Best Guide to Deploy Windows 10 21H1 using ConfigMgr

This detailed post covers the steps to deploy Windows 10 21H1 using ConfigMgr (SCCM). We will use the ConfigMgr task sequence to deploy Windows 10 21H1 version to Windows 10 devices.

There are different ways to update your Windows 10 to version 21H1 however when you want to deploy it to larger set of computers, ConfigMgr makes your task easier. For home users the Windows 10 21H1 update can be downloaded directly via Windows update.

I am going to deploy Windows 10 21H1 using ConfigMgr 2103. If you haven’t upgraded to version 2103 yet, refer my SCCM 2103 upgrade guide.

About Windows 10 21H1 – Windows 10 May 2021 Update

Windows 10 21H1 is the latest Windows 10 release by Microsoft. It is also known as the Windows 10 May 2021 Update. This update also contains all features and fixes included in previous cumulative updates to Windows 10, version 20H2.  Windows 10, version 21H1 is available for users with devices running Windows 10, versions 1903 and higher.

Windows 10 21H1 was released on 18 May 2021 and the support ends on 13 December 2022. Windows 10 21H1 is serviced for 18 months from the release date for devices running Windows 10 Enterprise or Windows 10 Education editions.

One of the best thing about Windows 10 21H1 is it now includes Latest Cumulative Updates (LCUs) and Servicing Stack Updates (SSUs) combined into a single cumulative monthly update available via Microsoft Catalog or Windows Server Update Services.

Before you deploy Windows 10 21H1

When you got new laptops arrived you don’t want to install an older version of Windows 10 and then look to upgrade to Windows 10 21H1. Rather you can deploy the new Windows 10 21H1 using ConfigMgr task sequence. But wait there is something that you need to understand here.

You should not deploy Windows 10 21H1 without proper testing. Before you deploy Windows 10 21H1 using ConfigMgr, you must test the deployment and have a proper plan for the roll out. Be it a bare metal deployment or an in-place upgrade to 21H1, a proper planning is required. Deploy it to a limited group and test all your business applications before broad deployment.

In this post I will deploy Windows 10 21H1 using ConfigMgr to my test VM’s. If you are looking to upgrade to Windows 10 21H1, check the guide on how to upgrade to Windows 10 21H1 using SCCM.

Windows ADK requirement for Windows 10 21H1

While most of you are looking to deploy Windows 10 21H1 using ConfigMgr, you might be concerned about the Windows 10 ADK version. The good news is there is no new ADK for Windows 10, version 21H1. The ADK for Windows 10, version 2004 will also work with Windows 10, version 21H1. Read the following blog post to know about Windows 10 ADK versions.

You must always use the latest version of ADK. If you have an older version of ADK installed, you can use the step-by-step guide to update Windows ADK on SCCM Server.

Prerequisites for Windows 10 21H1 Deployment using SCCM

Before you plan to deploy Windows 10 21H1 using SCCM, here are some of the prerequisites.

  • You require Configuration Manager version 2103 and above.
  • Latest version of ADK installed.
  • Windows 10 21H1 ISO or media.
  • You must have installed and configured the PXE on the distribution point.
  • Add required drivers to the SCCM boot image and ensure they are distributed to all distribution points.

ConfigMgr Windows 10 21H1 Support

Before you deploy any new Windows 10 version you want to confirm if the new Windows 10 version is actually supported by ConfigMgr. When I say supported it means whether the ConfigMgr agent is compatible with Windows 10 version or not. So here is a helpful chart from Microsoft that shows ConfigMgr Windows 10 21H1 support.

If you want to deploy and manage Windows 10 21H1 using ConfigMgr, you must use ConfigMgr version 2103 and above. ConfigMgr 2103 agent is fully compatible with Windows 10 21H1.

Download Windows 10 21H1 ISO File

Before you deploy Windows 10 21H1 using ConfigMgr to new laptops or VM’s, let’s download the Windows 10 21H1 ISO file. To download Windows 10 21H1, you can either download it from Microsoft VLSC or Visual Studio.

Normally enterprise versions are deployed to new laptop in organizations. So I am going to download Windows 10 21H1 (business editions). Click the Download button and save the Windows 10 21H1 ISO file on SCCM server.

Add drivers for Windows 10 21H1 in Task Sequence

Along with Windows 10 21H1 deployment, deploying the drivers is also important. Otherwise you will have just the Windows 10 21H1 and no drivers installed. There are multiple ways to deploy drivers and manage driver updates. Each organization has their own way to deploy drivers and driver updates.

If I have to recommend a commonly used method to deploy drivers, that is via the task sequence again. You must first import the drivers into SCCM and then edit the task sequence and add Drivers > Apply Driver Package step. You can use the WMI to detect the laptop model and apply the right drivers.

After adding the drivers, you may add more steps to task sequence and customize it based on your requirements. Once the task sequence is ready, go to the next step.

Test Windows 10 21H1 Deployment

In the above step we deployed the Windows 10 21H1 ConfigMgr task sequence to device collection. Now you can either connect a laptop to the network or create a new VM to test Windows 10 21H1 deployment.

In my lab I am going to create a new Virtual Machine with no OS installed. I will use the same VM to install Windows 10 21H1. I have enabled ConfigMgr PXE responder service and the boot images are distributed to DP’s. Power on the VM and press F12 for network boot.

The VM downloads the boot image from the distribution point.
