Apply updates in Azure Stack

Applies to: Azure Stack integrated systems

As an Azure Stack operator, you can apply Microsoft or OEM update packages for Azure Stack by using the Update tile in the administrator portal. You must download the update package, import the package files to Azure Stack, and then install the update package.

Download the update package

When a Microsoft or OEM update package for Azure Stack is available, download the package to a location that's reachable from Azure Stack, and review the package contents. An update package typically consists of the following files:

  • A self-extracting PackageName.exe file. This file contains the payload for the update, for example the latest cumulative update for Windows Server.
  • Corresponding PackageName.bin files. These files provide compression for the payload that's associated with the PackageName.exe file.
  • A Metadata.xml file. This file contains essential information about the update, for example the publisher, name, prerequisite, size, and support path URL.

Import and install updates

The following procedure shows how to import and install update packages in the administrator portal.


We strongly recommend that you notify users of any maintenance operations, and that you schedule normal maintenance windows during non-business hours as much as possible. Maintenance operations may affect both user workloads and portal operations.

  1. In the administrator portal, select All services. Then, under the DATA + STORAGE category, select Storage accounts. (Or, in the filter box, start typing storage accounts, and select it.)

  3. In the storage account details, under Services, select Blobs.

  8. Repeat steps 6 and 7 for the PackageName.bin and Metadata.xml files. Do not import the Supplemental Notice.txt file if included.

  9. When done, you can review the notifications (bell icon in the top-right corner of the portal). The notifications should indicate that the upload has completed.
  10. Navigate back to the Update tile on the dashboard. The tile should indicate that an update is available. Click the tile to review the newly added update package.
  11. To install the update, select the package that's marked as Ready and either right-click the package and select Update now, or click the Update now action near the top.
  12. When you click the installing update package, you can view the status in the Update run details area. From here, you can also click Download full logs to download the log files.
  13. When the update completes, the Update tile shows the updated Azure Stack version.

You can manually delete updates from the storage account after they have been installed on Azure Stack. Azure Stack periodically checks for older update packages and removes them from storage. It may take Azure Stack two weeks to remove the old packages.
