[wpkg-users] Running wpkg.js as System Account

- WPKG Client can run wpkg at shutdown.
- Scheduled tasks even for the System account can be created remotely
without the need for psexec. See the schtasks command. (But note that
schtasks depends on system language and version.) This is how I trigger
wpkg (client) deployment remotely.
- Both scheduled tasks and wpkg client (the service) can be triggered
remotely (by schtasks or by sc).
Actually I use WPKG Client on the clients and a few CMD scripts on the

Some packages will be quite big and, as said before, WAN (understand "slow" interco network) links must have a random waiting time because if there are only 4 or 10 computer booting during a 15 minutes delay on a 4Mbits and there are 10 MB or more package deployed to thoses machines, the best way would be for me to not deploy at boot, but later cause as you said, deploying software when users are working won't slow down their computers thanks to its perf.

For my part, I won't force shutdown, but when I need it, I will add an install cmd in my packages using msg.exe telling the user to Reboot when he can to complete an update. (to run it periodically I thought about scheduled tasks. If I need to use scheduled tasks, why would I run a service wich will in return run a script whereas I can run that script directly ? in

>> - when the scheduled tasked is about to run wpkg, I would like it to wait for some random time between 1 and 30 minutes for instance so that the network is not overloaded. (I suppose this part will need little modifications of the wpkg.js script itself but seems to be a quite easy one)
