AVD-Update

Update AVD Session Host Master Image in under 60 minutes

AVD-Update.ps1 assists initial configuration and monthly maintenance of Windows 10 / 11 AVD Session Host Master Images by updating the following components:

• Root Certificates - Microsoft Trusted Root Certificate Program
• Microsoft Edge for Business - Microsoft Edge Release Notes
• Google Chrome Enterprise (If installed) - Chrome Enterprise Release Notes
• Microsoft Visual C++ Redistributables - Microsoft Visual C++ Redistributable latest supported downloads
• Microsoft 365 Apps / Office 365 - Update history for Microsoft 365 Apps
• Microsoft Windows Defender - Microsoft Defender Antivirus security intelligence and product updates
• Microsoft OneDrive - OneDrive Release Notes
• Microsoft Teams v2 and the Teams Meeting Addin (If installed)
• Microsoft FSLogix (Adds local administrators to ODFC and Profile exclude groups) - FSLogix Release Notes
• Az.Accounts and Az.DesktopVirtualization PowerShell modules - AZ PowerShell Modules for AVD-Join
• Microsoft Windows Updates / Recommended updates - Installs NuGet and PSWindowsUpdate

Updating takes ~35-40 minutes and the VM reboots when complete.

All update services and tasks are disabled for each component so that they cannot run when the Image has been deployed in Production environments. It's better to run TiWorker.exe on the master image once only rather than every day on every session host.

Following the reboot, AVD-PostUpdate.ps1 must be run to complete maintenance tasks.

• Compress WinSXS - Clean up the WinSXS Folder
• Optimise .Net Framework - Native Image Generator
• Reset Windows Search
• Tidy folders and remove temporary media

Maintenance takes ~10-15 minutes

Following updates & maintenance, take a snapshot of the master VM using AVDManage.
