This script adds specified programs to the Windows Firewall exceptions list. To perform this task, it uses the Windows Firewall COM automation server. It runs only against the local computer.

OpenPrograms-com.vbs corresponds to OpenProgram.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 OpenPrograms-com.vbs. To run the script, open a command prompt window to the directory of the script and type:

cscript openprograms-com.vbs

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