Using the File-Based Write Filter configuration interface

In addition to the DOS command-line tool, Windows Embedded includes a FBWF configuration

interface. You can access the FBWF interface by using the Windows Control Panel.

To access the FBWF interface, follow these steps:

1. Log on as an administrator.

2. Select Start > Control Panel.

3. Select HP WriteFilter Configuration.

The FBWF interface includes the following buttons:

● Enable/Disable Write Filter

Enable/disable the FBWF so that data written to the protected media is cached or not.

●

Enable/Disable Cache Compression

Enable/disable cache compression.

● Enable/Disable Cache Pre-allocation

Enable/disable cache pre-allocation.

● Set Cache Threshold

Set the amount of RAM in MB that the FBWF cache can use.

Using the File-Based Write Filter status utility

The FBWF status utility creates an icon in the notification area of the taskbar that shows the status of

the FBWF. You can right-click the icon to display and execute the available options.

The FBWF Status icon displays the following states:

●

Red lock: FBWF is disabled.

● Green lock: FBWF is enabled.

●

Yellow lock: FBWF state will change on next boot.

If you are logged on as an administrator, you can change the status of FBWF by right-clicking the

icon and selecting the desired FBWF state.

NOTE: Because the fbwfmgr.exe utility and the FBWF status service execute separate code, status

changes made by fbwfmgr.exe are not automatically reflected by the FBWF status icon.
