Great, the best way to start is to watch qemu-devel and kvm mailing
lists for Windows-related questions.  The bug tracker automatically
sends notifications to the mailing list so you'll also see new bugs.

Perhaps you want to look into the bug I linked in my previous email.
Several users have reported the problem and it would be great to fix
it:

The 0.2 is someone who is not working full-time on virtio Windows
drivers.  They have other responsibilities too.
