I'm writing a co-installer for my driver and I need to broadcast a
private message to all running applications in the entry point. I use
the BroadcastSystemMessage api as below:

DWORD dwRecipients = BSM_APPLICATIONS | BSM_ALLDESKTOPS;
BroadcastSystemMessage(BSF_POSTMESSAGE | BSF_IGNORECURRENTTASK,
&dwRecipients,
g_uBroadcastMsgId,
1, 0);

But it seems not working in Vista. How should I do?
Any help will be appreciated.

I used the Spy++ tool to check applications, they never received the
message at all. But it's OK in WinXP.

In Vista, the coinstaller runs on another desktop and cannot access the UI
of the interactive apps.

Thanks! It's limitation of Vista, isn't it? Any solution for this
issue?

None I'm afraid of.

Why do you need this? What is the interest for _all_ applications about
your device being installed?
