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.

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 the blank windows, such as the blank Operation Panel of the search assistant of the 'search' function of XP, the blank System Restore page, and the blank User Account page (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.
