You can use Enhanced Write Filter (EWF) to enable a Hibernate Once/Resume Many (HORM) environment. By using an EWF-protected hibernation file, you can save the state of a system. Applications and services are running when the system starts, and start time is quicker. By saving the state of a system to a hibernation file, you can continually start from that hibernation file. This enables you to preserve state across multiple restarts.

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

To configure a HORM run-time image, follow these steps.
