2 HP Write Filters

The File-Based Write Filter (FBWF) and the Enhanced Write Filter (EWF) provide two distinct ways to provide a secure environment for your computer by protecting it from unauthorized writes to storage and file systems. FBWF operates at the file level, and EWF operates at the sector level. Only one write filter can be selected and active at one time.

File-Based Write Filter

The File-Based Write Filter (FBWF) provides a secure environment for your computer by protecting it from undesired read and write access to write-sensitive or read-only storage.
FBWF has only two states, enabled or disabled. When FBWF is disabled, all previous changes are lost.

Using the File-Based Write Filter command line utility

Windows® Embedded includes the FBWF command line utility. This utility enables you to issue a set of commands to the FBWF driver, report the status of each protected overlay, and report the format of the overall FBWF configurations.
By including the FBWF configuration interface in your configuration and building it into your image, you enable use of the FBWF command line utility and the corresponding commands.
To use the FBWF command line utility, follow these steps:
1. Select Start > Run.
2. Type CMD in the Open field to access the system DOS prompt.
3. Click OK.
4. Type fbwfmgr c: at the prompt.
5. Press enter.
When you enter the fbwfmgr [boot command] syntax, use the following commands in the boot command variable of the command line:
/disable
Disables the write filter on the next restart.
/enable
Enables the write filter on the next restart.
File-Based Write Filter 3
/displayconfig
Displays all current configuration information for the write filter including filter state, protected volumes list, cache compression state, overlay cache threshold, cache pre-allocation status, and write through paths.
/overlaydetail
Displays detail on the current overlay contents for all protected volumes including file and folder contents and memory used.
/addexclusion
Adds a write through path to the exclusion list.
/removeexclusion
Removes a write through path from the exclusion list.
/setthreshold
Sets the overlay threshold value.

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 Write Filter 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.
4 Chapter 2 HP Write Filters
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.
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.
Enhanced Write Filter 5
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. Select Start > Run.
2. Type CMD in the Open field to access the system DOS prompt.
3. Click OK.
4. Type ewfmgr c: at the prompt.
5. Press enter.
When you enter the ewfmgr [boot command] syntax, use the following commands in the boot command variable of the command line:
-all
Displays information about all protected volumes and performs a command, such as disable, enable, and commit, on each volume, if specified.
-commit
Commits all current level data in the overlay to the protected volume, and resets the current overlay value to 1. You can combine -commit with the -disable command to commit and then disable.
-disable
Disables the overlay on the specified protected volume.
-enable
Enables the EWF so that data written to the protected media is cached in the overlays. The current overlay level becomes 1 as soon as EWF is started, and a new overlay is created at level 1.
-commitanddisable
Commits data in the overlay upon shutdown and disables EWF after the system reboots.

Using the Enhanced Write Filter configuration interface

In addition to the DOS command-line tool, Windows Embedded includes an EWF configuration interface. You can access the EWF interface by using the Windows Control Panel.
To access the EWF interface, follow these steps:
1. Log on as an administrator.
2. Select Start > Control Panel.
3. Select HP Write Filter Configuration.
6 Chapter 2 HP Write Filters
The EWF interface includes the following buttons:
Enable/Disable EWF
Enables the Enhanced Write Filter so that data written to the protected media is cached in the overlays. Disables the overlay on the specified protected volume.
Overlay Configuration
Displays the overlay information and is a combination of the information supplied when executing ewfmgr.exe c: -Description and ewfmgr.exe c: -Gauge from the DOS prompt.
Clear Boot Command
Clears the boot command from the DOS prompt.
Commit Data to Volume
Commits all current-level data in the overlay to the protected volume, and resets the current overlay value to 1.

Using the Enhanced Write Filter status utility

The EWF status utility creates an icon in the notification area of the taskbar that shows the status of the filter. You can right-click the icon to display and execute the available options.
The EWF Status icon displays the following states:
Red lock: EWF is disabled.
Green lock: EWF is enabled.
Yellow lock: EWF state will change on next boot.
If you are logged on as an administrator, you can change the status of EWF by right-clicking the icon and selecting the desired EWF state.
NOTE: Because the ewfmgr.exe utility and the EWF status service execute separate code, status
changes by ewfmgr.exe are not automatically reflected by the EWF status icon.
If you use the command line to modify the EWF, 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 EWF Control Panel utility. The EWF utility always reflects the current status.

Local drives

The following sections describe the local drives on your computer.

Drive Z

Drive Z (HP RAMDisk) is a virtual drive that is created from the system's physical RAM. The RAMDisk will look and behave like a standard fixed disk drive, but it is created at system startup and destroyed at system shutdown. Therefore, HP recommends that you do not store information or data on this virtual disk drive.
The RAMDisk is volatile memory space set aside for temporary data storage.
The following items are stored on the RAMDisk:

Drive C

Browser Web page cache
Browser history
Browser cookies
Browser cache
Temporary Internet files
Print spooling
User/system temporary files
Use the RAMDisk Configuration dialog box to configure the RAMDisk size. If you change the size of the RAMDisk, you will be prompted to restart for the change to take effect. To permanently save the change, disable the write filter cache or issue the -commit command during the current boot session before restarting.
CAUTION: If the available free space on the flash drive is reduced to below 3 MB, the computer
becomes unstable.
A write filter is used by the computer for security and to prevent excessive flash write activity. Changes to the computer configuration are lost when the computer is restarted unless the write filter cache is disabled or a -commit command is issued during the current boot session. For additional information, refer to
HP Write Filters on page 3.
8 Chapter 3 Configuration

Saving files

The computer uses an embedded operating system with a fixed amount of flash memory. HP recommends that you save files that you want to retain on a server rather than on your computer. Be careful of application settings that write to the C drive, which resides in flash memory (in particular, many applications by default write cache files to the C drive on the local system). If you must write to a local drive, change the application settings to use the Z drive. To minimize writing to the C drive, update the configuration settings.

Mapping network drives

To keep the mappings after the computer is restarted, follow these steps:
1. Disable the write filter cache during the current boot session or issue the –commit command.
2. Click Reconnect at logon.
Because a user logon cannot disable the write filter cache, you can retain the mappings created by a user by logging off the user (do not shut down or restart the computer), logging back on as administrator, and then disabling the write filter.
You can also assign the remote home directory by using the Local Users and Groups utility or by other means known to administrators.

Roaming profiles

Write roaming profiles to the C drive. The profiles need to be limited in size and will not be retained when the computer is restarted.
NOTE: For roaming profiles to work and be downloaded, sufficient flash space must be available.
You might need to remove software components to free up space for roaming profiles.
