted.

First, in the hardware configuration file dialog box, rename the current hardware configuration file to "Internet", then copy it and name it "LAN". Restart the system, select the "Internet" configuration file, then delete the network card in the "Device Management", adjust the COM port of the Modem, so that it can dial the Internet normally. Restart the system again, start with the “LAN” configuration file, delete the COM port where the cat is located in “Device Management”, and adjust the network card resources to make the network card work. In this way, when the system is restarted and selected and started, it can be used in different environments by entering the LAN mode or dial-up hardware.
