Lets say to maintain a level of security on a windows system you need to make changes to the registry at every logon. Making the changes is easy (small c++ app called from logon script), however they dont seem to go into effect until the user logs off and back on to the system.

Is there a way to force the changes into effect immediately? Through the c++ app or other system command that can be called from the login script? One example would be the current wallpaper.

PS - I've been gone from the AO community for quite some time, it's good to be back!
