What’s New in Parallels RAS 18.1

Parallels® Remote Application Server (RAS) 18.1 continues to improve user session management, simplifies access to Remote PC for end-users, adds new features for Azure Virtual Desktop integration and delivers the Parallels Client for Mac now optimized to natively run on Apple M1 and Intel chips.

Other notable features of Parallels RAS 18.1 include:

  • Granular Multifactor Authentication Configuration
  • Maintenance for Published Resources
  • Yubico - YubiKey (PIV) Support
  • Tenant Broker: Multiple Addresses for a Single Tenant

Combined User Session Management

With the new Sessions category in the Parallels RAS Console, administrators or helpdesk can efficiently manage all user sessions from the same location.

Users often require different delivery methods that are hosted on various operating systems. The Sessions category combines all user sessions and associated session details, whether they are hosted on:

  • Remote Desktop Session Hosts (RDSH)
  • Virtual Desktop Infrastructure (VDI)
  • Azure Virtual Desktop
  • Remote PCs over VDI

Furthermore, a new resources’ view displays all running published resources in the user session, along with search and filters for superior administration in small and larger deployments.

Self-Service Remote PC Access

Self-service Remote PC enables a fast and efficient method for organizations to provide employees with remote access to their desktops.

End users can enroll their Windows PC in a self-service manner to the Parallels RAS Farm. The enrolled PC is automatically added as a Remote PC and a corresponding published desktop is created and filtered to that specific user, enabling users to securely access their workstations from any device, anywhere.

The benefits of self-service Remote PC include:

  • Employees can securely access their office workstations
  • IT admins save time and resources by offloading or automating Remote PC enrollment and publishing

IT administrators may also use this functionality to install the Remote PC Agent silently and automatically enroll and publish Remote PC’s desktop to the intended user.

Note: This feature applies to standalone Remote PCs only and not to Remote PCs configured through VDI technology.

Azure Virtual Desktop Integration: New Features

We continue to improve the integration with Azure Virtual Desktop (formerly Windows Virtual Desktop) with these new features:

Override host size

Users may require resources provisioned from differently sized hosts. Ensure better resource utilization and cost optimization by allowing hosts created from a common Parallels RAS Template to be resized on admin request or as soon as they join a particular host pool.

RDP Shortpath support

Improve connection reliability and increase the bandwidth available for each user session with RDP Shortpath. This establishes direct UDP-based communication between the Client and session host and can be enabled directly from the Parallels RAS Console. VPN or public IP is required.


Streamline the management of user identities from different organizations with Security Assertion Markup Language (SAML) 2.0 single sign-on (SSO) authentication when using Microsoft Azure as the Identity Provider (IdP).

HTML5 initiated Windows Client support

Azure Virtual Desktop resources can be launched from the HTML5 Client Portal using the Parallels Client for Windows.

Added repair option for Templates

In case necessary tags on the template host are removed from the Azure portal or other mechanisms outside the Parallels RAS Console, tags are recreated when the repair option is chosen, in order to mitigate unexpected behavior.

Added Server Tools and Troubleshooting options in Template

Predefined or custom server tools and Agent troubleshooting options are available for use with templates from the Parallels RAS Console for improved management capabilities.

Parallels Client for Mac on Apple M1 and Intel Chips

Apple's latest M1 chips have been the talk of the tech world recently. The Parallels Client for Mac has been rebuilt and optimized to natively run on Apple M1 and Intel-based Mac devices, improving speed and battery life.

Parallels RAS macOS users have already experienced the Parallels Client for Mac running on M1 Mac computers through the built-in binary translation software, Rosetta 2. However, now the Parallels Client for Mac natively supports Apple M1 along with Intel-based Mac devices, bringing with it increased performance.

Dynamic Session Resolution Update

Improve the user experience for employees who access published desktops running in windowed mode when resizing the window.

Parallels RAS dynamically updates the resolution of the remote desktop in windowed mode without requiring a reconnection on changes to the window size.

Previously, the remote resolution was only set during the initial connection, however, now the resolution can also be set during connection and updated automatically when the remote desktop session window is resized.

Bidirectional Clipboard and File Transfer Control

Improve security by restricting clipboard redirection, mitigating data leakage, while at the same time still enabling users to copy or upload data to the session host as required.

Clipboard redirection, which permits copy and paste between client to session host and vice versa, may be controlled and restricted bidirectionally or unidirectionally.

Similarly, HTML5 Client file transfer can be controlled to only upload or download to or from the session host. In addition, default file upload and download location may be set and also enforced. Such configurations are available on Parallels Clients and centrally managed via Parallels RAS policies.
