Question : Applying Group Policies at any point of time

I have an installer package which I am deploying on the network using group policies. It gets properly installed on the network machine when that machine is started/logged in.

Can I install (by running the group policy) it at any point of time? What I mean is, the software should get installed in the background while the user is logged in!!!

Answer : Applying Group Policies at any point of time

Some group policies - including software installation are only applied at logon/logoff or at startup/shutdown.
