Deploy a task sequence
Applies to: Configuration Manager (current branch)
After you create a task sequence, and distribute the referenced content, deploy it to a device collection. This action allows the task sequence to run on a device. A deployed task sequence can run automatically, or when installed by a user of the device.
You can manage the behavior for high-risk task sequence deployments. A high-risk deployment is a deployment that is automatically installed and has the potential to cause unwanted results. For example, a task sequence that has a purpose of Required that deploys an OS is considered a high-risk deployment. For more information, see Settings to manage high-risk deployments.
Use the following procedure to deploy a task sequence to the computers in a collection.
The status messages for the task sequence deployment are displayed in the message window on a primary site, but they aren't displayed on a central administration site.
In the Configuration Manager console, go to the Software Library workspace, expand Operating Systems, and then select the Task Sequences node.
In the Task Sequence list, select the task sequence that you want to deploy.
On the Home tab of the ribbon, in the Deployment group, select Deploy.
If Deploy isn't available, the task sequence has a reference that's not valid. Correct the reference and then try to deploy the task sequence again.
On the General page, specify the following information.
Task sequence: Specify the task sequence to deploy. By default, this box displays the selected task sequence.
Collection: Select the collection that contains the computers to run the task sequence.
Don't deploy a task sequence that installs an OS to inappropriate collections, such as a collection of all your data center servers. Be sure that the selected collection contains only those computers that you want to run the task sequence.
For more information about high-risk deployments, see High-risk deployments.
Use default distribution point groups associated to this collection: Store the task sequence content on the collection's default distribution point group. If you haven't associated the selected collection with a distribution point group, this option is grayed out.
Automatically distribute content for dependencies: If any referenced content has dependencies, then the site also sends dependent content to distribution points.
Pre-download content for this task sequence: For more information, see Configure pre-cache content.
Select Deployment Template: Save and specify a deployment template for a task sequence.
Some items aren't saved in the template. Make sure you apply the following items when you run the deployment wizard:
- Software Installation
- Pre-download content
Comments (optional): Specify additional information that describes this deployment of the task sequence.
On the Deployment Settings page, specify the following information:
Purpose: From the drop-down list, choose one of the following options:
Available: The user sees the task sequence in Software Center and can install it on demand.
Required: Configuration Manager automatically runs the task sequence according to the configured schedule. If the task sequence isn't hidden, a user can still track its deployment status. They can also use Software Center to install the task sequence before the deadline.
If multiple users are signed into the device, package and task sequence deployments may not appear in Software Center.
Make available to the following: Specify whether the task sequence is available to one of the following types:
- Only Configuration Manager clients
- Configuration Manager clients, media, and PXE
- Only media and PXE
- Only media and PXE (hidden)
Use the Only media and PXE (hidden) setting for automated task sequence deployments. To have the computer automatically boot to the deployment with no user interaction, select Allow unattended operating system deployment and set the SMSTSPreferredAdvertID variable as part of the media. For more information about task sequence variables, see Task sequence variables.
Send wake-up packets: If the deployment is Required and you select this option, the site sends a wake-up packet to computers before the client runs the deployment. This packet wakes the computer from sleep at the installation deadline time. Before using this option, computers and networks must be configured for Wake On LAN. For more information, see Plan how to wake up clients.
Allow clients on a metered Internet connection to download content after the installation deadline, which might incur additional costs: This option is only available for Required deployments. When you have a custom task sequence that installs an application but doesn't deploy an OS, you can specify whether to allow clients to download content after an installation deadline when they use metered internet connections. Internet providers sometimes charge by the amount of data that you use when you're on a metered internet connection.
While using a metered internet connection might work for task sequences that don't deploy an OS, it's not supported.
On the Scheduling page, specify the following information:
When a Windows PE client starts from PXE or boot media, the client doesn't evaluate deployment schedules. These schedules include start, expire, and deadline times. Only configure schedules in deployments to clients that start from the full Windows OS. Consider using other methods, such as maintenance windows, to control active task sequences deployed to clients that start from Windows PE.
