I've used this USB Installer to create bootable USB installation media for Win7 Home, Win7 64 Home, Win8 RTM, and Win8-64 RTM, worked great everytime. You do need to download the Windows 7 USB/DVD Download Tool from MS to make it work. And I have used it for several Linux distros as well. A fantastic tool for those who like to play with a different OS every day.
