Ensuring all your Azure Virtual Desktop images are up-to-date is crucial to maintaining the security and reliability of your environment. Regular OS and application updates not only helps you in securing your systems but also in achieving optimal performance. In this article, we will focus on applying Operating System (OS) and Application Updates to an Azure Virtual Desktop Image while preparing for exam AZ-140.
Understanding the Importance of OS and Application Updates
Before diving into the application process, it is essential to understand the significance of regularly updating your Azure Virtual Desktop images. Below are some compelling reasons:
- Security: Each update comes with security patches to address vulnerabilities that could potentially be exploited by cybercriminals.
- New Features: Updates often introduce new features and capabilities that can enhance user experience and productivity.
- Bug Fixes: Updates often include bug fixes that can improve system performance and stability.
- Compliance: Regular updates ensure that your systems meet compliance regulations, which necessitate keeping software up-to-date.
Now that we apprehend the importance of updates let’s move into the application process.
Updating Operating System (OS)
There are two common methods for updating the operating system image for Azure Virtual Desktop: manual updates and automatic updates using Azure Automation Update Management.
Manual Update
In the manual update method, you need to apply the updates manually for each image. Let’s discuss the steps:
- Start by logging into Azure Portal.
- Navigate to your Azure Virtual Desktop environment.
- Select the image you want to update.
- On the image page, click update, and select the updates to apply.
- Once selected, apply the updates. Your image will enter into maintenance mode during this period to perform the updates.
This method can be time-consuming, especially if you are managing several images.
Azure Automation Update Management
Azure Automation Update Management allows you to manage updates for your Azure Virtual Desktop images centrally. This method is more suitable for organizations with many images to manage. Here’s how you can use this approach:
- Navigate to your Azure Automation account.
- Under the “Update Management” section, select “enable” to start the setup process.
- Once enabled, you can schedule updates for your images based on your requirements.
Updating Applications
It’s equally important to keep the applications on your Azure Virtual Desktop images updated. Here are the steps:
- Log into Azure Portal and navigate to the desired Azure Virtual Desktop image.
- Launch the image and manually update each application.
- Once the updates are complete, seal the image using Sysprep or a similar utility.
- Publish the updated image.
For automating the application updates, consider using application management solutions like Chocolatey or Patch My PC, which integrate with the Azure Virtual Desktop.
Conclusion
Keeping your Azure Virtual Desktop images updated is part and parcel of properly managing your Azure environment. Both OS and application updates constitute a pivotal role in ensuring stability, security, and compliance. It’s essential to work proactively and regularly monitor patches and updates for both the OS and applications in your environment. Knowing how to manage these updates manually and automatically will be a valuable skill set when preparing for your AZ-140 exam.

Interview Questions
What is the primary purpose of applying operating system (OS) and application updates to an image in Azure Virtual Desktops?
The primary purpose of these updates is to ensure that the system and applications are secure, perform optimally, and include the latest features supported by Microsoft. Updates often include bug fixes, security updates, and feature enhancements.
How can you apply an OS update to an image in Azure Virtual Desktops?
OS updates can be applied by creating a new version of the image or patching the running VM from which the image was created. You can also automate OS updates using Azure Update Management.
How would you update an application in a shared image gallery?
You can update an application in a shared image gallery by creating a new version of the image with the updated version of the application installed. This new version can then be distributed across your host pools.
Is it recommended to automatically apply updates to an image in Azure Virtual Desktops?
Microsoft generally recommends planning and controlling when and how updates are applied rather than automatically applying them. This is to prevent potential compatibility issues with applications or system settings.
What is Azure Update Management and how is it used in the context of Azure Virtual Desktops?
Azure Update Management is a service that helps you manage updates and patches for your Azure VMs. It allows you to schedule updates, manage update compliance, and create alert rules.
In the context of updating an Azure image, what does it mean to “deprovision” a virtual machine?
Deprovisioning a VM essentially prepares it to become an image. It clears user-specific settings and data, making it ready for image capture without containing any user-specific information.
Is there any downtime when you apply updates to an image in Azure Virtual Desktops?
Yes, applying updates to an image requires a reboot of your VMs causing a brief amount of downtime. However, there are strategies like phased deployments to minimize impacts.
