A good idea it is, but it doesn't seem so easy.

In WPKG Client, we managed to:
- display a window with custom messages on shutdown (like a logon delay 
window now)
- delay a shutdown

Unfortunately, we fail to:
- establish new network connections when the machine shuts down
- execute new tasks as a specified user (Administrator, domain 
Administrator)
- even when we start "cscript ...\wpkg.js" as a SYSTEM user, it ends 
with an unknown exit code

:(


So most likely, executing on shutdown will not be possible to initiate 
from within the WPKG Client.

It is possible to execute tasks on shutdown using GPO - network still 
works fine then - but there seems to be no API to add/change new tasks 
reliably (some "reverse engineering" shows that something has to be 
added to the registry here, something has to be added to the registry 
there, a file here etc.), not to say to schedule a maximum execution 
time. And if there are existing tasks already, it gets even more messy.


So unless there is a great Windows guru out there willing to help, we 
will only be able to schedule WPKG Client to start its tasks on Windows 
startup (as we do it right now).
We could also add something like "try to connect for X minutes", as a 
workaround for (mainly) laptops which establish a network connection 
only when the user logs in.
