You have a Microsoft 365 subscription that contains an Azure Virtual Desktop deployment. You plan to install the Teams for virtualized desktop infrastructure (VDI) client on Azure Virtual Desktop…

This registry path is associated with Terminal Server AddIns for WebRTC, but it is not the specific key used by the Microsoft Teams application itself to enable its VDI optimization feature.

The HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Teams registry key is the designated location for enabling Microsoft Teams VDI optimization on a session host. By creating a DWORD value named 'IsVdiMode' with a data value of '1' under this key, the Teams client recognizes it's running in a virtualized environment, which triggers media processing offload to the local client device for an optimized audio and video experience.

HKEY_CURRENT_USER paths store user-specific settings, whereas Teams media optimization for VDI is a machine-wide configuration that should apply uniformly to all users on the session host.

This path incorrectly combines user-specific settings with Terminal Server AddIns and is not the correct registry location for configuring machine-wide Teams VDI media optimization.
