Creating a Portable Windows 10 Environment with Windows To Go

You can use Windows To Go, a feature in Windows 10 Enterprise (and previous versions), to provision a USB drive with a complete and managed Windows 10 system image. You can insert the USB drive (known as a Windows To Go workspace) into a managed or unmanaged Windows 10 host computer to boot and run a managed Windows 10 system. You don’t have to install any software on the host computer to use the Windows To Go workspace.
