libvirt users - May 2015 - Shutdown Windows Server 2012 acpi

Hi,

I've got a virtual Windows server 2012 R2 running on lib-virt and qemu.
I've enabled acpi in the VM settings and edited following registry keys:

HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System\Shutdownwithoutlogon
to 1
HKLM\Microsoft\Windows NT\CurrentVersion\Windows\ShutdownWarningDialogTimeout to
10

This worked fine until there was a second user that loged in through mstsc and
didn't log off.

Looking on forums and blogs I couldn't find a solution for this.

Any help would be appreciated...

Greetings,

Dominique.
