Hi Marc-André,

Thank you for taking the time to look at this!

I got it via www.spice-space.org which redirects to virt-manager.org for the Windows binaries. Here is the exact URL:
http://virt-manager.org/download/sources/virt-viewer/virt-viewer-x86-1.0.msi
But the URL on fedorahosted looks "visited" in my browser, so I think it is the exact same file.

I created an XML domain file and imported it via "virsh define". When I run vish dumpxml on the domain when running, this is what I get:

I can't find a more recent version of the official Windows client.

I did try a home-brew version of Fabiano Fidêncio from here: http://blog.fidencio.org/2014/11/virt-viewer-using-gtk3-for-windows.html but this also hides my Windows mouse pointer as soon as I enter the virt-viewer window.

I went through hell and back to compile the latest remote-viewer-1.0 from source on a Debian 7.7 machine, but when the mouse enters the remote-viewer window, the mouse leaves the building... :(

You are welcome. More accelerated stuff sounds good to me.
