I know. I treid to implement the multiple desktops using this functions,
(thats's what I called "true desktops") but had to see it isn't possible to
get
it right this way. If you want, you can look into my explorer source code.
It's still there - just disabled. Using CreateDesktop() and SwitchDesktop()
shows the following problems:
- It's not possible to share the notification area among different desktops.
- If you want to launch programs from those additional desktops, it's not
enough to create a new thread per desktop, you have to launch an explicit
new explorer processes for each of the desktops.
- You can't (simply) move one application from one desktop to another.
(However it could be possible by using a thread-/DLL-injection technic,
I didn't try this.)

The XP powertoy desktop switcher also doesn't use this CreateDesktop()
API, it's also just hiding windows when switiching from one "desktop" to
another.
