IMPORTANT: AVD customers – migrate your RX and LEAF OS firmware to 4.2.8 (or newer) by June 30, 2023

IMPORTANT information applicable only for customers using Azure Virtual Desktop (AVD) or Windows 365:


We have implemented critical client-side changes in the 4.2.8 firmware version of LEAFOS, EX500, RX420(RDP), RX440(RDP) and RX-RDP+ devices to adapt to a newly optimized Azure backend for the AVD service.

Customers using older firmware versions prior to 4.2.8 may experience stability issues when conecting to AVD sessions.  To avoid being impacted by Microsoft's upcoming change to their Azure infrastructure, you must upgrade your LEAFOS, EX500, RX420(RDP), RX440(RDP) and RX-RDP+ devices to firmware version 4.2.8 (or newer) by June 30, 2023.

The latest RX and LEAF OS firmware images can be downloaded directly from NComputing software download page:
