Update Core Content

Download and prepare the Windows, recovery, and driver content used by OSDeploy.

Use Update-OSDeployCore to prepare the local content library used to build OSDeploy boot images. The command downloads current Windows source files, prepares Windows and Windows Recovery Environment (WinRE) content, and updates Windows Preinstallation Environment (WinPE) drivers under $env:ProgramData\OSDeployCore.

Prepare OSDeployCore

1

Confirm the Requirements

Run the function on a workstation that meets these requirements:

• Windows 11 25H2 build 26200 or later
• PowerShell 7.6 or later installed from the MSI package
• Current OSDeploy module
• Required software
• Administrator rights
• curl.exe available in PATH
• Internet access and enough storage for Windows source files and drivers

Windows source files are large, and preparing the images can take time. Keep the elevated PowerShell session open until the command finishes.

2

Run the Update

Open an elevated PowerShell 7.6 session and run:

Update-OSDeployCore

Follow the confirmation prompts to download the Windows source files, prepare the Windows and WinRE content, and update the WinPE drivers. Existing verified content can be reused.
