What’s new in Citrix Virtual Apps and Desktops 7 1903


This article describes information published with an earlier version of Citrix Virtual Apps and Desktops. For information on the current release, see the Citrix Virtual Apps and Desktops documentation.

About this release

This Citrix Virtual Apps and Desktops release includes new versions of the Windows Virtual Delivery Agents (VDAs) and new versions of several core components. You can:

  • Install or upgrade a Site

    Use the ISO for this release to install or upgrade core components and VDAs. Installing or upgrading to the latest version allows you to use all the latest features.

  • Install or upgrade VDAs in an existing Site

    If you have a deployment, and aren’t ready to upgrade your core components, you can still use several of the latest HDX features by installing (or upgrading to) a new VDA. Upgrading only the VDAs is often helpful when you want to test enhancements in a non-production environment.

    After upgrading your VDAs to this version (from version 7.9 or later), you do not need to update the machine catalog’s functional level. The 7.9 (or newer) value remains the default functional level, and is valid for this release. For more information, see VDA versions and functional levels.

Citrix Virtual Apps and Desktops 7 1903

This product release includes the following new, modified, and enhanced features.


New product names and version numbers were introduced in Citrix Virtual Apps and Desktops 7 1808. That information is retained in this article for reference. For more information, see New product names at the end of this article.

Install and upgrade: Addition of Citrix Files for Outlook component to VDA installation

Citrix Files for Outlook allows you to bypass file size restrictions and add security to your attachments or emails by sending them through Citrix Files. You can provide a secure file upload request for co-workers, customers, and partners directly in your email.

Be notified whenever someone accesses a file or sends you a file so you are always aware of what is going and can take action. You can also set different security and access levels on a file-by-file basis for greater control.

For more information, see Citrix Files for Outlook. For installation information, see Install VDAs, and Install using the command line.

Install and upgrade: Removal of Framehawk feature from VDA installers

You can no longer enable Framehawk when installing a VDA. Framehawk is now unsupported. Instead, use Thinwire with adaptive transport enabled.

Citrix policy settings for Framehawk are not valid as of this release. If you enabled Framehawk in an earlier release, ensure that the UDP ports used only by Framehawk are closed in your firewall.

Citrix Scout

  • New error message: The verification tests that run on selected machines fail if remote Windows Management Instrumentation (WMI) access is not enabled.
  • Scout now collects and saves Citrix policy information in CSV format. (In earlier releases, policy information was saved in XML.)
  • Scout now collects installation and upgrade logs.

For details, see Citrix Scout.

Call Home

Citrix Call Home now collects installation and upgrade logs. For details, see Citrix Insight Services.

Machine Creation Services (MCS) storage optimization

This release includes updates to the Citrix Provisioning storage approach using Machine Creation Services (MCS) storage optimization. For more information, see Create machine catalogs.

Citrix Director

Citrix Profile Management Duration in Profile Load

Director now includes profile processing duration in the Profile Load bar of the Logon duration chart. This is the duration Citrix Profile Management takes to process user profiles. This information helps administrators to troubleshoot high profile load durations with greater accuracy. For more information, see Profile Load.

Minor user interface change

The user interface in the Trends page contains some minor changes to the appearance – for example the hover text appears in a higher contrast in the details list. Similar changes will be rolled out over coming releases to improve the user experience and rendering speed.

New features guide

Director now has an in-product guide that gives an insight into the new features released in the current version of Director. The quick overview coupled with appropriate in-product messages helps you understand what’s new in the product. For more information, see New Features Guide.

Citrix Probe Agent TLS 1.2 compliance

Citrix Probe Agent now supports TLS (Transport Layer Security) 1.2.

Virtual Delivery Agents (VDAs) 1903

Version 1903 of the VDA for Windows Server OS and the VDA for Windows Desktop OS includes the following enhancements (in addition to the VDA installation and upgrade items listed above):

Docking and Undocking for Remote PC Access

We support docking and undocking for Remote PC Access devices. For more information, see Technical requirements and considerations.

Support for Microsoft Surface Pro and Surface Book pens with Windows Ink-based applications

We support standard pen functionality on client devices using a minimum of Microsoft Windows 10 version 1809 and a minimum of Citrix Workspace app for Windows version 1902. Support includes pointing, erasing, pen pressure, Bluetooth signals, and other features depending on the operating system firmware and pen model.

For more information, see Microsoft Surface Pro and Surface Book pens.

Addition of Transport Layer Security (TLS) to Universal Print Server

Support for Transport Layer Security (TLS) has been added to the Universal Print Server. For more information, see Transport Layer Security (TLS) on Universal Print Server.

New TLS policies for Universal Print Server have been added. For more information, see Universal Print Server policy settings.

DPI matching on Windows Server 2016 and Windows Server 2019

DPI matching allows the Windows Server 2016 or Windows Server 2019 desktop session to match the DPI of the endpoint when using Citrix Workspace app for Windows.


This setting is off by default. DPI matching is enabled whenever the DPI scaling setting is set to No. When using seamless apps, the DPI is set to 100% by default.

Support for copy and paste between sessions and clients

Using Citrix Virtual Apps and Desktops 1903 and the latest version of Citrix Workspace app for Windows, users can now copy and paste files, directories, or groups of files or directories between a session and a local client. Copy and paste functions work by using the right-click menu or keyboard shortcuts.

