Application List

This script will generate a list of installed applications minus those in the exclusion list text file. I created this script so the help desk could have a concise list of applications that need to be installed post-build. The script excludes all apps that are in the exclusion list, which includes everything in our build. I wrote the script so that it can be executed from SCCM on a per system basis. It could be modified to allow it to execute on remote machines.

The first thing to do is to create the ExclusionList.txt file and place it in the same directory as the script. Next is create a package in SCCM. That is all that is to it.

You can download the script from here.
