Run Windows 8 or 8.1 directly from a USB drive on any computer — for free

The Enterprise edition of Windows 8.x has a feature called Windows To Go that lets you create a working version of Microsoft’s tiled operating system on a USB memory stick. You can boot into this and be instantly up and running in the new OS from any computer. Which is great — provided you have the Enterprise edition of the OS and a “certified” USB drive. If you only have the standard version of Windows 8.x then the option isn’t available to you.
