Logging on
You can log on to the digital signage player either automatically or manually.
Automatic logon
The default for the WES-based digital signage player is automatic logon of the Administrator account.
The administrator can use the HP Logon Manager in the control panel to enable/disable auto logon
and change the auto logon user name, password, and domain. Only the administrator account can
change auto logon properties.
The default password for auto logon is Administrator.
Enabling automatic logon bypasses the Log On to Windows dialog box.
To log on as a different user while auto logon is enabled:
▲Press and click Start > Shut Down > Log Off.
This opens the Log On to Windows dialog box and allows you to select a different account.
4Chapter 3 Configuration
Manual logon
When automatic logon is disabled, digital signage player startup displays the Log On to Windows
dialog box. Type the logon information in the User Name and Password text boxes. Note the
following:
For a user account, the factory-default user name and password are both User.
●
For an administrator account, the factory-default user name and password are both
●
Administrator.
For security purposes, HP recommends that you change the passwords from their default
●
values. An administrator can change passwords by pressing Ctrl+Alt+Delete to open the
Windows Security dialog box, and then selecting Change Password. You cannot change the
password when logged on as a user.
Passwords are case-sensitive.
●
The administrator may create additional user accounts: right-click Computer, select Manage >
●
Local Users and Groups. However, due to local memory constraints, you should keep the
number of additional users to a minimum. For more information, see
on page 8.
Administrator logon access
To access Administrator logon regardless of the state of the digital signage player user mode:
User accounts
1.Click Start.
2.Click Log Off.
The screen for Administrator logon is displayed.
NOTE:The default password for the Administrator account is Administrator. The default user
name and password for the User account is User.
You can use the HP Logon Manager to permanently modify the default login user. Located in the
control panel, only the Administrator can access this application.

Local drives
The following sections describe the local drives located on the digital signage player.
Drive C and flash
Drive C is in the onboard flash drive (MP4) or hard disk drive (MP6). HP recommends that you do not
allow the free space on Drive C to drop below 10% of the storage device’s size.
CAUTION:If the available free space on the C drive is reduced to below 15 MB, the digital signage
player becomes unstable.
User accounts
This section describes how to create a new user account and user profile.
Creating a new user account
You must log on as Administrator to create user accounts locally or remotely. With the MP4 model,
due to local flash/disk space constraints, you should keep the number of additional users to a
minimum.
Use the User Accounts utility to create new user accounts.
To access the User Accounts utility:
Click Control Panel>User Accounts>Manage Another Account>Create a New Account.
▲
8Chapter 3 Configuration
User Accounts utility
The User Accounts utility allows the administrator to create, delete, and maintain user accounts.
To access the User Accounts utility:
Click Control Panel>User Accounts>Manage Another Account.
▲
User profiles
A new user’s profile is based on the Default User profile template, which includes policies similar to
the factory-defined Administrator account. This new account will default to membership within the
local Users group. If the Default User profile settings are changed from those set at the factory, the
changed settings are automatically applied to any newly created user profile—local or domain. Any
local accounts created or cached domain accounts logged into this device prior to changes made to
the Default User profile are unaffected by these changes—only accounts logged in or cached after
the changes are affected.
For a new user to match the characteristics of the predefined User account, the Administrator must
add the new user to the Power Users group. The user's actions are still limited while the user is in the
Power Users group. The Administrator may also want to apply specific Windows policies to the new
account to restrict certain actions or behaviors.
To create a user profile:
1.Log on as Administrator.
2.Click Start > Control Panel > User Accounts.
3.Select Manage Another Account to open the Manage Accounts window.
User accounts9
4.Select Create a New Account.
5.Type in the user name, and then select Standard User or Administrator.
6.Click Create Account and follow the on-screen instructions.
The newly created user is now a member of both the Power Users and Users groups and will have
Windows policies applied similar to that of the Administrator account. It may be desirable to apply
specific Windows policies to limit the capabilities of this new account.
To edit a user account, select User in the Manage Accounts window.
Regional and language options
The keyboard language options are preset at the factory. Should you need to make a change, the
keyboard language selection is made through the Region and Language selection in the control
panel. From this program, you can select the type of keyboard you are using as well as the layout/
Input Method Editor (IME) settings.

Write filters
Choosing the write filter
HP Windows Embedded Standard digital signage players include both the Enhanced Write Filter
(EWF) and the File-based Write Filter (FBWF) to protect the operating system.
The writer filter is disabled by default.
TIP:Choose the Enhanced Write Filter to protect an entire partition from writes, or choose the File-
based Write Filter to allow specific local applications and files to be updated dynamically.
To select the EWF or FBWF, perform the following steps:
1.Log on as an Administrator.
2.Select Start > Control Panel > HP Write Filter Configuration.
3.Select and configure the desired write filter.
4.Reboot the system for the chosen write filter selection and configuration to take effect.
Enhanced Write Filter Manager
WES includes the Enhanced Write Filter (EWF) console application command-line tool, ewfmgr.exe.
In addition to the DOS command-line tool, the WES image includes an Enhanced Write Filter GUI.
The EWF allows the operating system (OS) to boot from a disk volume residing on any read-only
media or write-protected hard drive while appearing to have read/write access to the OS. The EWF
saves all writes to another storage location called an overlay. Changes made to the overlay will not
be committed to the flash memory or hard drive unless the EWF has been disabled or the user
performs an intentional commit.
The EWF manager console application can be used 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 manager console application component in the configuration and building it into
the run-time image, you enable the use of ewfmgr.exe and the corresponding commands.
