In Windows 8, it is possible to run a command whenever the login screen of the last user is displayed in a local computer? This command should always be run with elevated rights and just before this screen appears.
In other words, I should change the value of a registry entry via a reg command before the last user login screen appears. In addition, this reg command should be run whenever this event occurs regardless of the type of account and of the cause that produced it.
The TS listed "Windows 8" in his specs, so logoff scripts would be a very long shot. That's the reason I haven't mentioned it. But it doesn't look like the TS is interested in solving his problem anyway
