Hibernation and EWF (Standard 7 SP1)

7/8/2014

You can configure your run-time image to always start from a hibernation file by using Enhanced Write Filter (EWF). The following list shows the benefits of starting from a hibernation file:

  • Quicker start time
  • Ability to define the state of a system by starting with specific applications and services running
  • Support for Hibernate Once/Resume Many (HORM)

Because EWF starts after the hibernation file is loaded, you can successfully start from, and save to, a hibernation file.

A new feature in Windows Embedded Standard 7 enables computers with EWF enabled to use the standard hibernation feature without activating HORM. To use the standard hibernate and resume features, you must ensure that HORM is deactivated.