Schedule when this deployment will become available: Specify the date and time when the task sequence is available to run on the destination computer. When you select the UTC option, the task sequence is available for multiple computers at the same time. Otherwise the deployment is available at different times, according to the local time on each computer.
If the start time is earlier than the required time, the client downloads the task sequence content at the start time.
Schedule when this deployment will expire: Specify the date and time when the task sequence expires on the destination computer. When you select the UTC option, the task sequence expires on multiple destination computers at the same time. Otherwise the deployment expires at different times, according to the local time on each computer.
Assignment schedule: For a Required deployment, specify when the client runs the task sequence. You can add multiple schedules. The assignment schedule can have one of the following configurations:
- A specific date and time
- Monthly, weekly, or custom recurrence pattern
- As soon as possible
- Log on or log off events
If you schedule a start time for a required deployment that's earlier than the date and time when the task sequence is available, the Configuration Manager client downloads the content at the assigned start time. This behavior occurs even though you scheduled the task sequence to be available at a later time.
Rerun behavior: Specify when the task sequence reruns. Select one of the following options:
Never rerun deployed program: If the client has previously run the task sequence, it doesn't rerun. The task sequence doesn't rerun even if it originally failed or the task sequence files have changed.
Always rerun program: The task sequence always reruns on the client when the deployment is scheduled. It reruns even if the task sequence has already run successfully. This setting is useful when you use recurring deployments in which the task sequence is routinely updated.
This option is selected by default. However, it has no effect until you assign a required deployment. A user can always rerun available deployments.
Rerun if failed previous attempt: The task sequence reruns when the deployment is scheduled, only if it previously failed to run. This setting is useful for a required deployment. If the last attempt to run was unsuccessful, it automatically tries to rerun according to the assignment schedule.
Rerun if succeeded on previous attempt: The task sequence reruns only if it previously ran successfully on the client. This setting is useful when you use recurring deployments in which the task sequence is routinely updated, and each update requires that the previous update is installed successfully.
A user can rerun an available task sequence deployment. Before you deploy an available task sequence in a production environment, first test what happens if a user reruns the task sequence multiple times.
On the User Experience page, specify the following information:
Allow user to run the program independently of assignments: Specify whether a user can run a required deployment outside of the assignment schedule. This option is always enabled for available deployments.
Show Task Sequence progress: Specify whether the Configuration Manager client displays the progress of the task sequence.
Software installation: Specify whether the user is allowed to install software outside a configured maintenance window after the scheduled time.
System restart (if required to complete the installation): Specify whether the user is allowed to restart the computer after a software installation outside a configured maintenance window after the assignment time.
Write filter handling for Windows Embedded devices: This setting controls the installation behavior on Windows Embedded devices that are enabled with a write filter. Choose the option to commit changes at the installation deadline or during a maintenance window. When you select this option, a restart is required and the changes persist on the device. Otherwise, the application is installed to the temporary overlay, and committed later. When you deploy a task sequence to a Windows Embedded device, make sure the device is a member of a collection that has a configured maintenance window.
Allow task sequence to run for client on the Internet: Specify whether the task sequence is allowed to run on an internet-based client. Operations that require a boot media, such as the installation of an OS, aren't supported with this setting. Use this option only for generic software installations or script-based task sequences that perform operations in the standard OS.
- This setting is supported for deployments of a Windows 10 in-place upgrade task sequence to internet-based clients through the cloud management gateway. For more information, see Deploy Windows 10 in-place upgrade via CMG.
On the Alerts page, specify the alert settings that you want for this task sequence deployment.
On the Distribution Points page, specify the following information:
Deployment options: Specify one of the following options:
When you use multicast to deploy an OS, download the content to the computers either as needed or before the task sequence runs.
Download content locally when needed by the running task sequence: Specify that clients download content from the distribution point as it's needed by the task sequence. The client starts the task sequence. When a step in the task sequence requires content, it's downloaded before the step runs.
Download all content locally before starting task sequence: Specify that clients download all the content from the distribution point before the task sequence runs. If you make the task sequence available to PXE and boot media deployments on the Deployment Settings page, this option isn't shown.
