To ensure our hosted agents in Azure Pipelines are operating in the most secure and up-to-date environments, we continuously update the supported images and phase out older ones. In October 2024, we announced support for Ubuntu-24.04. Soon, we plan to update the ubuntu-latest image to map to Ubuntu-24.04. Additionally, MacOS 15 Sequoia and Windows 2025 images will be generally available later this year. Alongside these new releases, we will deprecate older images like Ubuntu-20.04 and Windows Server 2019. Please refer to the following subsections for detailed updates on individual images.
Ubuntu
Ubuntu 24.04
General Availability of Ubuntu 24.04
The Ubuntu-24.04 Pipelines image is available since October last year. We plan to update the ubuntu-latest image to map to Ubuntu-24.04 soon. After this change all the jobs using ubuntu-latest image will run on ubuntu-24.04 instead of ubuntu-22.04. Please note that some tools are no longer available on the Ubuntu-24.04 image.
Ubuntu 20.04
Deprecation plan for Ubuntu-20.04
We are deprecating support for the Ubuntu 20.04 image in Azure Pipelines because it will reach its end of support soon. Please find the deprecation plan for the same below.
Key Dates:
• Deprecation Start Date: March 19, 2025
• Brownout period: 19th March 2025 to 28th March 2025
• Full Removal Date: April 30th, 2025
What This Means for You:
Starting from March 18, 2025, organization using the Ubuntu 20.04 image will begin to see a banner indicating the upcoming deprecation. To raise awareness about the upcoming deprecation we will temporarily fail the jobs (brownout) that are using Ubuntu 20.04 from March 19th 2025 to April 8th 2025. From April 30, 2025, the Ubuntu 20.04 image will be fully removed from our hosted agents, and any pipelines still using this image will fail to run.
Brownout schedule
19th March 2025: 21:00 – 5:00 UTC
21st March 2025: 5:00 – 13:00 UTC
25th March 2025: 13:00 – 21:00 UTC
26th March 2025: 21:00 – 5:00 UTC

1st April 2025: 13:00 – 21:00 UTC
8th April 2025: 13:00 – 21:00 UTC
Recommended Actions:
To avoid disruptions, we recommend updating your pipelines to use the Ubuntu 22.04 or 24.04 image as soon as possible. The updated Ubuntu images offer improved performance, security, and support for the latest tools and libraries.
How to find out the impacted pipelines
To find out the impacted pipelines that are using the deprecated images please run the script present here.
You can also identify pipelines that are using a deprecated (e.g. ubuntu-20.04) image, by checking the following location: https://dev.azure.com/{organization}/{project}/_settings/agentqueues
Select the ‘Azure Pipelines’ pool, then, filter on the image name, refer the following snapshot.
How to Update Your Pipelines:
1. Open your pipeline YAML file.
2. Locate the vmImage property.
3. Change the value from ubuntu-20.04 to ubuntu-22.04 (ubuntu-24.04, ubuntu-latest).
4. Save and run your pipeline to ensure it works with the new image.
Example:
pool:
vmImage: 'ubuntu-22.04'
pool:
vmImage: 'ubuntu-24.04'
pool:
vmImage: 'ubuntu-latest'
Alternate methods to use Ubuntu 20.04 in Pipeline Jobs
Customers that are still dependent on Ubuntu 20.04 even when it reaches its end of support state, have the following options to Use Ubuntu 20.04 in a pipeline:
Using a Container job allow you to specify a container image independently of the hosted pipeline image. For example:
jobs:
- job: ubuntu20
container: ubuntu:20.04
displayName: Use Ubuntu 20.04 container image
pool:
vmImage: 'ubuntu-latest'
steps:
- script: printenv
With Managed DevOps Pools, you can create an agent pool using the ubuntu-20.04 Azure Pipelines image until June 30. You can also use images from the Azure Marketplace.
Lastly, you can create a Self-hosted agent using any Operating System supported by the Pipelines Agent.
Windows
Windows Server 2025
The Windows Server 2025 image will be generally available starting June 16, 2025. Please be aware that starting from September 2, 2025, the “windows-latest” label will refer to Windows 2025 instead of windows-2022. Customers using windows-latest will receive a warning in their jobs to notify them about this change.
Windows Server 2019
As Windows Server 2025 generally available now, we will initiate the deprecation of the Windows Server 2019 as Microsoft Hosted Agent image in Azure Pipelines. We recommend that if you use Windows Server 2019 image in a Microsoft Hosted Agent, you switch to Windows Server 2022 or Windows Server 2025 image.
Important
Please note that support for Windows Server 2019 image for Microsoft hosted Agents has been extended till 31st December’2025. We will have additional brownout on 2nd December’2025 and 9th December’2025 to raise awareness about the upcoming retiral.
Who is impacted
This deprecation affects Azure DevOps Pipeline customers only if they are using Windows Server 2019 image in a Microsoft Hosted Agent. Please note that it does not impact customers using Windows 2019 in any other Agent (Self-hosted, MDP, VMSS). Refer the guidelines given below to find out the impacted pipelines in your organization. The detailed deprecation plan is outlined below.
Key Dates:
• Deprecation Start Date: 1st June 2025

• Full Removal Date: 30th June 2025 31st December 2025
What This Means for You:
In the coming weeks, organizations will begin to see a banner indicating the upcoming deprecation of Windows Server 2019 hosted image. To further raise awareness, we will temporarily fail the jobs (brownout) that are using Windows Server 2019 images from 3rd June 2025 to 24th June 2025. From 1st January 2026 onwards, the Windows Server 2019 image will be fully removed from our hosted agents, and any pipeline jobs still using this image will fail to run.

