   Windows Home Device Encryption when enabled   
     - first looks to store the key in the MSFT account that was initially   
   used to setup(first use) the device even if that MSFT account was   
   switched to a local logon. If not setup with a MSFT account or MSFT   
   account no longer present on device, the only options for the user to   
   obtain the key are - Save to USB, copy to paper, copy and save to text file.   
     - the key itself for validation purposes is stored on the device, but   
   not in readable or accessible form.
