This post will cover all the steps needed to deploy Windows 10 21H2 using SCCM (aka Configuration Manager). This is the way of upgrading to Windows 10, version 21H2, also known as the Windows 10 November 2021 Update, using SCCM Task Sequence. Microsoft announced the Windows 10 21H2 General Availability on the 16th Nov, 2021 with 30 months support cycle (Enterprise and EDU versions). Home and Pro editions of the November 2021 Update will receive 18 months of support.
Devices running Windows 10, versions 2004, 20H2, and 21H1 can update quickly to Windows 10, version 21H2 using an enablement package. Let’s check the steps to install the latest Windows version on a new computer (bare metal) using sccm. The bare metal scenario occurs when you have a blank machine you need to deploy or an existing device you want to wipe and redeploy without preserving any existing data.
This bare metal scenario helps us to install a new version of Windows on a new computer. It’s a fresh installation of the OS and doesn’t include any settings or user data migration. The deployment process for the new machine scenario is as follows:
- Start the setup from boot media (CD, USB, ISO, or PXE).
- Wipe the hard disk clean and create new volume.
- Install the operating system image.
- Apply device drivers by detecting device manufacturers.
- Install applications.
- Apply Customization, Additional settings if needed.
- After taking these steps, the computer is ready for use

Download Windows 10 21H2 ISO
Find Windows 10 (business editions), Version 21H2. Select the architecture and language. Click on Download.
Mount and Extract Windows 10 ISO
Before you import the Windows 10 Operating System into SCCM, mount and extract or copy Windows 10 ISO contents to a folder. Create a shared folder, Mount the ISO using File Explorer or any other available options.
Copy the downloaded ISO to the SCCM site server, Double-click an ISO file to mount it, or Right-click an ISO file in file explorer. Select the Mount option.
You will notice that Windows 10 ISO will create a disc drive that you can use to access contents. Select all contents and copy them to a shared source folder in SCCM Server. The content-copying process might take some time, wait to complete the process.
Note – You can locate the default OS image in the Windows source folder
\Sources\install.wim. Grab a file off of this ISO and Copy it to the shared directory to make use of it.
Import Windows 10 Operating System Image
The operating system image contains the files necessary to install the operating system on the destination computer. Use the following to prepare the operating system image –
In Configuration Manager Console, Go to Software Library > Operating Systems > Operating System Images.
Right-click on Operating Systems Images and click on Add Operating System Image.
In Data Source, click Browse and specify the network shared path to the install.wim from Windows 10 Source directory where you extracted the source of an ISO file.

On the Install Windows page, specify the following settings and click Next.
- Image package: Click on Browse to select the image. Select Partition and format the target computer installing the operating system.
- Unchecked Configure task sequence for use with BitLocker – Since we don’t want to add the Bitlocker step to the task sequence,
- Product key: you can specify the Windows product key for the OS to install.
- Specify how to handle the administrator account for the new OS. Enable the account and specify the local administrator password – Windows uses the same password for the local administrator account on all computers where the task sequence deploys the OS image.
On the Configure Network page, specify the following settings. Click Next.
- Join a workgroup: Add the destination computer to a workgroup.
- Join a domain: Add the destination computer to a domain. In Domain, click Browse to specify the name of the domain. You can also specify an organizational unit (OU) in the Domain OU field.

Deploy Windows 10 21H2 Using SCCM
Use the following procedure to deploy a task sequence to the computers in a collection.
In the Task Sequence list, select the task sequence you have created, Right-click, and select Deploy.
On the General, click Browse to select your device collection where you wish to perform the deployment.
Deploy to All Unknown Computers – Computers that are not managed by Configuration Manager or a computer not imported into Configuration Manager.
Note – When you target a deployment, the Select Collection window only displays collections that include fewer than 100 clients. If you clear the setting to Hide collections with a member count greater than the site’s minimum size configuration (100), the window displays collections that include fewer than 1000 clients. Let’s check more collection size limits in deployment verification site settings.
On the Deployment Settings, select the Purpose of the deployment.
Available – Available deployments require that the user is present at the destination computer. A user must press the F12 key to continue the PXE boot process. If a user isn’t present to press F12, the computer boots into the current OS, or from the next available boot device. Required – Required deployments use PXE without any user intervention. To use a PXE-initiated OS deployment, For the Make available to the following setting, select one of the following options – Configuration Manager clients, media, and PXE Only media and PXE Only media and PXE (hidden)
Note – Use the Only media and PXE (hidden) setting for automated task sequence deployments. To have the computer automatically boot to the deployment without user interaction, select Allow unattended operating system deployment and set the SMSTSPreferredAdvertID variable as part of the media.
On the Scheduling tab, you can specify the schedule for this deployment. Click Next.
On the User Experience tab, leave the default selected options. Click Next.
On the Alerts page, leave it default. Click Next.
On the Distribution Points page, you can specify how clients interact with the DPs to retrieve content from reference packages. Click Next.
To understand the available options in the Distribution Points tab during task sequence deployment – SCCM Task Sequence Available Deployment Options in Distribution Points Tab | ConfigMgr
Review the selected settings and click Next.
The Deployment targeted successfully to the collection. Click Close to exit the wizard.
Results – Windows 10 21H2 Deployment
Different hardware models have different experiences for PXE. To boot to the network – UEFI-based devices typically use the key and BIOS-based devices use the key.
After the device successfully boots via PXE, the task sequence wizard appears. If you password-protect the media, the user has to enter the password on this welcome page. Click Next.
Select a task sequence to run: If you deploy more than one task sequence to the device, you see this page to select a task sequence. Make sure to use a name and description for your task sequence that users can understand. Complete the Task Sequence Wizard by selecting deployed task sequence.
Click Next. The task sequence begins when the policy for the task sequence is downloaded, and the content location is verified.
Once you complete the Wizard, the deployment of the new operating system begins. When the task sequence runs, it displays the Installation progress window. Check more How to Improve SCCM Task Sequence Progress Bar End User Experience | ConfigMgr
