Question

Your company maintains a custom Windows 11 Enterprise multi-session image for Azure Virtual Desktop using Azure VM Image Builder (AIB). The image is distributed to an Azure Compute Gallery image definition. Monthly, you must patch the image and roll out the update to session hosts without disrupting users currently connected to the existing hosts. You also want to be able to roll back to a previous known-good build if the new image causes application failures. Which approach best meets these requirements?

Accepted Answer

Publish each monthly build as a new image version in the same Compute Gallery image definition, then create replacement session hosts from the latest version and phase out old hosts in drain mode.

Answer

Overwrite the existing image version in the Compute Gallery each month and rebuild all session hosts from that version.

Answer

Store each build as a managed image (not in a gallery) and reference the newest managed image directly when expanding the host pool.

Answer

Apply monthly patches directly to running session hosts with Update Management and skip rebuilding from the image entirely.
