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• The latest drivers from any of the major OEMs (Dell, HP, Lenovo, Microsoft) (yes, the latest, not some out of date enterprise CAB file from years ago)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.

Getting Started

If you're new, check out the Quick Start Guide.

This will be the fastest way to create your first FFU. There's a new FFU Builder Quickstart Youtube video based on the 2602.1 UI Preview release.

Older Youtube Videos

2507.1 UI Preview Video - First UI Preview release video. This goes deeper than the quick start video, but is missing some features that have been added since 2507.1 was released.

2407.2 Video - This was the main deep-dive video on FFU Builder (before it had that name). This is a good deep dive into how the BuildFFUVM.ps1 script works, but a lot has changed since that build.
