Table 1. Horizon Client Configuration Template: General Settings
Setting Computer User Description
Allow Blast connections to use operating system proxy settings X Configures proxy server use for VMware Blast connections.

When this setting enabled, VMware Blast can connect through a proxy server.

Always hide the remote floating language (IME) bar for Hosted Apps X X Forces the floating language bar off for application sessions. When this setting is enabled, the floating language bar is never shown in a published application session, regardless of whether the local IME feature is enabled. When this setting is disabled, the floating language bar is shown only if the local IME feature is disabled. This setting is disabled by default.
Always on top X Determines whether the Horizon Client window is always the topmost window. Enabling this setting prevents the Windows taskbar from obscuring a full-screen Horizon Client window. This setting is disabled by default.
Automatic input focus in a virtual desktop window X X When this setting is enabled, Horizon Client sends input to the remote desktop automatically when a user brings the remote desktop to the front. In other words, focus is not in the frame of the window, and the user does not need to click inside the remote desktop window to move focus.
Automatically install shortcuts when configured on the Horizon server X When published application and remote desktop shortcuts are configured on a Connection Server instance, this setting specifies how and whether the shortcuts are installed on client machines when users connect to the server.

When this setting is set to Enabled, shortcuts are installed on client machines. Users are not prompted to install the shortcuts.

When this setting is set to Disabled, shortcuts are never installed on client machines. Users are not prompted to install the shortcuts.

Users are prompted to install the shortcuts by default.

Automatically synchronize the keypad, scroll and caps lock keys X When this setting is Enabled, the toggle states of the Num Lock, Scroll Lock, and Caps Lock keys are synchronized from the client device to a remote desktop. In Horizon Client, the Automatically synchronize the keypad, scroll and cap lock keys setting check box is selected and the setting is dimmed.

When this setting is Disabled, the toggle states of the Num Lock, Scroll Lock, and Caps Lock keys are not synchronized from the client device to a remote desktop. In Horizon Client, the Automatically synchronize the keypad, scroll and cap lock keys setting check box is deselected and the setting is dimmed.

When this setting is Enabled or Disabled, users cannot modify the Automatically synchronize the keypad, scroll and cap lock keys setting in Horizon Client.

When this setting is not configured, a user can enable or disable lock key synchronization for a remote desktop by configuring the Automatically synchronize the keypad, scroll and cap lock keys setting in Horizon Client. See Configure Lock Key Synchronization.

This setting is not configured by default.

Block multiple Horizon Client instances per Windows session X Prevents a user from starting multiple Horizon Client instances during a Windows session.

When this setting is set to Enabled, Horizon Client runs in single-instance mode and a user cannot start multiple Horizon Client instances in a Windows session.

When this setting is set to Disabled, a user can start multiple Horizon Client instances in a Windows session. This setting is disabled by default.

Custom error screen footer X Enables you to add custom help text to the bottom of all Horizon Client error messages. You must provide the help text in a plain text (.txt) file on the local client system. The text file can contain up to 2048 characters, including control characters. Both ANSI and Unicode encoding are supported.

When this setting is set to Enabled, you specify the full path to the file that contains the custom help text in the text box provided, for example, C:\myDocs\errorFooter.txt.

This setting is disabled by default.

Default value of the "Hide the selector after launching an item" check box X X Sets whether the Hide the selector after launching an item check box is selected by default. This setting is disabled by default.
Disable desktop disconnect messages X X Specifies whether messages that are normally shown upon remote desktop disconnection are disabled. These messages are shown by default.
Disable sharing files and folders X Specifies whether client drive redirection functionality is available in Horizon Client.

When this setting is set to Enabled, all client drive redirection functionality is disabled in Horizon Client, including the ability to open local files with published applications. In addition, the following elements are hidden in the Horizon Client user interface:

  • Sharing panel in the Settings dialog box.
  • Share Folders item in the Option menu in a remote desktop.
  • Sharing item for Horizon Client in the system tray.
  • Sharing dialog box that appears the first time you connect to a remote desktop or application after you connect to a server.

Disable time zone forwarding X Determines whether time zone synchronization between the remote desktop and the connected client is disabled.
Disable toast notifications X X Determines whether to disable toast notifications from Horizon Client.

Enable this setting if you do not want the user to see toast notifications in the corner of the screen.

Note: If you enable this setting, the user does not see a five-minute warning when the Session Timeout function is active.
Disallow passing through client information in a nested session X Specifies whether Horizon Client is prevented from passing through client information in a nested session. When enabled, if Horizon Client is running inside a remote session, it sends the actual physical client information instead of the virtual machine device information. This setting applies to the following client information: device name and domain, client type, IP address, and MAC address. This setting is disabled by default, which means passing through client information in a nested session is allowed.
Display modifier function key X X Specifies the switch modifier and function key combination that a user can press that, when grabbed and injecting input into a PCoIP or VMware Blast remote desktop session, changes the display configuration on the client machine.

When this setting is not configured (the default setting), the end user must use the mouse to ungrab the remote desktop and then press the Windows logo key + P to select a presentation display mode.

This setting does not apply to published application sessions.

Disable opening local files in hosted applications X Specifies whether Horizon Client registers local handlers for the file extensions that hosted applications support.

When this setting is set to Enabled, Horizon Client does not register any file extension handlers and does not allow the user to override the setting.

When this setting is set to Disabled, Horizon Client always registers file extension handlers. By default, file extension handlers are registered, but users can disable the feature in the Horizon Client user interface by using the Turn on the ability to open a local file with a remote application from the local file system setting on the Sharing panel in the Settings dialog box. For more information, see Share Access to Local Folders and Drives with Client Drive Redirection.

This setting is disabled by default.

Don't check monitor alignment on spanning X By default, the client desktop does not span multiple monitors if the screens do not form an exact rectangle when they are combined. Enable this setting to override the default. This setting is disabled by default.
Enable multi-media acceleration X

Determines whether multimedia redirection (MMR) is enabled on the client.

MMR does not work correctly if the Horizon Client video display hardware does not have overlay support.
