What's new

Application and system update

Updated applications and system components to the latest versions (Windows 10 IoT Enterprise LTSC (21H2, Build 19044.7807), MD Kiosk 4.8.6.0639, MD Core 5.22.1) to ensure optimal performance, security, and compatibility.

Kiosk Hardened Image Upgrade from a USB Drive

Administrators can now select a USB drive as a hardened image upgrade source in the Kiosk Console, alongside the existing My OPSWAT (Internet) and Folder sources, so offline deployments can apply a new hardened image directly at the Kiosk. When a USB drive containing a valid image package is inserted, the Kiosk UI detects the package, runs validation checks, and prompts for the Exit Password if one is configured before copying the package locally and starting the upgrade.
