Hanzac already released a 64-bit Windows build based on my GitHub repository about 2 weeks ago after I fixed the checkpoint warning. Multiple people have checked it out and haven't observed it to do anything suspicious or unusual: https://bitcointalk.org/index.php?topic=206577.msg2207446#msg2207446
Yea, I even sent him a question or two. I was already working on it when I saw that. I was also trying to enable all the options on Windows, qrencode was the only one I couldn't get going. *shrug*
