FFU/README.md

**Update 2026-01-13:** [2601.1 UI Preview is now available](https://github.com/rbalsleyMSFT/FFU/releases) - click the link to get the build and check out the [Youtube walk-through](https://www.youtube.com/watch?v=oozG1aVcg9M).

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

What if you could have a Windows image (Windows 10/11 or Server) 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- The latest drivers from any of the major OEMs (Dell, HP, Lenovo, Microsoft) (yes, the latest, not some out of date enterprise CAB file from years ago)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

- Download the latest [release](https://github.com/rbalsleyMSFT/FFU/releases) (2505.2 is the latest release based on the doc below; 2511.1Preview is based on the UI - updated docs are coming for the UI build). Recommend to download the UI build and watch the Youtube video and read the docx below to understand how the build script works.
- Extract the FFUDevelopment folder from the ZIP file (recommend to C:\FFUDevelopment)
- Follow the doc: C:\FFUDevelopment\Docs\BuildDeployFFU.docx (doc is for 2505.2; UI docs are in development)
