Learn to use the Regsvr32 command in WinXP

In the Windows XP operating system, many system functions are related to controls (such as files with extensions DLL, OCX, CPL), and the controls must be registered to implement these corresponding functions. Normally, when the operating system is installed, the control will automatically register. However, due to virus damage, system failure or human cause during use, some control registration information is often lost, causing some functions of the system to malfunction. Once this happens, we can ask the Regsvr32 command to help resolve the registration of the control.

The Regsvr32 command is a utility provided by the Windows system that allows you to register or uninstall system controls to fix lost functionality. The Regsvr32 command runs as a command line. At the same time, the normal operation of the Regsvr32 command requires the support of Kernel32.dll, User32.dll and Ole32.dll files.

Tip: In Windows 2000/XP system, Regsvr32.exe command file is stored in the "X:\\Winnt\\system32" folder; in Windows 9X system, the command is stored in "X:\\Windows" In the \\system" folder (assuming the system is installed on the X drive).

The use of the Regsvr32 command is very simple. Let's take a look at a few examples to see how to use the Regsvr32 command to solve the actual problem encountered.

Example 1: Restoring Windows Xp Image Preview Function

In the process of using Windiws XP, if the image preview control registration information is lost, it will not be able to preview the picture properly. Since the control file corresponding to the image preview function of Windows XP is thurnbvw.dll, just click "Start/Run" in turn, enter "Regsvr32 Thurnbvw. dll" command in the pop-up "Run" dialog box, click "OK" "Button, after execution, a message prompt box will pop up: "DllRegisterServer in Thumbvw.dll succeeded.", the control registration is successful. After restarting the computer, the Windows XP image preview function will be restored.

Example 2: Restoring Zip function of Windows Xp

Windows XP system can directly support ZIP archives, although the function of processing Zip files is not powerful, but there is no professional solution installed. This feature is also convenient and practical when compressing software.

If the function does not work properly, you can execute the "Regsvr32 Zipfldr.dll" command in the "Run" box according to the example 1, and then restart the computer to recover. Conversely, if you need to uninstall the Zip function of Windows XP, just run "Regsvr32 /u Zipfldr.dll".

From the above two examples, we can see that the Regsvr32 command relies on parameters to register and unload controls. When registering, add the name of the control directly after the command, and when uninstalling, add "/u" to uninstall the installed control. Now let's take a look at the use of Regsvr32 commands in software applications.
