I am concerned that when you leave your computers on; do you leave them on all of the time or just when you are doing an update. Doing this consumes a ton of power, ac, not to mention security issues..

Let me fix the issue.. abandon the pc on the desktop and give everyone a dumb terminal that connects to a server. Do any updates to the test server and and test the updates; that's what the T&D systems are for.

I cannot think of one instance where anyone would need a PC at their desk anymore. There is no complelling argument that would convince me otherwise.
