# 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Apps/Office - The latest drivers from any of the major OEMs (Dell, HP, Lenovo, Microsoft) (yes, the latest, not some out of date enterprise CAB file from years ago) - Winget support so you can integrate any app available from Winget directly in your image - ARM64 support for the latest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](https://github.com/rbalsleyMSFT/FFU/releases) - Extract the FFUDevelopment folder from the ZIP file (recommend to C:\FFUDevelopment) - Watch the Youtube video (updated docs for the UI coming soon) ## YouTube Detailed Walkthrough Here's a detailed overview of the new UI process.
