1 Getting started
This guide is for administrators of HP thin clients based on the Windows® 10 IoT Enterprise operating system.
It is assumed you are using an operating system image provided by HP and that you will log on to Windows as
an administrator when making system configurations or using administrative apps as discussed in this guide.
NOTE: Information at websites listed in this table might be available in English only.

NOTE: The name of the administrator account depends on the version of the HP thin client image.
● User—Cannot make permanent changes to the system and is for end-user operation
The User account logs on automatically when Windows starts, so you must switch to the Administrator or
Admin account manually using the default password Administrator or Admin respectively.
To switch back to the User account, use the default password User.
NOTE: User account passwords are case sensitive. HP recommends changing the passwords from their
default values. For more information about user accounts, including how to change a password, see Managing
user accounts on page 8.
TIP: On a touch screen, a right-click can be performed by touching and holding the desired location.

Press the Windows key + X, and then select Control Panel from the menu.
Local drives
There are two local drives by default:
● C: (flash drive)—This is the physical drive where the operating system and apps are installed. This drive
is protected by Unified Write Filter (see Unified Write Filter on page 3).
CAUTION: The system might become unstable if the free space on the flash drive drops below 10%.
● Z: (RAM drive)—This is a virtual drive created using RAM. This drive behaves like a physical drive, but it is
created at system startup and destroyed at system shutdown. You can configure the size of this drive
with HP RAMDisk Manager (see HP RAMDisk Manager on page 12).
Unified Write Filter (UWF) is an operating system component that protects the contents of and decreases wear
on the flash drive of a thin client by redirecting and caching writes in an overlay, which is a virtual storage
space in RAM that tracks changes to a protected volume (the flash drive). The user experience in Windows is
unaffected because the operating system maintains the appearance of writing to the flash drive. When a
system restart occurs, the overlay cache is cleared, and any changes made since the last system startup are
lost permanently. If it is necessary to make permanent system configurations, an administrator can commit
(persist by writing through to the protected volume) changes stored in the overlay cache prior to a system
restart.
NOTE: The overlay cache is cleared only by a system restart, so users can log out or switch between user
accounts without losing the cached information.
UWF allows you to manage on a per-file basis, so you can immediately (without a system restart) commit files
individually or restore files to their previous state from the underlying volume by discarding the changes. You
can also exclude files from protection so that changes to them are always written directly to the flash drive.
However, you cannot commit the entire UWF overlay cache in a single command.

UWF management overview
There are three tools you can use to manage UWF: a notification icon, a Control Panel app, and a command-
line tool. Some commands can be performed using any of the tools, but other commands might be exclusive
to one or two of the tools.
Notification icon
The UWF notification icon is located in the Windows notification area. The following commands can be
executed by right-clicking the notification icon and selecting the desired option:
● Enable—Enables UWF (requires a system restart)
● Disable—Disables UWF (requires a system restart)
● Clear Command—Clears the previously-set boot command (such as Enable or Disable)
The following table describes the possible states of the UWF notification icon.
Icon Description
The memory usage of the UWF overlay cache has reached a warning level.
The memory usage of the UWF overlay cache has reached a warning level, and UWF will be disabled (requires a
system restart)
The memory usage of the UWF overlay cache has reached a critical level.
The memory usage of the UWF overlay cache has reached a critical level, and UWF will be disabled (requires a
system restart)
UWF is corrupted.
● Edit the exclusion list to add or remove files and folders (requires a system restart)
● Set the overlay cache threshold (requires a system restart)
● Set the percentage of cache usage at which warning and critical messages each display
● Set the delay for an automatic system restart that occurs when a critical state is reached
Command-line tool
The following table describes common-line options for UWF.

(repeat as necessary).
CAUTION: Changes to items in the exclusion list are always written directly to the flash drive, so keep the exclusion list to a minimum.
NOTE: Items can be removed from the exclusion list using either the HP Unified Write Filter Configuration app or the command-line
option (requires a system restart).
The following table describes the icons used for the exclusion list in the HP Unified Write Filter Configuration
app.

