Using Full Flash Update (FFU) files to speed up Windows deployment

What if you could have a Windows image (Windows 10/11/Server/LTSC) that has:

• The latest Windows cumulative update
• The latest .NET cumulative update
• The latest Windows Defender Platform and Definition Updates
• The latest version of Microsoft Edge
• The latest version of OneDrive (Per-Machine)
• The latest version of Microsoft 365 Apps/Office
• The latest drivers from any of the major OEMs (Dell, HP, Lenovo, Microsoft) (yes, the latest, not some out of date enterprise CAB file from years ago)
• Winget support so you can integrate any app available from Winget directly in your image
• ARM64 support for the latest Copilot+ PCs
• The ability to bring your own drivers and apps if necessary
• Custom WinRE support

And the best part: it takes less than two minutes to apply the image, even with all of these updates added to the media. After setting Windows up and going through Autopilot or a provisioning package, total elapsed time ~10 minutes (depending on what Intune or your device management tool is deploying).

The Full-Flash update (FFU) process can automatically download the latest release of Windows 11, the updates mentioned above, and creates a USB drive that can be used to quickly reimage a machine.

Updates

2507.1 has been released to preview! This is a major update that brings a new user interface to preview.

Docs are coming, but will take a bit to write them. The youtube video is a must watch for a complete demo on how to use the UI and the changes made to apps (InstallAppsAndSysprep.cmd is gone) and drivers. I'll be recording a more formalized deep dive with slides that go a bit deeper into how things work, but the UI walkthrough should get most people going.

Getting Started

• Download the latest release
• Extract the FFUDevelopment folder from the ZIP file (recommend to C:\FFUDevelopment)
• Watch the Youtube video (updated docs for the UI coming soon)