For more information on configuring copy and paste, see Copy and paste between session and client.


  • Cut is not supported. Requests to cut a file are treated as copy.
  • Drag and drop is not supported.
  • If a copy is initiated from one direction (client to VDA or VDA to client) initially and the other is attempted, the first operation closes without any information to the user when the second one starts – irrespective of the same or different files.

Postscript simulation and full font embedding

Users can now control image compression and Font embedding using registry keys. The new options appear in the PDF Universal Print Driver UI.

To enable or disable Enable Postscript Simulation, set the following registry key:


Name: EnablePostscriptSimulation


Value :

0 - Disable

1 - Enable

To enable or disable Full font embedding (larger file size), set the following registry key:


Name: EnableFullFontEmbedding


HDX adaptive throughput changes the way that output buffers are set by moving this mechanism from the client to the VDA, and no manual configuration is necessary. This new behavior requires both VDA version 1811 or later and Citrix Workspace app 1811 for Windows or later. It is not available in deployments with older versions of the VDA or of the client. For such older deployments, see Optimize HDX bandwidth over high latency connections for information about manual output buffer configuration. Type: REG_DWORD

Value :

0 - Disable

1 - Enable


If users have applied custom settings, they are honored. If users have changed these settings, the registry values will not be applied.


Standard fonts and Licensed fonts are checked when Full font embedding is checked. They are also controlled by the PDF optimization default policy. If there are conflicts, the registry settings are honored.

Citrix Licensing 11.15

Citrix Licensing 11.15 contains new features and fixed and known issues.

Federated Authentication Service Assertion SDK

The Federated Authentication Service (FAS) Assertion SDK includes a number of updates to the parameters of existing methods. For more information, see the Readme.txt file included in the zip download file of the Federated Authentication Service Assertion SDK. The SDK is available from the Citrix downloads page.

New product names

If you’ve been a Citrix customer or partner for a while, you’ll notice new names in our products and in this product documentation. If you are new to this Citrix product, you might see different names for a product or component.

The new product and component names stem from the expanding Citrix portfolio and cloud strategy. Articles in this product documentation use the following names.

  • Citrix Virtual Apps and Desktops: Citrix Virtual Apps and Desktops offers a virtual app and desktop solution, provided as a cloud service and as an on-premises product, giving employees the freedom to work from anywhere on any device while cutting IT costs. Deliver Windows, Linux, web, and SaaS applications or full virtual desktops from any cloud: public, on premises or hybrid. Virtual Apps and Desktops was formerly XenApp and XenDesktop.
  • Citrix Workspace app: The Citrix Workspace app incorporates existing Citrix Receiver technology as well as the other Citrix Workspace client technologies. It has been enhanced to deliver additional capabilities to provide end users with a unified, contextual experience where they can interact with all the work apps, files, and devices they need to do their best work. For more information, see this blog post.
  • Citrix SD-WAN: NetScaler SD-WAN, a crucial technology for our customers and partners transforming their branch networks and WANs with cloud technology, is now Citrix SD-WAN.
  • Citrix Secure Web Gateway: As the Citrix Networking portfolio expands, we’re proud to offer our robust Citrix Secure Web Gateway service, previously known as NetScaler Secure Web Gateway.
  • Citrix Gateway: Our robust NetScaler Unified Gateway, which allows secure, contextual access to the apps and data you need to do your best work, is now Citrix Gateway.

Implementing this transition in our products and their documentation is an ongoing process.

  • In-product content might still contain former names. For example, you might see instances of earlier names in console text, messages, and directory/file names.
  • It is possible that some items (such as commands and MSIs) might continue to retain their former names to prevent breaking existing customer scripts.
  • Related product documentation and other resources (such as videos and blog posts) that are linked from this product’s documentation might still contain former names.
  • For Citrix Hypervisor: The new name will be used on the Citrix website and in informational product materials from September 2018. You will also see the new name in the administrator consoles of some Citrix products, such as Citrix Virtual Apps and Desktops. The XenServer product release and technical documentation materials will continue to use XenServer 7.x until early 2019.

Your patience during this transition is appreciated. For more detail about our new names, see https://www.citrix.com/about/citrix-product-guide/.

New product and component version numbers

In this release, product and component version numbers are displayed in the format: 7 YYMM.c.m.b.

  • YYMM = Year and month when the product or component is planned for release. For example, a release planned for the first quarter of 2019 appears as 1903. The actual release date may vary.
  • c = Citrix Cloud release number for the month.
  • m = Maintenance version (if applicable).
  • b = Build number. This field is shown only on the About page of the product, and in the OS’s feature for removing or changing programs.

For example, Citrix Virtual Apps and Desktops 7 1809.1.0 indicates that the product released in September 2018, is associated with Citrix Cloud release 1 in that month, and is not a maintenance version. Some displays show only the version’s year and month: for example Citrix Virtual Apps and Desktops 7 1809.

In earlier releases of this product (XenApp and XenDesktop 7.18 and earlier), version numbers were displayed in the format: 7.version, where the version value incremented by one for each release. For example, the release following 7.17 was 7.18. Those earlier releases will not be updated with the new numbering format.
