Windows To Go is an enterprise feature of Windows® 8 that enables the creation of a Windows To Go workspace that can be booted from a USB-connected external drive on PCs that meet the Windows 7 or Windows 8 certification requirements, regardless of the operating system running on the PC. Windows To Go workspaces can use the same image enterprises use for their desktops and laptops and can be managed the same way. Windows To Go is not intended to replace desktops, laptops or supplant other mobility offerings. Rather, it provides support for efficient use of resources for alternative workplace scenarios.