The item will be added to the exclusion list (requires a system restart).
The item will be removed from the exclusion list (requires a system restart).
Registry filtering
CAUTION: The UWF component by Microsoft provides registry-filtering functionality, which includes the
ability to add registry keys to a registry exclusion list and to commit individual registry keys. However,
documentation about the registry filter is limited, and due to the complexity of Windows, dependencies are
not always clear. Although the HP Unified Write Filter Configuration app provides easy access to the registry
exclusion list, HP does NOT support or recommend using the registry filtering capabilities of UWF. Usage of
this functionality is at your own risk.
IMPORTANT: Due to space constraints on the flash drive, keep the number of user accounts to a minimum.
Changing a password
To change the password for a user account:
▲ Select Start, select Settings, select Accounts, select Sign-in options, select the Change button under
the Password heading, and then follow the on-screen instructions.
NOTE: Passwords can be changed by administrators only. A user cannot change their own password.
NOTE: For information about configuring a specific user account to log on automatically at system startup,
see HP Logon Manager on page 12.
A new user account has a user profile based on a default template. A user profile contains configuration
information for a user account, such as desktop settings, network connections, and app settings. A user
profile can either be local (specific to a thin client) or roaming (server-based and accessible from multiple
different thin clients).
NOTE: Local copies of roaming profiles should be written to the flash drive (C:), which must have sufficient
free space for them to work. Roaming profiles are not retained when the system restarts.
8 Chapter 3 Configuration
Configuring the system date and time settings
The Windows Time service is set to Manual (Trigger Start). By default, this service attempts to synchronize
with the Microsoft time server (time.windows.com) every seven days. If the thin client is joined to a domain,
this service tries to sync its time with an available DC or an NTP server, if one is available.
The Date and Time app in Control Panel allows you to set the system date and time manually. To open this
app:
▲ In Control Panel, select Date and Time.
TIP: You can access this app also using the clock in the Windows notification area.
Installing apps
To install an app:
1. Disable UWF (requires a system restart).
2. Perform the installation.
NOTE: If the installation process requires a system restart, you should perform that restart before
proceeding to the next step.
IMPORTANT: Be sure to change the environmental variables back to their original values afterwards.
Citrix Receiver
Citrix® Receiver is used when Citrix Presentation Server, XenApp, or XenDesktop® is deployed with Web
Interface. Citrix Receiver enables icons to be placed on the Windows desktop for the seamless integration of
published apps.
To open Citrix Receiver:
▲ Select Start, select All apps, and then select Citrix Receiver.
4. Enter the following command on the command line to install Citrix Receiver:
CitrixReceiver.exe /includeSSON ENABLE_SSON=Yes /silent
NOTE: If a Windows server is used, a Terminal Services Client Access Licenses (TSCAL) server must also
reside somewhere on the network. A Client Access License (CAL) permits a client to use the services provided
by the Windows server. The server grants temporary licenses (on an individual device basis) that are good for
90 days. Beyond that, TSCALs must be purchased and installed on the TSCAL server. A client cannot make a
connection without a temporary or permanent license.
NOTE: Some apps might not be preinstalled on some HP thin client image versions. If an app is not
preinstalled, see Finding more resources on page 1 for information about downloading add-ons from HP.
HP Device Manager
HP Device Manager (HPDM) provides the capability for centralized, server-based administration of HP thin
clients. The client-side component is HPDM Agent.
To open HPDM Agent:
▲ In Control Panel, select HPDM Agent.
For more information, see the administrator guide for HP Device Manager.
HP Easy Shell
HP Easy Shell allows you to configure connections, websites, and apps for kiosk-style deployments of HP thin
clients based on Windows® operating systems. You can also customize the kiosk interface that is presented to
end-users and enable or disable user access to specific Control Panel settings. The configured environment
can be deployed to multiple thin clients using HP Device Manager (HPDM).
To open HP Easy Shell (the kiosk interface for end users or administrator testing):
▲ Select Start, select All apps, select HP, and then select HP Easy Shell.
To open HP Easy Shell Configuration (the configuration app for administrators):
▲ In Control Panel, select HP Easy Shell Configuration.
For more information, see the administrator guide for HP Easy Shell.
HP Logon Manager
To configure the thin client to log on to a specific user account automatically:
1. In Control Panel, select HP Logon Manager.
2. In the Windows Logon Configuration dialog box, check the Enable Autologon box, type the account
credentials and domain name, and then select OK.
TIP: To log on as a different user or as an administrator when automatic logon is enabled, simply log off the
current account to return to the Windows logon screen.
HP RAMDisk Manager
HP RAMDisk Manager allows you to configure the size of the RAM drive (Z:).
To open HP RAMDisk Manager:
▲ In Control Panel, select HP RAMDisk Manager.
HP Velocity
HP Velocity is a quality of service (QoS) system that dramatically improves the user experience for real-time,
networked apps by reducing packet loss on IP-based networks used to carry the app traffic. The HP Velocity
client-side component is preinstalled on HP thin clients and works in conjunction with a server-side
component.
For more information, see the administrator guide for HP Velocity.
