This script turns on or off local machine lockdown for the iexplore.exe process by editing the registry, using the WMI System Registry provider. You must edit the registry path to insert the correct CLSID of the add-on component to be disabled. To identify the CLSID of an add-on component, search the registry for the add-on name that is located in the Manage Add-ons interface.

LocalMachineLockdown-wmi.vbs corresponds to LocalMachineLockdown.vbs, one of the scripts that ships with Application Compatibility Testing and Mitigation Guide for Windows XP Service Pack 2 and which are documented in the Appendix. You can download a Windows Installer (.msi) file that installs the Guide and its associated scripts from:


To use the script, copy the code, paste it into Notepad, and then save the script as LocalMachineLockdown-wmi.vbs. To run the script, open a command prompt window to the directory of the script and type:

cscript localmachinelockdown-wmi.vbs

If the default script host on the computer is Cscript.exe, the initial "cscript" may be omitted.
