How does Our Windows Client work?​

Our Windows client displays content on Windows 10 and 11 OS devices. Older versions of Windows will not be compatible with our client due to compatibility and security issues.
The Windows client is compatible with any device that is operating on Windows 10, or 11.
In our Windows application, we provide and update the browser version. The current latest version of the browser is Chromium version 110.

We recommend using Windows 10, or 11 Enterprise if the device will only run Wallboard and will never be closed. On Windows 10 and 11 Enterprise, the device can run in Kiosk mode which is the most optimized way to use our application.

Content Caching On Windows​

Our client application stores all components of a piece of content on the device storage and supplies the embedded browser locally. This allows the device to load in the content without an internet connection.

The cache also reduces the network traffic significantly because media files are downloaded to the device only once, and when you display content that includes these media, the device will initially load them in from the local storage.

Windows client got flagged as a malicious software, what to do?​

Before delving into the details, it is worth emphasizing that **Wallboard's actions are never intended to be malicious **.

Here's a short list what may have triggered the monitoring tool:

  • Wallboard.exe created the scheduled task Wallboard Update: This task is solely for updating our application. We also utilize scheduled tasks for functions like Working Hours, which helps manage device sleep and wake-up times.
  • Wallboard.exe performed discovery indicative of virtualization/sandbox evasion: These "discoveries" are intended to gather device information, such as BIOS version and unique hardware IDs, for metrics purposes.
  • TabletMode-disable.exe file is an essential part of our system. It's required for the device's lock function, which disables the tablet's UI to prevent any tampering.
  • A powershell command executed by Wallboard.exe "powershell.exe" -WindowStyle hidden Remove-Item C:\Users\User\AppData\Local\Temp\WallboardUpdate.exe that is part of our update process. Its purpose is to manage the update files by downloading them and then clearing them once the update is complete or if a newer update becomes available.
caution

Additionally, please note that kflash.exe is not essential for the client app; and after version 4.0.356 it is no longer bundled with the application.

If you installed the application before version 4.0.356 the exe is still there, but you may remove it freely.
