Hello everybody

I'm new here. I am responsible for a Windows 2000 environment with over 10,000 users on a forest with 6 domains and about 40 installation points (locations where I store the MSI files). I'm looking for a program or a script that delivered an overview of all (software) and the GPO linked MSI files.
The intention with this information is to delete unnecessary and old files MSI.

Thanks in advance

Regards Pandit
