Microsoft introduced a feature called "Windows To Go" with Windows 8 Enterprise allowing to install Windows on a USB mass storage device similar to Linux Live distributions. The documentation supplied by Microsoft indicates that a volume licence is required and that a GUI tool exists to create the USB image.
On the web and here, users report that something equivalent can be achieved without an Enterprise volume license.
However this assumes that the user has install media or an iso-File, containing a file called install.wim. Preinstall OEM versions do not ship with media and neither the Windows partition nor the created recovery medium comes with a file install.wim.
How can you achieve "Windows To Go" with OEM versions?
