If you are able to install the qemu-agent guest agent into your Windows guest, then newer qemu and libvirt have an option to use the guest agent to trigger a shutdown in this situation. But without that, you are stuck with the fact that by default, Windows ignores APCI interrupts when locked. There might be a registry setting you can tweak to make Windows behave differently than default, but offhand I don't know what it would be.
