Big agencies with many Windows workstations already use Microsoft SMS or System Center (I believe that's what its called now) to deploy software over the network. How do you differentiate?
With SMS or System Center you have to create the packages yourself and/or have a system in place to fetch the latest packages.
Upgrading 7-zip [first entry on your screenshot] isn't compulsory. If you do upgrade, you take a risk that there will be no adverse effect.
Older software is usually vetted and proven functional in the particular corporate environment where it's deployed, doesn't conflict with other software, etc. My friends in corporate world have told me how it takes X many months for upgrades to be rolled out because they must be tested in sandboxes first to make sure nothing explodes unexpectedly.
This apparently applies to all software, from OS updates down to individual program updates.
I am curious because your comments, and the way they are worded make it sound like you are not from the US and you are young.
