Customize "Logoff" button action

Hey,

I've looked all over the internet for about 2,5 days, but no succesful
answer:

Is there any possible way to change the action behind the "Logoff"
button?

We have to do this because we are serving serveral virtual windows XP
desktops;

Users connect to the desktop using RDP, so, there is the "Shut down"
button not available.

We want, when a user logs off the virtual machine, that the machine
logs off and restart again. (to remove changes to the drive using
Steady State).

We have tried to do this with a logoff script, but that is not working
(the shutdown -r -t 00 process is killed by the logoff process.)

Thanks,

The commands are hard coded inside
\WINDOWS\System32\user32.dll

To change the action when pressing the Log Off button you need to find
the code inside of user32.dll and change it.

ExitWindowsEx(int uFlags, int dwReason)

Log Off: ExitWindowsEx(0, 0)
Log Off: ExitWindowsEx(4, 0) (force processes to terminate while
logging off)
Reboot: ExitWindowsEx(2, 0)
Shutdown: ExitWindowsEx(1, 0)

This is a fun challenge, if you need more info tell me where to start.
Do you know how to mod a dll, etc.?

Thanks,
but, is this supported by Microsoft?

Are there some alternatives?

With regards,

You could create a shortcut on the desktop to the shutdown.exe file and
modify the paramaters used in the target box on the general properties page
of the shortcut. I used to use this trick to force an older machine I had
installed XP on to shutdown at a specified time. HTH

>>is this supported by Microsoft?

Of course not.


>> Are there some alternatives?

Good luck!

Modding the dll is the easiest way.

Just change ExitWindowsEx(0, 0) to ExitWindowsEx(2, 0)

I also have the need for a user to Reboot when the Logoff button is
press or selected, what do I use to edit the .dll? I can see the some
info with ResHacker but not the "ExitWindowsEx(0, 0)" I am trying to do
this on a Xp Pro box. Thanks for the Help!
