UnRegister DLLs
You can use the Regsvr32 tool (Regsvr32.exe) to register and unregister object linking and embedding (OLE) controls such as dynamic-link library (DLL) or ActiveX Controls (OCX) files that are self-registerable.

RegSvr32.exe has the following command-line options:

Regsvr32 [/u] [/n] [/i[:cmdline]] dllname

/u - Unregister server<BR/>
/i - Call DllInstall passing it an optional [cmdline]; when used with /u calls dll uninstall
/n - do not call DllRegisterServer; this option must be used with /i

When you use Regsvr32.exe, it attempts to load the component and call its DLLSelfRegister function. If this attempt is successful, Regsvr32.exe displays a dialog indicating success. If the attempt is unsuccessful, Regsvr32.exe returns an error message, which may include a Win32 error code.

Example: To unregister Winshow's winshow.dll:
