@4.: What I meant was direct communication between a service and an interactive application. Some time ago, services lost the ability to directly manipulate windows on interactive desktops (should be since XP, if the service was configured appropriately), but I consider starting an interactive application in a user context basically the same and won't be surprised if that can't be done anymore in the future. Indirect communication like
TCP/
IP or pipes should always be available, but in my opinion a service should not be able to start or manipulate a user application. If the service needs to communicate with the user, maybe it should not have been a service in the first place. But as repeatedly said, that's just my opinion on consequently restricting
access and I'm just curious and like to hear why it should stay the way it is.
