Hibernation and EWF
You can configure your run-time image to boot from a hibernation file with Enhanced Write Filter (EWF) enabled. The following list shows the benefits of booting from a hibernation file:
- Quicker boot time
- Ability to define the state of a system by booting with specific applications and services running
- Support for Hibernate Once/Resume Many
Because EWF starts after the hibernation file is loaded, you can successfully boot from, and save to, a hibernation file.
Note Use of EWF with hibernation is supported only in RAM modes.
