This script runs against multiple computers to disable a specific Internet Explorer add-on. It makes this change 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.

Addon-wmi-multi.vbs corresponds to AddOn.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:

Input for this script comes from a text file, addon-hosts.txt, which contains the names of computers against which the script will run.

Each line of the input file must contain the name of a computer. Each computer must be accessible on the network and the credentials under which the script is run must have administrative privileges on it. For example:


Be sure there is no line break after the final line, as this will be interpreted by the script as an empty string.

To use the script, copy the code, paste it into Notepad, and then save the script as addon-wmi-multi.vbs. Then create a text file with the name of a computer on each line, as described above, and save it as addon-hosts.txt in the same directory as the script. To run the script, open a command prompt window to the directory of the script and type:

cscript addon-wmi-multi.vbs

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