Easy Guide to Deploy Windows 10 21H1 Using SCCM Task Sequence | ConfigMgr | Step-by-Step

This post will cover all the steps to deploy Windows 10 21H1 using SCCM (a.k.a Configuration Manager). Microsoft released Windows 10 21H1, also known as the May 2021 Update. This update contains all features and fixes in previous cumulative updates to Windows 10, version 20H2.

Windows 10, version 21H1, is available for users with devices running Windows 10, versions 2004 and higher, who manually seek to Check for updates via Windows Update. The recommended servicing status is Semi-Annual Channel. Learn more about the Easiest Option to Upgrade to the Latest Version of Windows 10 21H1

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 machine you want to wipe and redeploy without preserving any existing data.

This scenario installs an OS on a new computer. It’s a fresh installation of the OS and doesn’t include any settings or user data migration.

Prerequisites

Ensure you run with supported Configuration Manager version 2103 to manage Windows 10 version 21H1 deployment. The following list of the versions of Windows 10 that you can use as a client, along with different versions of Configuration Manager. Check more about the supported lists of the versions of Windows 10 for Configuration Manager.

Known Issue

You might experience problems when importing an OS to SCCM, and Its OS Version appears as 10.0.19041.928 in the Operating Systems node. The OS Major number for Windows 10 Version 21H1 is the same as Windows version 20H2. You can refer to the blog post for more details about the buildmajorminor versions of Windows 10.

Workaround: Mount the WIM on a fully patched 20hx or 21h1 host machine (without the ADK installed) and unmount the commit. Now, the offline metadata should be updated.

As mentioned, the next version of the ADK has a fix for this! For more, check the Twitter thread.
