In the XP system, some services not only occupy serious system resources, but also have poor functions and capabilities. It is not as convenient as some professional software. For example, its image preview and zip compression functions. In this case, we can use regsvr32.exe to uninstall these chicken ribs. Start -- run --- enter regsvr32.exe/u zipfldr. DLL to uninstall the function. If you need this function later, you only need to enter regsvr32 zipfldr. dll again. In the same example, you can uninstall the image preview function by running the command-run ---input regsvr32.exe/u thumbvw. dll. Enter regsvr32 thumbvw. dll when recovery is required.

　　

4. New methods to prevent web script viruses

The web script virus will become invisible when you browse the Web page. This virus is sometimes not found in general anti-virus software. In fact, this virus often calls the FSO object (File System Object ). Therefore, we only need to disable FSO to effectively prevent the spread of the virus. The operation method is also very simple. Start-run -- enter regsvr32.exe/u scrrun. DLL to disable FSO. Enter regsvr32.exe scrrun. dll in the dig command. I believe many others. I have some knowledge about regsvr32.exe. In fact, this command is the registration and anti-registration tool for control files (. dll,. ocx,. Cpl extension) in windows. The command is located in/Windows/system under Win98. In fact, in general, the so-called registration is to put some control files in the location where they should be (not strictly speaking ). However, it is much easier to use some system controls or other commands. For details about the parameters of this command, refer to the first figure in this post. Generally, only the/u parameter is used.

6. Enable WMP player to support RM format

Many friends like to use Windows Media Player (WMP), but it does not support the RM format. Do you have to install other playing software? Take Win XP as an example. First download a plug-in RM format and decompress the plug-in to obtain two folders: release (for Windows 9x) and release Unicode (for Windows 2000/XP ); in the release Unicode folder

Copy the realmediasplitter. Ax file to the "system drive letter/Windows/system32/" directory, type "regsvr32 realmediasplitter. Ax" in "Start> Run", and click "OK. Download the decoder, such as real alternative. After installation, you can use WMP to play the RM format audio and video files.

Some music Web pages use Media Player for online karaoke. Some friends have installed wmp9, but they only see the boring wmp6 player panel when they listen to music online. They want to make the beautiful wmp9 Panel appear, of course it's okay. For most Windows 98 operating systems with Frequently Asked Questions, close Ie first, type "regsvr32 wmpdxm. dll" in "Start> Run", and click "OK.

　　

8. Solve the Problem of no response when the system function is enabled

　　

Regsvr32 shdocvw. dll

Sometimes, you can click the search function, help, support, or management tools of the XP system from the Start menu, but there is no response, which is the lack of association in their opening method, so we only need to use regsvr32 to register the dynamic connection library files they need to call.

　　

9. The Add/delete program cannot be opened.

When you open the Add/delete program in the control panel, double-click its icon and there is no response, or automatically close it after it is opened. Try the following command to solve the problem.

Regsvr32 mshtml. dll

Regsvr32 jscript. dll

Regsvr32 MSI. dll

Regsvr32 "C:/program files/common files/system/ole db/oledb32.dll"

Regsvr32 "C:/program files/common files/system/ADO/msado15.dll"

Regsvr32 mshtmled. dll

10. XP user account cannot be opened

　　

　　

Regsvr32 nusrmgr. CPL

Regsvr32 mshtml. dll

Regsvr32 jscript. dll

Regsvr32/I shdocvw. dll

　　

11. Solve the problem that Windows cannot be upgraded online

Regsvr32 wupdinfo. dll although the two commands can be repaired, but the symptoms do not cure the problem. I suggest a friend who has encountered this problem go to the Microsoft website to perform IE security updates, that is, install vulnerability patches.

Regsvr32 jscript. dll

Regsvr32 VBScript. dll

It can effectively solve the problem that some web pages cannot be normally displayed and the function is not normal. Fix some blank windows, such as the blank search assistant operation panel, blank System Restore page, and blank User Account page of XP's 'search' function (100% degree of control can be fixed ). When Windows Media Player 9 or a later version is enabled, the system prompts 'internal application error' (100% degree of certainty can be fixed ). You can fix the blank space after 'add/delete project' of Win 2000 is opened (99% degree of control can be fixed ). Solve the problem that Windows 2000 does not see any files when viewing the Program Files folder and WinNT folder on the web, and the icon of the 'Control panel 'runs to the left. Solve the problem that the shortcut menu function of the Internet Express cannot be used on the webpage. On the website, When you right-click a 'Download connection', a menu will pop up. If you select 'use Internet Express downloading', The flashget download task page will pop up. If you find this function does not respond, this may be the reason: the original menu is the jc_link.htm file in the flashgetdirectory. This file is written in VB language, so its function is to lose the dynamic Connection Library VBScript. DLL is not registered or called. And so on.

Regsvr32.exe error message

The following lists regsvr32 error messages and possible causes.

Unrecognized flag:/invalid_flag

The keysign or switch combination is ineffective (see "regsvr32.exe usage" in this document ).

The dllname may not be exported, or the memory may have a corrupted dllname version. Consider using pview to detect the file and delete it.

Dllname is not self-registerable or a specified upted version is in memory.

For example, if you type regsvr32 icwdial. dll, the error message is returned because the icwdial. dll file cannot be registered by yourself. If you suspect a corrupted dllname version exists in the memory, try restarting the computer or re-extracting the original version of the file. If you are running Windows NT, you may need to use the kill or pview tool in the Microsoft Windows NT Server 4.0 Resource Kit.

Oleinitialize failed (or oleuninitialize failed ).

Regsvr32 must initialize the com library before calling the required com library function and uninitializing the library when it is disabled. If the attempt to initialize or uninitialize the com library fails, these error messages will appear. For example, the ole32.dll file may be corrupted or its version is incorrect.

Regsvr32.exe depends on kernel32.dll, user32.dll, and ole32.dll files (in Windows NT, it also depends on msvcrt. dll and advapi32.dll files ).
