 Once a compute instance is deployed, it does not get automatically updated. Microsoft [releases](azure-machine-learning-ci-image-release-notes.md) new VM images on a monthly basis. To understand options for keeping recent with the latest version, see [vulnerability management](concept-vulnerability-management.md#compute-instance).
