Login screen of last user and running a command

[balubeto]

Hi

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.

Thanks

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.

Thanks

Bye
