system which run under spooler service.

Sounds like a job for WTSEnumerateProcesses() ?

A quick trawl on Google, shows this sample:

But you are always going to find it awkward to send WM messages from a
driver or service, to a user session. Basically Microsoft does not want you
to do this; so they don't provide any APIs to make it easy. The robust way
for a service to communicate with a user, is to have a user mode process
which starts when the user logs in (it could be a hidden app, no visible
Windows). This app displays the messages to the user, eg via MessageBox().
The driver and/or service communicate with this user-mode app, using some
proper form of inter-process communication, such as Named Pipes or RPC -
instead of trying to poke a WM message across session and user boundaries.
Sending Window Messages like that worked back in simple Win 3.x days, when
no-one cared about security, and there was only a single user per machine.
But it just doesn't fit in with today's world. You've already seen thsi
page, right?

Hope it helps a bit,

By the way, while I think your question *is* appropriate for this newsgroup,
you'll probably get better answers at a forum like Code Guru:
http://www.codeguru.com/forum/

.... or The Code Project:
http://www.codeproject.com/script/comments/forums.asp?forumid=1647

.... or the "microsoft.public.win32.programmer.ui" newsgroup.

I don't think many of the folks reading
microsoft.public.windows.vista.general are Win32 C++ programmers! Most of
them are just users. You'll get better answers for these questions from
places where programmers hang out.

Good luck!
Andrew
