Problem

After importing an operating system into MDT, you need to create a Task Sequence to define how that OS is deployed to target machines.

Solution

A Task Sequence is a series of steps that MDT runs to deploy Windows, install applications, apply settings, and more. You must create at least one Task Sequence to begin deploying systems.

Step-by-Step Guide

1. Open Deployment Workbench

  • Launch Deployment Workbench.
  • Expand your Deployment Share > Task Sequences.

2. Create a New Task Sequence

  • Right-click Task Sequences > New Task Sequence.
  • Enter the following details:
    • Task Sequence ID: A short, unique identifier (e.g., WIN11ENT64)
    • Name: A descriptive name (e.g., Windows 11 Enterprise x64)
    • Comments (optional): Add version or environment notes.

Click Next.

3. Choose a Task Sequence Template

  • Select Standard Client Task Sequence.
    • This is used for standard OS deployments to client devices.
    • Other templates exist for server deployment, custom tasks, and LTI capture.

Click Next.

4. Select the Operating System

  • Choose from the list of operating systems you’ve previously imported.
  • Click Next.

5. Specify Product Key

  • If you’re using KMS activation, leave this blank.
  • For MAK or Retail keys, enter the product key here.

Click Next.

6. Enter Administrator Password

  • Set a local Administrator password (optional, but recommended).
  • This applies to the built-in Administrator account on deployed machines.

Click Next, then Finish.

After Creation: Optional Configuration

Once the Task Sequence is created, you can further customize it:

A. Edit Steps

  • Right-click your new Task Sequence > Properties > Task Sequence tab.
  • You can add, remove, or reorder steps such as:
    • Install Applications
    • Format and Partition Disk
    • Apply Drivers
    • Join Domain
    • Enable BitLocker

B. Add Applications

  • Click Install Applications step.
  • Choose applications to install during deployment (can be optional or mandatory).

Best Practices

  • Use meaningful Task Sequence IDs (helps when automating or troubleshooting).
  • Keep Task Sequences modular—use conditions or roles if supporting multiple hardware types.
  • Avoid overloading a single Task Sequence with too many roles.

Notes

  • You can duplicate existing Task Sequences to save time.
  • Task Sequences are saved as XML files in the Control folder of your Deployment Share.
  • Any changes require updating the Deployment Share before they take effect in boot media.
