If you use the command line to modify the FBWF, right-click the icon to refresh the status icon display
(click anywhere on the screen to close the context menu). The status icon display is refreshed
automatically when you make modifications through the FBWF Control Panel utility. The FBWF utility
always reflects the current status.

Enhanced Write Filter

The Enhanced Write Filter (EWF) provides a secure environment for your computer by protecting it
from undesired flash memory writes (the operating system and functional software components
reside in flash memory). The write filter also extends the life of the computer by preventing excessive
flash write activity. Instead of allowing writes directly to the flash memory, it intercepts all flash writes
and caches them.

To save changes to system configuration settings, you must disable the write filter cache or perform
the 

-commit

 command during the current boot session. Otherwise, the new settings will be lost when

the computer is shut down or restarted. If you do not want to make permanent changes, you can
enable the write filter.

The write filter cache contents are not lost when you log off and on again (as the same or different
user). You can disable the write filter cache after the new logon and still retain the changes.

After you disable the write filter, all future writes during the current boot session are written to the
flash with no further caching until the computer is restarted. You can also enable/disable the write
filter by using the command line.

NOTE:

Only an account with administrator privileges can enable, disable, or commit the enhanced

write filter.

NOTE:

Always enable the write filter after you have made all of your permanent changes.

Using the Enhanced Write Filter command line utility

CAUTION:

When using the 

-commit

 command, all of the temporary contents are permanently

written to the flash memory.

NOTE:

Because the Enhanced Write Filter commands are executed on the next boot, you must

restart the computer for the command to take effect.

Windows Embedded includes the EWF command line utility. This utility enables you to issue a set of
commands to the EWF driver, report the status of each protected volume overlay, and report the
format of the overall EWF configurations.

By including the EWF configuration interface in your configuration and building it into your image, you
enable use of the EWF command line utility and the corresponding commands.

To use the EWF command line utility, follow these steps:

1.
