You want one copy of Windows that you can take it wherever you go, and use it on any computer that has a USB port? Follow the wizard to install a portable version of Window 8 on a USB hard drive that you can get anywhere.
The Enterprise Edition of Windows 8 has a feature called Windows To Go that allows you to install a portable version of Windows on a "certified" flash drive. Unfortunately, most of us do not have the Enterprise version of Windows 8, nor a certified flash drive. However, there is a tool called WinToUSB that does exactly the same thing. It does not matter which version of Windows you have WinToUSB he will do his job.
Note that the following procedure is different from installing Windows from a USB drive to install Windows on a computer that does not have a CD drive.
Below are the steps to install Windows 8 on a USB drive so you can run them on any computer, take it with you, use it for troubleshooting, and so on. A kind of live USB with Wwindows 8 that is.

A Window installation file or ISO image. We recommend that you use Windows 8. Windows 8 will allow you to use your portable installation on any computer, because Windows 7 does not work as well as a portable installation. They encounter driver-finding problems or activation problems if you use the same key on other computers.
A USB drive. An external hard drive is preferable to a flash drive, as it will run much faster. The USB 2.0 will be enough, but if you have USB 3.0, we recommend it.
The WinToUSB application. A simple free program that will guide you through the installation process.
We tested it using a Windows 8.1 ISO and a USB 2.0 external hard drive, and the results were quite satisfactory. The speed it gave us was quite satisfactory, and it installed the programs automatically driving that were needed. So far the USB has run successfully on 3 different computers.
