The desktop

This section provides a general overview of WES 7 user and administrator desktop features and functions.

User desktop

The desktop that opens when you are logged on as a user is a standard WES 7 desktop. To access applications, go to the Start menu.
For information about the functionality of the standard WES desktop and Start menu items, refer to the applicable Microsoft documentation:
2 Chapter 2 Introduction
http://msdn.microsoft.com/en-us/embedded/bb981920.aspx
NOTE: The control panel, available by clicking Start > Control Panel, provides access to a limited
set of resources for changing user preferences. You must log on as Administrator to access the extended set of control panel options and utilities.
Right-clicking the mouse when the pointer is on a user’s desktop background does not open a pop-up menu in the default windows policies configuration.

Administrator desktop

The desktop that opens when you are logged on as an administrator is a standard Windows desktop.
NOTE: Right-clicking the mouse when the pointer is on the administrator’s desktop background
opens a pop-up menu.
The desktop 3

3 Configuration

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.
4 Chapter 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.
Logging on 5

Logging off, restarting, and shutting down the digital signage player

To restart, shut down, or log off from the digital signage player:
1. Click Start > Shut Down.
2. From the Shut Down dialog box, select the desired action, and then click OK.
NOTE: You may also log off or shut down using the Windows Security dialog box. Press Ctrl+Alt
+Delete to open the dialog box.
If automatic logon is enabled, when you log off (without shutting down), the digital signage player immediately logs on the predefined User account set up in HP Logon Manager. For instructions for logging on as a different user, see
The following utilities are affected by restarting or shutting down the digital signage player:

Logging off, restarting, and shutting down the digital signage player 7

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.
8 Chapter 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 accounts 9
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.
16 Chapter 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.
Status Description Example
Red Disabled
Green Enabled
Yellow Commit 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 filters 17
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:
Button Description
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.
18 Chapter 5 Control panel extended selections
DOS command-line tool boot commands
The following table lists the EWF boot commands that are supported.
Boot Command Description
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
level to 1 upon shutdown.
Disable Allows user to write to the image after the next reboot.
Enable Prevents 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 filters 19
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.
Status Description Example
Red Disabled
Green Enabled
Yellow Commit Mode
Yellow with Red 'X' Write Filter Corrupted
If you are logged on as Administrator, you can change the status of FBWF by right-clicking on the icon and selecting the desired FBWF status.
