VMware Horizon Client for Windows Release Notes
Horizon Client for Windows 4.4 | 16 March 2017
Last Updated: 16 March 2017
These release notes cover the following topics:
VMware Horizon Client for Windows makes it easy to access your Windows or Linux virtual desktop or hosted Windows desktops and applications with the best possible user experience on the
Local Area Network (LAN) or across a Wide Area Network (WAN).
- Support for Windows 10, Windows 8 and 8.1 (with Updates), and Windows 7
- Unmatched performance - The adaptive capabilities of the PCoIP display protocol and the Blast Extreme display protocol are optimized to deliver the best user experience, even over
low-bandwidth and high-latency connections. Your desktop is fast and responsive regardless of where you are.
- Simple connectivity - Horizon Client for Windows is tightly integrated with VMware Horizon 6 and Horizon 7 for simple setup and connectivity.
- Secure from any location - At your desk or away from the office, your data is delivered securely to you wherever you are. SSL/TLS encryption
is always used to protect user credentials, and enhanced certificate checking is
performed on the client. Horizon Client for Windows also supports optional RADIUS and RSA SecurID authentication. You can also install Horizon Client for Windows so that the client runs in FIPS mode.

What's New in This Release
- Support for Blast Extreme Adaptive Transport (BEAT)
With the VMware Blast display protocol, Horizon Client for Windows uses TCP networking when it connects to a server or BEAT if the agent and Blast Secure Gateway (if enabled) support BEAT connectivity. You can select network condition options to use only TCP networking or BEAT networking.
- Hide security information for enhanced security
A Horizon 7 version 7.1 administrator can configure global settings to hide security information in Horizon Client for Windows, including server URL information and the Domain drop-down menu. To authenticate when the Domain drop-down menu is hidden in Horizon Client, you must provide domain information by entering your user name in the format domain\username or username@domain in the User name text box.
- Restart a remote desktop
You can restart a remote desktop from Horizon Client for Windows. Restarting a remote desktop is the equivalent of the Windows operating system restart command.
- Proxy fail over with PAC file in Internet Explorer
Horizon Client supports proxy fail over with the Use automatic configuration script setting under Automatic configuration in Internet Options > Connections > LAN settings in Internet Explorer. To use this setting, you must create an automatic configuration script (PAC file) that returns multiple proxy servers.
- Resolution helper tooltip shows remote desktop resolution
If you drag a corner of the remote desktop window to resize it, a tooltip displays the screen resolution in the lower-right corner of the window
- Unauthenticated access to remote applications
A Horizon 7 version 7.1 administrator can create Unauthenticated Access users and entitle those users to remote applications. Unauthenticated Access users can log in to the server anonymously from Horizon Client for Windows and connect to their remote applications. For information about creating Unauthenticated Access users, see the View Administration document.
- Support for Microsoft Aero Peek
Horizon Client for Windows supports the Microsoft Aero Peek feature.
- OpenSSL 1.0.2k support
The OpenSSL library is updated to version openssl-1.0.2k.

After you install Horizon Agent 7.0.x in a Windows 7 or Windows Server 2008 R2 remote desktop, you can no longer use the Microsoft RDP display protocol to connect to the remote desktop. This problem occurs because TLSv1.0 is disabled by
default in Horizon 7 version 7.0 and later.
Workaround: Install Microsoft update 3080079: Update to add RDS support for TLS 1.1 and TLS 1.2 in Windows 7 or Windows
Server 2008 R2 in the Windows 7 or Windows Server 2008 R2 virtual machine and in any Windows 7 client machines.
When attempting to use the Real-Time Audio-Video feature on a Surface Pro 4 device, you see only a black screen. This issue occurs because the client needs to be configured to accommodate the default screen
resolution for a Surface Pro 4, which is 1920 X 1080.
Workaround: On the Windows client machine, edit the following registry keys under HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.\VMware VDM\RTAV:
- Set srcWCamFrameHeight to 1080.
- Set srcWCamFrameWidth to 1920.
The serial port redirection group policy setting Bandwidth Limit does not set a limit on the bandwidth.
Workaround: Use third-party software to limit the bandwidth.
With serial port redirection, at a high baud rate such as 115200, the performance of VMware Blast is significantly worse than PCoIP, and the connection might sometimes hang.
Workaround: Use a baud rate of 9600.
In an IPv6 environment, if you configure IP address mapping for location-based printing, users might encounter a problem accessing the printer because the client can have multiple IPv6 addresses. Anytime the client connects, it can use any one of the addresses.
Workaround: Use the location-based printing group policy setting IP Range to include the multiple addresses. However, the printing problem might still occur because the client might use a temporary address, which is not in the specified range.
