I have no idea why it is failing. Your screenshots look good other than the "failing" part.
Perhaps you have a "permissions" problem. Try running fastboot from an Administrator account on your windows machine... Or maybe you need to reinstall it as administrator. I turned off the ACL crap on my Win7...
