Interested in WDM

My company is looking to purchase WDM since we use roughly 300 Wyse S10 terminals through out our organization.

Our biggest issue is when they go to shutdown they accidently click "Reset the system setting to factory default". If this happens will WDM be able to connect to the device? And if you know of a way to disable that box please tell me!

Other than that the only time we need to make changes to the terminals is f someone needs a different printer for some reason. I'm sure WDM can manage that.
