In Windows XP and Windows 8 you will see what software is being installed via GPO at start or login. In Windows 7 this has been shut off as standard. To enable this behavior do the following.
Open up GPMC and create a new group policy.
Computer Configuration\Policies\Administrative Templates\System
The policy is called on Windows Server 2008 R2:
“Verbose vs normal status messages” = Enabled
The policy may also be called on Windows Server 2012 + 2012 R2:
“Display highly detailed status messages” = Enabled
Enable it and you’re done.
