Exe installers support unattended, headless installs with a command line switch.

But how you do run that command only once on every computer? Including ones that are currently not in the building, or on.

Same way as anything, use group policy or a login script that checks first.

But how do you know if it's installed correctly?

[mixmastamyk]

What does correctly mean? On windows usually a registry key is checked.

Exactly, changes from software to software. And how to uninstall?

Much easier to add an MSI to GPO, and then just as easy to remove it again and it's uninstalled.

Not sure how writing scripts to do all that myself for every piece of software is better.
