Under XP it wasn't possible for a service to launch a program in the local session, but it was possible to call things such as LockWorkstation, and play sounds. Now with Windows 7's full session 0 isolation, these things are no longer possible. It also is no longer possible to listen for the user session switch event.

Everything I've read on the internet says no, but I figured I'd ask here...

Is it possible do the following things as a service in Windows 7:

• Execute a program in a user session
• Play sounds out of the local sound card
• Detect user session switch

For the time being, I've moved any code for these items to my client application which communicates with my service. I would like to get these things working in the service though, if at all possible.

It seems backwards to me that a service installed with elevated permissions cannot gain control or execute on a session with lesser privileges.