Hello Experts ,
When i open the azure devops Organization URL , i found a blank page with this message (note : many of my colleagues of the team work still having the link available).
The message :
The macOS-13 hosted image in Azure DevOps pipelines will be retired on December 4, 2025, and the Windows-2019 hosted image will retire on December 31, 2025 after a six-month extension. After these dates, any pipelines using these images will fail, so it is important to migrate to supported images in advance. For details on the brownout schedule and guidance on migration, please refer...
Any ETA concerning the public release date for the Apple silicon (ARM64) support for mac-OS image?
As it was planned for the “End of this year”, would like to know if we have more info now please
Hi Mentese macOS15 ARM64 image is now available in public preview. For information on the same, please refer here.
When does the brownout end for December 2, 2025? It is Dec. 3 and I still cannot release. According to this page:
Brownout schedule
• June 3 13:00-21:00 UTC
• June 10 13:00-21:00 UTC
• June 17 13:00-21:00 UTC
• June 24 13:00-21:00 UTC
• December 2 13:00-21:00 UTC
• December 9 13:00-21:00 UTC
The brownout should now be over.
Hi For windows we have the onebranch base containers in windows 2019 so upgrading our pipelines to 2022 or higher version is throwing us error. any idea as when this brownout would happen for onebranch. Please keep us posted.
Hi Joe we are working on the fix, you will not see these brownout failures now if you have been using the windows-latest image.
Hi Brion the brownout should have been over after the time period December 2 13:00-21:00 UTC. I checked and windows-2019 images are working fine at my end at the moment.
Thanks for pointing it out. We are actively investigating and will fix this issue at our end.
Our pipelines are still browning out, despite the window being over and the pipelines using windows-latest. This has been quite painful to deal with already, so an update would be appreciated.
@ShubhamAgarwal Thanks for checking—appreciate the quick response! For context, our pipelines were explicitly using windows-latest (not windows-2019), but they were still erroring out with the brownout message on Dec 3, even outside the UTC window. We've seen similar reports popping up (e.g., Joe McCormick's note above), so it might be worth peeking at:
Agent pool propagation delays: Hosted agents are region-distributed, so the Dec 2 flag might not have cleared globally until later (e.g., post-midnight UTC rollovers in some AZs). Checking logs from affected regions (like East US or West Europe) could confirm if it's a stale cache.
windows-latest remapping behavior:...
this comment has been deleted.
We’re still encountering brownout issues this morning. Additionally, our pipelines are configured to use “windows-latest” but are still failing during the brownout.
Hello Team,
Is there any public preview date (or just an approximate timeline) for MacOS ARM64 hosted agents?
We are currently evaluating Azure DevOps against other platforms such as GitLab for our CI/CD tooling, and the availability of MacOS ARM64 agents is critical for our mobile build pipelines. Since we are already invested in the Microsoft ecosystem, we would prefer to continue with Azure DevOps, but the lack of Apple Silicon–based hosted agents is becoming a blocker for our rollout.
If you could share even an indicative timeline, it would greatly help us plan our adoption strategy.
Hi Amal,
We expect to announce the Public Preview of MacOS ARM64 hosted agents in the coming weeks. Please lookout for the formal announcement on the same.
Hi,
In our pipeline we are currently using the following setting:
name: defaultVmImage
value: ‘Windows-latest’
However, our pipeline failed yesterday with the following error:
Windows Server 2019 has been retired. The Windows Server 2019 image has been removed as of 2025-06-30.
Do we need to update the defaultVmImage value to windows-2022 to resolve this issue or was the problem caused by a change on Microsoft’s side?
Encountered the same problem. Another user commented a fix which i havent tried yet.
Update: it worked
Hi Abhishek, please raise a service ticket if you are still seeing any failure or warning specific to windows-2019 images.
Did you get anywhere with the service ticket?
We are seeing the exact same behaviour. Having to go an update all yaml files to windows-2022 is time consuming and annoying when windows-latest should work.
Just checking… I’m using the macos 13 image self-hosted. DevOps itself is giving me a warning about my current pool, but the above says self-hosted isn’t affected?
Hi Reuben, Self-hosted agents should not receive this warning. If you notice macOS-13 retirement warnings in your pipeline, please submit a support ticket.
Any information when we can start building .NET10 applications with Azure DevOps Service? The windows-latest image doesn’t contain VS2026, so our pipeline fails now when our projects are upgraded to .NET10
@Shubham Three weeks later and still no VS2026, any update?
While it’s possible to build .NET 10 projects (with warnings), we just updated our C++ projects to build tools 14.5 and are now SOL.
We had the same question – and would like the .net 10 SDK added to the base image for windows 2025.
In case it helps you out Mikael, you can get around this by installing the SDK as a step in your build pipeline as follows:
- task: UseDotNet@2 inputs: packageType: 'sdk' version: '10.0.x'If you need a specific workload, then you can use something like this (after the prior step):
- task: DotNetCoreCLI@2 displayName: 'Install .NET MAUI Workload' inputs: command: 'custom' custom: 'workload' arguments: 'install maui'@Shubham – is there a timeline available anywhere on these kind of changes? It would be really useful to have visibility of things like this.
Hi Mikael windows-latest image will be updated to include VS2026 soon. Please look out for an update on the same here
Hi , does this apply for MMS images (https://eng.ms/docs/cloud-ai-platform/devdiv/one-engineering-system-1es/1es-docs/1es-hosted-azure-devops-pools/mms-images) too?
thanks
Is there an alternate where we don’t have to own the maintenance or update the version every time there is an update.
I see some options like ‘windows-latest’ and ‘ubuntu-latest’. Will that do the job?
You can use windows-latest or ubuntu-latest, which will always point to the latest release of the respective operating system.
