EWF Modes (Standard 7 SP1)
There are two different modes of EWF based on the implementation of the EWF volume. EWF stores the overlay data in RAM. The EWF volume can exist in unpartitioned space on the media, or within the system registry. For more information, see EWF Overview.
Select the mode of the EWF overlay when you configure the Enhanced Write Filter with HORM settings. EWF RAM Reg mode requires additional configuration settings after you deploy the run-time image.
