talking about hardware profiles, there are many of my friends have ignored it in windows xp in the role, in fact, if used properly, it can greatly improve the efficiency of the system what
the hardware configuration file
so-called hardware profile refers tell Windows which devices when you start your computer, as well as a series of instructions which settings to use for each device should start. When the user first installs Windows, the system automatically creates a hardware configuration file named “Profile 1”. By default, all the Windows installed in the “Profile 1” hardware configuration file are enabled on this computer. Device
From the "System Properties" "Hardware" dialog box, you can see that there is a "Hardware Profile" button, click to open the window shown, in the "Available Hardware Configuration" The list of hardware profiles available on the local computer is displayed in the Files list.
The role of the hardware configuration file
Load only the device driver in the hardware configuration file
Under "Available hardware configuration file", use the arrow button to use the default as required The set hardware profile is moved to the top of the list so that only the hardware devices enabled in the selected profile are loaded when Windows starts. Once the hardware configuration file is created, we can use Device Manager to disable and enable the device in the configuration file so that the device driver will not be loaded the next time the computer is started, thus increasing the system startup speed
Quickly switch between different working environments
As mentioned above, we can create multiple different hardware profiles at the same time to suit different working environments, just select "Wait for users" in the "Hardware Profile Selection" section. The "Select hardware configuration file" item can be used. When the computer is started later, a "Hardware configuration file" selection menu similar to the multi-boot menu will appear, and then different working environments can be switched at will.
For laptop users, the hardware configuration file will be very useful, because most laptops are used in mobile situations when users move the laptop from one place to another. The hardware configuration file allows the user to change the device used by the computer. For example, we can create multiple hardware profiles for different occasions, which is very convenient to switch.
Increase startup speed
If you have not created multiple different hardware profiles, or you want to automatically load the default hardware configuration file during startup without displaying list items, then please Enter "0" in "Seconds" in the Profile Selection section. Of course, even if you still select a different hardware profile from the list, just press and hold the space bar at startup to display the list
Restore default configuration
If the hardware changes exceed a certain limit Windows XP may require the user to reactivate the system, which is very cumbersome. However, if we backed up the original hardware configuration file each time we installed or changed the hardware, just click the "Copy" button from the Figure 1 window and type a new one in the "Copy Configuration File" dialog box as shown. The file name is OK. When there is a problem in the future, you can re-import the previously backed up hardware configuration file.
It should be noted that the above operation must be logged in as the system administrator.
clear the system redundant hardware information
if for some need, you often go to plug hardware devices, repeat the installation process so that drivers will be left behind in the system a lot of hardware registration information system When starting up, it will repeatedly communicate with these non-existent devices, which will slow down the system. How to clear these redundant hardware information?
Very simple, we can delete the "Profile 1" hardware configuration file, and then re-create a new hardware file, this is the new system. To be on the safe side, don't delete it right away. Click the "Copy" button to back up (Profile 2), then rename it, for example to "Profile", then restart the computer. The following prompt will appear: < BR>
Windows Cannot determine what configuration your computer is in select one of the following:
1.Profile
2.Profile 2
3.None of the Above
Here the "1" and "2" are the hardware configuration files that already exist in the system. Of course, we choose "3", so that Windows can re-detect the hardware, and the screen will appear " "Detect hardware" dialog box, and prompts "When you start the computer with the new configuration, Windows must make some adjustments. This process takes about a few minutes", the "Configuration Settings" dialog box will appear later, prompting " Windows has successfully set up the configuration of the new computer, its name is Profile 1", click the "OK" button, and then you can reinstall the driver of the hardware device
Note that after rebooting the system, remember to delete the two hardware configuration files except Profile 1, otherwise you will still be asked which configuration file to use when booting.
