Starting with Citrix Virtual Apps and Desktops 2511 and CWA for Windows 2511, accessibility settings propagation for Seamless applications are enabled by default.

No admin or end user configuration is needed for this feature.

For Admins

You can explicitly disable the mirroring of accessibility settings for VDAs running CVAD 2511 or later by registry.

  1. Open the Windows Registry Editor using regedit.exe.
  2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\TWI\
  3. Create a DWORD value named AccessibilityMirroring and set the value to 0 to disable.

All users accessing seamless applications hosted on that VDA will not get their client accessibility settings propagated to their seamless application.

For End users

If you do not want to mirror the accessibility settings from your endpoint to your seamless applications, you can change the default behavior by explicitly disabling accessibility mirroring on your endpoint.

  1. Open the Windows Registry Editor using regedit.exe.
  2. Navigate to HKEY_CURRENT_USER\Software\Citrix\ICA Client\Engine\Configuration\Advanced\Modules\TWI
  3. Create a DWORD value named AccessibilityMirroring and set its value to 0 to disable.

This will prevent the Windows accessibility settings set on the endpoint to propagate to all seamless applications that are launched from that endpoint.

Configuration for previous VDAs and client

For older VDAs (2503 and later) and endpoints ( CWA for Windows 2503.10 and later) Windows Accessibility setting propagation for seamless applications is disabled by default.

On the VDA, Accessibility Settings for Seamless applications can be enabled with the following registry setting:

  1. Open the Windows Registry Editor using regedit.exe.
  2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\TWI\
  3. Create a DWORD value named AccessibilityMirroring and set the value to 1 to enable.

With CWA 2503, Accessibility Setting for Seamless applications will also be disabled on the client by default and can be enabled with the following registry setting:

  1. Open the Windows Registry Editor using regedit.exe.
  2. Navigate to HKEY_CURRENT_USER\Software\Citrix\ICA Client\Engine\Configuration\Advanced\Modules\TWI
  3. Create a DWORD value named AccessibilityMirroring and set its value to 1 to enable.

Note:

For Accessibility Settings for Seamless applications to function, the registry keys must be present on both the VDA and the client.

No additional user intervention or configuration is required to enable the new accessibility settings for seamless applications.
