Shutdown Screen

[Amir Ahani]

Hello,

I'm developing an Embedded Windows XP industrial system which we wish to
install on heavy-duty machines.
My questions:
1) I want to modify the windows shutdown screen and replace it with another
bitmap.
What should I do? I checked a variety of software such as BootXP, Inno Logo
and Resource Hacker, but they are only useful for modifying the windows boot
screen.
(I know that for modifying the windows boot screen and logon screen, we
should modify the ntoskrnl.dll and msgina.dll, but I didn't find anything
about shutdown screens)
2) We are working with real-time systems and for our measurements, we need
to know which is the interrupt to task execution? I know that Venturcom Inc.
has RTX (real-time extension) with worst case values typically under 40 µs,
but if we connect hardware to our XPE system for controlling purposes
WITHOUT using the RTX extension, can we say that XPE is real-time or not? If
YES, please inform us of the worst case delay or response time?

Read your license agreement. This is illegal to do.

You can prevent logos from showing.
In boot.ini use switch /noguiboot
And if you use minlogon, you won't have shutdown screen.

There is probably way to stop it from showing in winlogon, but I have never
needed it.

Best regards,
Slobodan

Hi Slobodan,

I tried your suggestion before but something funny happened, we are using
special UPS which we control it programmatically so we call some API
functions to shutdown the windows and UPS.
What would happen when we use this approach?
MinLogon did not show anything and it seems that there is no shutdown screen
but after we run our shutdown procedure which is simply calling SHUTDOWN API
and talking directly with our ups ports, the shutdown screen again appears
and we couldn't get rid of that.
The reason that we persisted to eliminate it is for our novel real-time
product that we do not want to have shutdown screen.

Sorry, then

I don't have shutdown screen with my minlogon.
I'm using ExitWindowsEx for shutdown.

Someone else could know what is the problem.