Access content directly from a distribution point when needed by the running task sequence: Specify that clients run the content from the distribution point. This option is only available when you enable all packages associated with the task sequence to use a package share on the distribution point. To enable content to use a package share, see the Data Access tab in the Properties for each package.
For greatest security, select the options to Download content locally when needed by the running task sequence or Download all content locally before starting task sequence. When you select either of these options, Configuration Manager hashes the package, so that it can ensure package integrity. When you select the option to Access content directly from a distribution point when needed by the running task sequence, Configuration Manager doesn't verify the package hash prior to running the specified program. Because the site can't ensure package integrity, it's possible for users with administrative rights to alter or tamper with package contents.
When no local distribution point is available, use a remote distribution point: Specify whether clients can use distribution points from a neighbor boundary group to download the content that's required by the task sequence.
Allow clients to use distribution points from the default site boundary group: Specify if clients should download content from a distribution point in the site default boundary group, when it isn't available from a distribution point in the current or neighbor boundary groups.
Starting in version 1810, when a device runs a task sequence and needs to acquire content, it uses boundary group behaviors similar to the Configuration Manager client. For more information, see Task sequence support for boundary groups.
To save these settings to use again, on the Summary tab select Save As Template. Supply a name for the template and select the settings to save.
Complete the wizard.
Deploy Windows 10 in-place upgrade via CMG
The Windows 10 in-place upgrade task sequence supports deployment to internet-based clients managed through the cloud management gateway (CMG). This ability allows remote users to more easily upgrade to Windows 10 without needing to connect to the intranet.
Make sure all of the content referenced by the in-place upgrade task sequence is distributed to a content-enabled CMG. (Enable the CMG setting: Allow CMG to function as a cloud distribution point and serve content from Azure storage.) You can also use a cloud distribution point. Otherwise devices can't run the task sequence.
When you deploy an upgrade task sequence, use the following settings:
Allow task sequence to run for client on the Internet, on the User Experience tab of the deployment.
Choose one of the following options on the Distribution Points tab of the deployment:
Download content locally when needed by the running task sequence. Starting in version 1910, the task sequence engine can download packages on-demand from a content-enabled CMG or a cloud distribution point. This change provides additional flexibility with your Windows 10 in-place upgrade deployments to internet-based devices.
Download all content locally before starting task sequence. In Configuration Manager version 1906 and earlier, other options such as Download content locally when needed by the running task sequence don't work in this scenario. The task sequence engine can't download content from a cloud source. The Configuration Manager client must download the content from the cloud source before starting the task sequence. You can still use this option in version 1910 if needed to meet your requirements.
(Optional) Pre-download content for this task sequence, on the General tab of the deployment. For more information, see Configure pre-cache content.
Start the task sequence from Software Center. This scenario doesn't support Windows PE, PXE, or task sequence media.
When you deploy a high-risk deployment, such as an OS, the Select Collection window displays only the custom collections that meet the deployment verification settings that are configured in the site's properties. High-risk deployments are always limited to custom collections, collections that you create, and the built-in Unknown Computers collection. When you create a high-risk deployment, you can't select a built-in collection such as All Systems. To see all custom collections that contain fewer clients than the configured maximum size, disable the option to Hide collections with a member count greater than the site's minimum size configuration. For more information, see Settings to manage high-risk deployments.
The deployment verification settings are based on the current membership of the collection. After you deploy the task sequence, Configuration Manager doesn't reevaluate the collection membership for the high-risk deployment settings.
For example, let's say you set Default size to 100 and the Maximum size to 1000. When you create a high risk deployment, the Select Collection window only displays collections that contain fewer than 100 clients. If you clear the Hide collections with a member count greater than the site's minimum size configuration setting, the window displays collections that contain fewer than 1000 clients.
When you select a collection that contains a site role, the following behavior applies:
If the collection contains a site system server, and you configured the deployment verification settings to block collections with site system servers, then an error occurs. You can't continue creating the deployment.
If one of the following criteria applies, then the Deploy Software Wizard displays a high-risk warning. To continue, you need to agree to create a high-risk deployment. The site generates an audit status message.
If the collection contains a site system server, and you configured the deployment verification settings to warn on collections with site system servers
If the collection exceeds the default size value
If the collection contains a server
