With Thincast Workstation you can turn your computer into a powerful virtualization platform and share virtualized desktops with your team, while keeping the data centralized.

Thincast Workstation is currently in Beta phase, see "Versions" below.

How does Thincast Workstation relate to VirtualBox?

The virtualization system of Thincast Workstation and the graphical user interface are derived from the VirtualBox Open Source Edition.
We've added a bunch of new features and devices so there may be some differences between the usage and configuration of Thincast Workstation and VirtualBox. VirtualBox specific end-user documentation can be found here. All differences will be covered in this user manual.


We do provide different versions:

  • Stable - Official releases. Use this for production.
  • Beta - Upcoming release. Beta versions are under qualification testing, and may include significant issues.
  • Nightly - Development snapshot. Contains the latest features and improvements but isn't completely tested and may include severe issues.

The beta and nightly versions are mainly for preview and evaluation purposes. Don't use them in production!

It is the end users' responsibility to protect their systems and data when using such beta/nightly software. It is strongly recommended that end users do back up all their data prior to using beta/nightly software.

Beta and nightly software does not carry any warranties or support services.


Hosts that run Thincast Workstation must meet specific system requirements:

Host System

Supported Host Operating Systems

Thincast Workstation Beta requires a 64-bit Windows operating system with latest Service Packs installed:

  • Windows 7* / 8 / 8.1 / 10
  • Windows Server 2008 R2 / 2012 / 2012 R2 / 2016**

*: Unfortunately, there are some technical limitations on Windows 7 which decreases the performance of Thincast Workstation significantly. Therefore we highly recommend to upgrade your operating system to Windows 10!
**: Please be aware that if Microsoft Hyper-V role is installed on a Windows Server 2016, no other virtualization solution will work because Hyper-V is exclusively using the hardware virtualization layer.


The host system must have a 64-bit Intel or AMD processor with 2.2 GHz or faster core speed. Multiprocessor systems are supported.

Memory and Storage

The minimum memory required on the host system is 2 GB. 4 GB and above is recommended. Thincast Workstation needs at least 300MB of available disk space for the application. We recommend to use a SSD hard drive for storing your virtual machines.

Graphics Cards

Thincast Workstation provides full DirectX 11.2 support inside the guest operating system. This allows you to use your 3D applications with the same smooth and visual experience as running them on physical hardware.

In order to use hardware acceleration inside the VM, your graphics card must support at least DirectX 11. Please note that the GPU software drivers must support DirectX 11 Feature Level 11.0. The following list shows supported GPUs but is subject to driver support for your operating system:

  • AMD® Radeon HD 5000 series or higher
  • Nvidia® GeForce 400 series or higher
  • Intel® HD Graphics 4000 or higher

If your hardware doesn't meet these requirements, you are still able to run and use your VMs. Thincast Workstation will simply fall back to use software drawing for graphics operations. However, please note that this results in much lower performance and you might be unable to run certain applications in the guest.

To improve performance for remotely accessed VMs, Thincast Workstation is able to offload encoding of the remote display stream to the graphics card. The following graphics cards are supported:

  • AMD® Radeon HD 7000 series (with AMF support) or higher
  • Nvidia® GeForce 600/700 series (with NVENC support) or higher
  • Intel® HD Graphics 4200/Haswell processors or higher

Latest graphics card drivers on the host system are required!

Please note: Do not update your host's GPU driver or disable the GPU in your host's device manager while a guest machine is running on Thincast Workstation, otherwise the guest will crash.


Thincast Workstation requires a properly configured network to communicate with the Thincast Client. Any ethernet controller can be used that the host system supports. Overall bandwidth consumption depends on the amount of connected users, used applications, screen size and used frame rates.

The values in the following list will give you an approximate reference point for a single user running resource intensive applications such as games, 3D applications or watching a UHD movie:

Screen size Frame rate approx. bandwidth consumption
2160p (4k) 30 frames 40 Mbps
1440p (2k) 30 frames 10 Mbps
1080p 30 frames 8 Mbps
720p 30 frames 5 Mbps
480p 30 frames 2.5 Mbps
360p 30 frames 1 Mbps

  • "Virtual3D" - Hardware-accelerated graphics in the virtual machines (supporting DirectX 9 - 11.2, hardware video decoding) and Thincast HD Audio

Creating Virtual Machines

The creation of virtual machines is just the same as in VirtualBox. Please refer to the VirtualBox user manual chapter 1.7, Creating your first virtual machine.

Configuring Virtual Machines

To configure your virtual machine, click on "Settings" after you have selected a specific virtual machine.



Thincast Workstation contains an advanced shared clipboard that also works with files. By default, the shared clipboard operates in bidirectional mode. Drag'n'Drop support is not available.



GPU - Assign a GPU to a specific virtual machine

In order to use DirectX and hardware video decoding, a VM must be assigned to a specific GPU. Depending on the selected GPU, H.264 encoding can be fully or partly accelerated. If the GPU does not support H.264 encoding, software encoding will be used instead.

For more information please refer to the section Graphics cards.

Force Software H.264 encoding - If checked, the virtual machine will use software H.264 encoding.

Force V-Sync on Remote Displays - If checked, the frame rate for remote displays will be limited to 30 frames/second.

Remote Display

Remote Displays are enabled on Thincast Workstation by default. Remotely connected clients access the machine via the Remote Display.


Thincast HD Audio - If Thincast HD Audio as Audio Controller is selected, remote and local HD audio playback is enabled.


USB 3.0 device redirection through the TcXhci USB Controller is enabled by default.

Thincast Guest Additions

Our guest additions contain drivers and applications that enable DirectX, Audio and clipboard support in the guest operating system.

These guest additions have to be installed after the guest operating system has been installed.

The following x86/x64 Windows guest operating systems are supported:

  • Windows 7 / 8 / 8.1 / 10
  • Windows Server 2008 R2 / 2012 / 2012 R2 / 2012 / 2016

Virtual 3D (Direct X)

We have redesigned the graphical subsystem to provide full DirectX and hardware video decoding (Direct3D11 Video/DXVA 2) support in the virtual machines.

Thincast Workstation currently supports up to DirectX 11.2 and WDDM (Windows Display Driver Model) 1.3. DirectX 12 and WDDM 2.0 support is in the making.

USB 3.0 Device Redirection

Any USB device which is physically attached to the host can be redirected to the virtual machine. Take advantage of high-speed USB 3.0 devices in your virtualized desktops.

Unfortunately, Windows 7 and Windows Server 2008 R2 do not have built-in support for USB 3.0. Installing a third-party USB 3.0 controller driver in the guest operating system will solve this issue:

Intel® USB 3.0 eXtensible Host Controller Driver for Intel® 8/9/100 Series

Audio Playback

The Thincast HD Audio device enables guest audio playback. It also supports audio playback for remotely connected clients.
