Breaking changes

We will soon start the deprecation process for Windows 2019. While the image is being deprecated, you may experience longer queue times during peak usage hours. Deprecation will begin on 2025-06-01 and the image will be fully unsupported by 2025-06-30.

To raise awareness of the upcoming removal, we will temporarily fail jobs using windows 2019. Builds that are scheduled to run during the brownout periods will fail. The brownouts are scheduled for the following dates and times:

• 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

Target date

Final retirement date:
2025-06-30

The motivation for the changes

We maintain the latest two stable versions of any given OS version. Windows 2025 is moved to GA on 2025-04-07 so we start deprecating the oldest image at that time.

Possible impact

Workflows using the windows-2019 image label should be updated to windows-2022 or windows-2025.
