How do I automate the selection of Task Sequences in MDT?

Problem

You want to skip the Task Sequence selection screen during deployment and automatically assign a specific Task Sequence based on predefined rules or conditions.

---

Solution

You can automate Task Sequence selection using the CustomSettings.ini file by setting the TaskSequenceID property, either globally or conditionally (e.g., by model, role, or location).

---

Step-by-Step Guide

1. Determine the Task Sequence ID

• In Deployment Workbench > Task Sequences, right-click your desired Task Sequence > Properties.
• Note the Task Sequence ID (e.g., WIN11ENT64).

---

2. Edit CustomSettings.ini

• Open <DeploymentShare>\Control\CustomSettings.ini
• Add or modify the TaskSequenceID entry under the relevant section

Example – Simple Automation:

[Settings]
Priority=Default

[Default]
TaskSequenceID=WIN11ENT64

This will automatically select the WIN11ENT64 Task Sequence without user input.

---

3. Use Conditions for Advanced Logic (Optional)

You can automate Task Sequence selection based on things like hardware model, location, or user-defined roles.

Example – Based on Computer Model:

[Settings]
Priority=Model, Default

[Latitude 5430]
TaskSequenceID=WIN11ENT64

[OptiPlex 7000]
TaskSequenceID=WIN10PRO64

[Default]
TaskSequenceID=WIN11STD64

To find the model name:

• Use a command line on the target machine: cmdCopyEditwmic computersystem get model

---

4. Suppress the Selection Page (Optional)

To completely remove the Task Sequence screen from the wizard:

• Add SkipTaskSequence=YES under the relevant section:

[Default]
TaskSequenceID=WIN11ENT64
SkipTaskSequence=YES

---

Testing

• Boot into MDT and verify that the deployment skips the Task Sequence selection screen and automatically proceeds with the correct sequence.
• Check BDD.log or ZTIGather.log if automation fails.

---

Notes

• If you change the TaskSequenceID, make sure the Task Sequence exists and is spelled correctly.
• Combine with other skip options (SkipApplications, SkipUserData, etc.) for fully automated deployments.
