**Update 2025-08-01:** [2507.2 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. # 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Apps/Office - The latest drivers from any of the major OEMs (Dell, HP, Lenovo, Microsoft) (yes, the latest, not some out of date enterprise CAB file from years ago) - Winget support so you can integrate any app available from Winget directly in your image - ARM64 support for the latest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) - Extract the FFUDevelopment folder from the ZIP file (recommend to C:\FFUDevelopment) - Follow the doc: C:\FFUDevelopment\Docs\BuildDeployFFU.docx ## YouTube Detailed Walkthrough The first 15 minutes of the following video includes a quick start demo to get started.
