Greg,

I did not quite get what your requirement is. Do you just want to launch your shell app and know when user input is available in it?
Then you should look at WaitForInputIdle API. You may end up launching a very small app as your shell. The app will run your heavy
shell through CreateProcess and during the launching time it may show a splash screen. If you call to WaitForInputIdle with the
handle from CreateProcess, then you know for sure when user is able to do anything within the shell UI.
More detail, " ... the calling thread can use the WaitForInputIdle function to wait until the new process has finished its
initialization and is waiting for user input with no input pending. This can be useful for synchronization between parent and child
processes, because CreateProcess returns without waiting for the new process to finish its initialization. For example, the creating
process would use WaitForInputIdle before trying to find a window associated with the new process.".
