Windows 8.1 running off of a USB flash drive!

Here is a full version of Windows 8.1 Pro running off of a USB flash drive like it is a hard drive! I used a program called WinToUSB to install Windows to the flash drive! WinToUSB download: http://www.easyuefi.com/wintousb/ You need at least a 16GB flash drive for it to work properly!
