Concepts
To ensure optimal performance and security, it is important to regularly update your session hosts in Azure Virtual Desktop. Updates introduce new features, fix bugs, and address security vulnerabilities. In this article, we will discuss a recommended update strategy for session hosts in Azure Virtual Desktop, utilizing information from Microsoft documentation.
1. Understand the Update Process:
Before diving into the update strategy, it is essential to understand how updates are delivered to Azure Virtual Desktop. Microsoft releases updates for Azure Virtual Desktop components that include the host operating system, agent, and other related software. These updates are typically delivered through Windows Update or Azure Virtual Desktop-specific update channels.
2. Define Your Update Schedule:
Establishing a well-defined update schedule ensures that your session hosts are regularly updated without causing significant disruptions to end-users. You should consider factors such as maintenance windows, peak application usage times, and regulatory compliance requirements when determining the update schedule.
3. Validate Updates in a Test Environment:
Before deploying updates to production session hosts, it is recommended to validate them in a test environment. Create a separate Azure Virtual Desktop deployment with a few session hosts that closely mimic your production environment. Test the updates thoroughly in this environment to identify any compatibility issues or unexpected behavior.
4. Enable Update Compliance Monitoring:
To closely monitor the update status of your session hosts, enable the Update Compliance feature. This feature provides insights into the compliance status of updates installed on session hosts, helps identify missing updates, and ensures that your environment is up to date.
5. Configure Automatic Updates:
Configure automatic updates on session hosts to ensure that critical updates are installed promptly. Utilize the built-in Windows Update functionality to automatically download and install Windows updates on session hosts. This ensures that the latest security patches and bug fixes are applied regularly. Alternatively, you can leverage Azure Update Management for a centralized update management solution.
6. Leverage Azure Virtual Desktop Update Baselines:
Azure Virtual Desktop offers update baselines that define relevant updates for Azure Virtual Desktop components. You can apply these baselines to session hosts to ensure consistent updates across your deployment. These baselines are regularly updated by Microsoft to include the latest recommended updates.
7. Regularly Patch Session Host Images:
If you are using custom session host images in Azure Virtual Desktop, it is crucial to keep them patched with the latest updates. Create a regular patching process for your session host images, ensuring that the images include the latest Windows updates, agent updates, and other critical software updates. This approach allows you to deploy session hosts from up-to-date images quickly.
8. Monitor and Remediate Update Failures:
Monitor update deployments and promptly address any update failures. Azure Virtual Desktop provides logs and diagnostic information that can help identify the root cause of update failures. Leverage these logs to troubleshoot and remediate update-related issues, ensuring that session hosts are kept updated.
9. Consider a Staggered Deployment:
If you have a large number of session hosts, consider deploying updates in a staggered manner. For example, divide your session hosts into groups and schedule updates for each group at different times. This approach minimizes the impact on the entire environment simultaneously and allows you to identify any unforeseen issues early.
10. Stay Informed about Azure Virtual Desktop Updates:
Keep an eye on Microsoft’s official documentation, release notes, and Azure Virtual Desktop community forums for updates, announcements, and best practices. Stay informed about new features, improvements, and any potential issues related to updates. This knowledge will help you make informed decisions and stay ahead of any potential challenges.
In conclusion, regularly updating session hosts is paramount to ensure performance, security, and compatibility in your Azure Virtual Desktop deployment. By following this recommended update strategy, you can keep your session hosts up to date with the latest updates while minimizing disruptions and maintaining a stable environment.

For updating session hosts, I recommend using Azure Image Builder in combination with a Shared Image Gallery. It streamlines the process substantially.
Thanks for this blog post!
I found that using Azure DevOps pipelines for automated deployment can be very effective. Anyone else tried this?
What about using Azure Update Management for patching session hosts? Any thoughts?
I recommend using automatic pool resizing in Azure to dynamically adjust the number of session hosts based on demand. This ensures optimal resource utilization.
For updates, I suggest using a staging environment to test new updates before rolling them out to production session hosts.
Implementing maintenance windows for updates can help minimize disruption for users.
Always ensure to backup the current state before applying any updates. This provides a rollback option in case things go south.