If you use Horizon Client to connect to a remote desktop that has client drive redirection disabled, such as through a group policy setting, or if you connect to a remote desktop that has View Agent
6.1.0 or an earlier version
installed, no message is displayed to explain why the client drive redirection feature is not working.
On Windows 7 and Windows Server 2008 R2 desktops, if you remove a drive from being shared on the desktop, Windows Explorer continues to display the removed drive in the guest operating system.
Workaround: Close and reopen Windows Explorer.
On Windows 7 and Windows Server 2008 R2 desktops, if you open files in a shared folder on the desktop, disconnect from the desktop, and reconnect to the desktop, the left navigation pane in Windows Explorer
displays duplicate entries for the shared drive.
Workaround: Close and reopen Windows Explorer.
On Windows 7 client systems, you cannot use the Windows Media MMR feature with videos that use Dolby AC3 audio. On Windows 7 clients, Windows Media Foundation does not have the proper codec to support Dolby AC3
audio files. This issue does not occur on Windows 8.x clients.
In the Settings dialog box, pressing the Tab key has no effect.
Sometimes the virtual printing feature and location-based printing feature are not able to display the correct list of printers in the Devices and Printers window of a remote, session-based desktop. This issue can
occur with desktops provided by Windows Server 2012 RDS hosts. The printers shown within applications are correct, however.
Workaround: Log off the desktop running on the Windows Server host and reconnect to it.
Virtual printing might not work if you connect to a remote desktop using RDP, open Horizon Client on the remote desktop, launch a nested application session, and then log off and log back in to the desktop.
When you try to print from the nested application, the expected printer list might not appear. This issue only occurs after you log back in to the desktop.
Workaround: Reset the application on the remote desktop. To avoid having to set applications, use PCoIP for both ends of the session-in-session connection. That is, use PCoIP to connect to
the remote desktop and use PCoIP to connect from within the desktop to the nested application. If you are using location-based printing, you can resolve this issue by closing and reopening the application's print
If multiple Horizon clients connect to the same RDS desktop or remote application simultaneously and map to a location-based printer with the same name, the printer appears in the first client session, but not in
later client sessions. This problem also occurs for client-redirected virtual printers.
Workaround: For the client sessions in which the printer does not appear, perform a manual refresh. For a remote desktop, press F5 or refresh the Devices and Printers window. For a remote
application, close and reopen the application print dialog box. The location-based printer appears in the printer list.
If your client operating system is Windows 8.1 and you launch a Microsoft RDP session, pressing Ctrl+Alt+Insert does not send Ctrl+Alt+Del to the remote virtual desktop.
Workaround: Upgrade the operating system by installing Windows 8.1 Update.
If you use a touch-enabled screen on your client system to work in a View desktop, do not use the Enable Relative Mouse feature. This feature provides improved
mouse performance for 3D and CAD applications, but for touch-enabled screens and tablets, the mouse coordinates are not translated properly, even in 3D and CAD applications.
If you have multiple monitors with different screen resolutions and expand Horizon Client to all monitors and then select the Enable Relative Mouse feature, occasionally,
the mouse pointer might not be able to move downward beyond a certain position.
Workaround: Press Ctrl+Alt.
When a user connects to a desktop using PCoIP shortly after the desktop is powered on, autofit of the desktop window might not work. This issue happens most often if the desktop or network is under stress shortly after power-on (to start multiple applications or to map network drives, for example).
Workaround: Double-click the desktop window's title to go into window mode and double-click the title bar to go into all-monitor mode.
On Windows 10, Windows Fax and Scan hangs when using a CardScan 800 device.
When you use the Flash redirection feature to play a video on some websites, such as www.ted.com, you cannot exit full-screen mode because the Exit Full Screen button does not appear in the Flash player toolbar.
Workaround: Press Ctrl+Alt+Delete and unlock the client side to see the Horizon Client toolbar and then adjust the window size to
make the Flash player window smaller.
When you use the Flash redirection feature to play a video, if you click the Ad link at the bottom of the screen or the More Info link in the Flash player, the advertisment page does not pop up and the playback pauses.
If you enable the URL content redirection feature, registry keys and values under HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.\VMware VDM\URLRedirection remain after you uninstall Horizon Client.
If LockedGuestSize is set to 640x480 on the client machine and you launch a remote desktop in Window - Small mode, the resolution helper tooltip does not appear when you drag the window edge.
In certain circumstances, opening a local file with File > Open in a remote desktop or remote application causes the guest operating system on the Horizon Agent machine to encounter a STOP error (blue screen) or to stop responding (hang) when client drive redirection (CDR) is used. For more information, see VMware Knowledge Base (KB) article 2149417: Agent machine gets STOP error or stops responding when you open a local file shared with CDR.
