Being able to run your own version of Windows, no matter what computer you're currently on and without having to wait to install it, can be quite important. WinToUSB is an application that can help you with that.
WinToUSB is a tool that can create portable versions of Windows, which you can run from a USB device. In order to create the portable version you can use an ISO image or a DVD installation kit. Furthermore, you can also clone your current operating system.
What I like about WinToUSB is that the application is amazingly easy to use, so even if the task itself may seem complicated at first, it can be done even by those less tech-savvy. As far as disadvantages go, I thought that the cloning speed was a bit slow in the free version, but if you opt for one of the paid versions it gets better.
As far as I'm concerned, WinToUSB is an application that is actually worth using if you ever need to make a portable Windows version. However, unless you are trying to clone Windows 7, I would recommend using a USB 3.0 device so that you won't have a very long time until the bootable version loads.
