Save and configure system hardware registration information-12 full guide to registry usage

The computer has been in use for a long time. I often need to replace some hardware devices and reinstall the driver.ProgramAs a result, there is a lot of hardware registration information left in the computer. When the system starts, it will try to communicate with non-existent devices, leading to a decrease in the system speed. How can I delete the registration information? Formatting? Too much trouble!

In fact, Windows has a "hardware configuration file" function, which is used to tell the computer which hardware devices are started at startup. When Windows is installed for the first time, by default, the system creates a configuration file "original configuration" (profile1 in Windows 2000 and Windows XP ). We just need to delete it and create a new configuration file. Isn't there a new Windows Hardware configuration file? Come with me:

1. Choose Start> Settings> Control Panel> system> hardware configuration file, or right-click on my computer and choose Properties> hardware configuration file ", you will see the configuration file original configuration;

2. Select it and click "RENAME" to give it a new name, such as "Peizhi ";

3. Select "Peizhi" and click "copy". In the displayed dialog box, enter the name of the backup file, for example, "peizhi2". Click "OK" and restart the computer;

4. This boot will not directly go to Windows. Instead, the following prompt appears, asking you to select which hardware configuration file to use.

Windows cannot determine what configuration your computer is in. select one of the following:

1. Peizhi

2. peizhi2

3. None of the above

Among them, "1" and "2" are existing configuration files in the system, "3" is to allow the system to re-detect the hardware, here you must select "3" for the system to re-detect the hardware. In this case, the "check hardware" dialog box appears, prompting "the first time you start your computer with a new configuration, windows must make some adjustments. This process takes about several minutes ";

5. After confirmation, the "configuration settings" dialog box appears, prompting "Windows has successfully configured the new computer, and its name is original configuration". After "OK, after the hardware device is installed automatically or manually in the normal way, the system requires that the computer be restarted. After the hardware configuration file is restarted, it is created;

6. Right-click my computer and choose Properties> hardware configuration file ", the deletion of two configuration files except "original configuration" will result in the success. (Note that you must delete them here. Otherwise, you will be asked which configuration file you are using when you start the system ).
