BTW, i guess the RBT lib is a kind of linked list api. Do you have some documentation on it,...? :)
RBT = Read-Black tree. There is no documentation - I think the definitions and the function names speak for them self :-D
(I currently can't find the C Code that I've used for translation, but it is all based on algorithms that can be found in the book "Introduction to Algorithms; MIT Press".)

Unfortunately it didn't find the desktop for all processes (even with Admin rights).

I guess that desktop name is there only when the application has a window( or hook, ...) on the desktop. I still need to compare the results with your code, but have some questions there, only am trying to find out as much as i can before i start asking questions...

SystemHandleInformation etc isn't very documented in the msdn , are those documented in the "DDK/WDK"?

Did you update the code? Something important?

Not important to the functionality of the program, but I've made some changes to rbt.lib. I've also add some comments in rbt.inc.

Also take a look at this page: HOWTO: Enumerate handles

Whatever he will do it, the fun will begin when he recognize that it is dam hard (at least for Win7/Vista) to close/remove a desktop without rebooting or closing the curent session:  Windows,  AVs and other software may create processes for that desktop. Because they keep handles to the desktop, it required to find and kill them...

Just curious: Why should that be such a big problem? Normally, you don't create the desktop with the intention to close it soon after... just leave it running.

The problem is to remove it, when it is no longer needed ;)
