• Support for creating VHD-based/VHDX-based Windows To Go Workspace.

Please note: Windows 7/2008 R2 does not have built-in USB 3.0 support, so Windows 7/2008 R2 will have to be booted from a USB 2.0 port. Windows 7/2008 R2 is not completely portable. You may have activation and driver problems when booting on different computers. You need to be an administrator on the computer you are installing the WinToUSB on.
