When EWF is enabled, the
C:
partition is protected from any disk writing.
In this mode, any changes on the
C:
partition (including modifications to
files or the registry) are redirected to memory. Thus, these changes are
discarded in the next system startup. You can enable this mode manually
after finishing all system changes such as installing your applications or
adjusting system settings.
HORM
Hibernate Once, Resume Many (HORM) enables users to create a single
hibernation file and boot to that file repeatedly. Using HORM, you can boot
to a known state each time the system is powered on. HORM works only
when EWF is enabled on all system partitions. HORM does not work with
FBWF. Depending on the system state, HORM can reduce boot times.
To enable HORM in Windows XP Embedded, you first must enable EWF
as described in the
EWF and FBWF
section. Once enabled, return to the
EWF utility at
Start»All Programs»Utilities»EWF
. Select the
HORM
tab and select
HORM
. This hibernates the system and creates the
hibernation file. After you perform this step, all subsequent reboots resume
from that hibernation file.
To enable HORM is in Windows Embedded Standard 7 (WES7), search for

Note
You can programmatically control EWF, FBWF, and HORM using VIs included
with the LabVIEW 2010 or later Touch Panel Module.