Benefits of the Enhanced Write Filter
The EWF provides a secure environment for digital signage player computing. It does this by
protecting the digital signage player from undesired writes. For the MP4 unit, the write filter also
extends the life of the digital signage player by preventing excessive flash write activity. It gives the
appearance of read-write access to the flash by employing a cache to intercept all flash writes and
returning success to the process that requested the I/O.
The intercepted flash writes stored in cache are available as long as the digital signage player
remains active, but they will be lost when the digital signage player is rebooted or shut down. To
preserve the results of writes to the registry, the contents of the cache can be transferred to the flash
on demand or manually using the Enhanced Write Filter Manager.
After the write filter has been disabled, all future writes during the current boot session are written to
the storage device, with no further caching until a reboot occurs. The write filter may also be enabled/
disabled through the command line. Always enable the writer filter after all of the permanent changes
have been successfully made.
16Chapter 5 Control panel extended selections
The EWF is a powerful tool for any digital signage player environment by preventing unauthorized
users from altering or damaging the image.
Enhanced Write Filter status service
This service creates an icon in the system tray that shows the status of EWF. The EWF Status icon
will appear as a red 'lock' when disabled, a green 'lock' when enabled, and a yellow 'lock' when the
state is set to change on the next boot.
StatusDescriptionExample
RedDisabled
GreenEnabled
YellowCommit Mode
Yellow with Red 'X'Write Filter Corrupted
NOTE:In the event of a corrupted EWF state, you may be able to correct this by issuing the
command 'rundll32 c:\windows\system32\ewfdll.dll,ConfigureEwf' from an
Administrator's command prompt (type the command exactly as shown without the quotes) and
reboot. If this is unsuccessful, you will need to re-flash the digital signage player unit with the
standard factory image provided on the web.
If you are logged-on as Administrator, you can change the status of EWF by right-clicking on the icon
and selecting the desired EWF state.
NOTE:Since EWF Manager console utility (ewfmgr.exe) and the EWF status service execute
separate code, any status changes by ewfmgr.exe will not be automatically reflected by the EWF
status icon.
To refresh the status icon after modifying EWF through ewfmgr.exe, you must right-click on the icon
(you can then click anywhere on the screen to close the context menu). However, any operations
made through the EWF status icon menu will be visible through the EWF Manager console
application. Status and changes to the Enhanced Write Filter will be synchronized between the EWF
status icon and the EWF Manager control panel applet.
Write filters17
Enhanced Write Filter GUI
The EWF GUI (part of the HP Write Filter Configuration) can be accessed through the control panel
or the Administrative Tools option only by the administrator.
To access the EWF GUI, perform the following steps:
1.Log on as an administrator.
2.Select Start > Control Panel > HP Write Filter Configuration >.
3.Click the EWF Manager icon.
4.Use the EWF GUI to select the Write Filter options.
EWF GUI Buttons
The current version of the EWF GUI includes the following buttons:
ButtonDescription
Overlay
Configuration
Clear Boot
Command
Commit Data to
Volume
NOTE:When using the Commit boot command, all the temporary contents will be permanently
written to the flash memory or hard disk. In addition, all content accessed (and changes made) after
running Commit, but before rebooting the system, will be written as well. This includes changes made
during any number of login/logout sessions before the next reboot.
This button simply brings to view 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.
This button is the same as executing ewfmgr.exe c: -NoCmd from the DOS prompt.
This button is the same as executing ewfmgr.exe c: -Commit from the DOS prompt.
18Chapter 5 Control panel extended selections
DOS command-line tool boot commands
The following table lists the EWF boot commands that are supported.
Boot CommandDescription
AllDisplays information about all protected volumes and performs a command, such as Disable, Enable,
and Commit, on each volume if specified.
CommitCommits all current level data in the overlay to the protected volume and resets the current overlay
level to 1 upon shutdown.
DisableAllows user to write to the image after the next reboot.
EnablePrevents the user from writing to the image after the next reboot.
Commitanddisable Combination of the Commit and Disable commands. This command will commit data in the overlay
upon shutdown. Additionally, EWF will be disabled after the system reboots.
NOTE:When using the Commit boot command, all the temporary contents will be permanently
written to the flash memory or hard disk. In addition, all content accessed (and changes made) after
running Commit, but before rebooting the system, will be written as well. This includes changes made
during any number of login/logout sessions before the next reboot.
Using boot commands
To use the EWF manager boot commands, type the following syntax in a command prompt:
EWFMGR <drive-letter> —[boot command].
NOTE:Because the EWF manager commands are executed on the next boot, you must reboot the
system for the command to take effect.
File-Based Write Filter Manager
WES includes the File-Based Write Filter (FBWF) console application command-line tool,
fbwfmgr.exe. In addition to the DOS command-line tool, the WES image includes a write filter GUI.
Benefits of the File-Based Write Filter
The FBWF provides a secure environment for digital signage player computing. It does this by
protecting the digital signage player from undesired writes. For the MP4 model, the write filter also
extends the life of the digital signage player by preventing excessive flash write activity. It maintains
the appearance of read and write access to write-sensitive or read-only storage to the operating
system, making read and write access transparent to applications. File and/or folder exclusions can
be configured to allow certain changes to persist, while preventing others from writing to disk.
Write filters19
File-Based Write Filter Status Service
This service creates an icon in the system tray that shows the status of FBWF. The FBWF status icon
will appear as a red 'lock' when disabled and a green 'lock' when enabled.
