I am trying to send a message from my Win XP Pro 32 bit machine to my Win 7 Pro 64 bit machine. However Interactive Services Detection is holding up the message until I respond to a prompt (something like "Do you want to view the message?"). I know how to disable Interactive Services Detection, but when I do, I don't receive the message at all. Is there a way to receive the intended message, but without the Interactive Services Detection prompt?

No, sending message from Session 0 (Services Session) to the Desktop session (1 for the first user) doesn't work. This feature is called Session 0 Isolation and was added with Windows Vista: Session 0 Isolation Application Compatibility: Session 0 Isolation Impact of Session 0 Isolation on Services and Drivers in Windows"A programmer is just a tool which converts caffeine into code" CLIP- Stellvertreter http://www.winvistaside.de/
