“Disk Mode Write Filter” or “Resetting Differential VHDs”

The Enhanced Write Filter is also shipped with Windows Embedded Standard 7. However it does not include the Disk mode known from earlier Embedded versions. The Disk Mode allowed to save all the changes on a separate hard drive.

There is an alternative approach available to create a scenario similar to the EWFs Disk Mode – you can use VHDs.
