In this article, we'll dive into this revolutionary program, explain its mechanics in detail, and highlight the invaluable benefits of automation. Ready to boost your PC without breaking a sweat? Download the WinFast ZIP file now and learn how to upgrade to Windows 11 25H2 (or another version) in no time!


What is WinFast ? A Revolution for Windows 11 Installation


WinFast is a set of open-source scripts, carefully developed by the team at www.e-med-cyber.fr , that simplifies the installation or reinstallation of Windows 11 on any compatible PC. Instead of manually navigating Microsoft installer menus, fiddling with the registry to bypass hardware requirements, or risking a system crash due to human error, WinFast handles everything for you.


Key Components of the Package

The WinFast folder (provided in ready-to-use ZIP) contains:

  • install_windows_11.bat : The main launcher is ultra-simple. It checks your administrator rights, offers you the choice of language (French or English), and ensures that BitLocker is disabled before launching the main script. If necessary, it guides you step by step via an interactive tutorial.

  • Install-Win11.ps1 : The brains of the program, written in PowerShell. It orchestrates everything: system checks, ISO mounting, automatic BitLocker management, disk space monitoring, and installation launch.

  • Readme-A-lire.txt : A quick guide in French and English for immediate use.

  • A Windows 11 25H2 ISO file : Included by default for immediate installation of the latest major version (released in 2025).

  • Important tip : You don't have to use it! Simply delete this ISO from the folder and replace it with one of your choice – for example, the 24H2 version for a lighter update, or any other official Microsoft ISO. The script automatically detects the existing .iso file and uses it. No complicated configuration!


This package is designed to work on Windows 10 (version 1903 or higher) or Windows 11, in "upgrade" mode (update in place, without data loss if all goes well).


How Does WinFast Work? A Step-by-Step Guide

WinFast divides the process into 8 logical steps, all automated to minimize manual intervention. Here's a detailed overview:


  1. Preliminary Checks : The script scans your system to confirm that it is compatible (OS build ≥ 18362). If it is not, it politely alerts you and stops.

  2. ISO Search and Mount : It searches the WinFast folder for an .iso file. Once found (default 25H2, or your custom version), it mounts it virtually like a CD/DVD drive. No burning or USB required!

  3. Intelligent BitLocker Management : BitLocker (Windows' built-in encryption) can block the installation. WinFast checks its status on the C: drive, suspends protection if necessary, and even offers to delete recovery keys to avoid conflicts. An interactive tutorial is included if you need manual help.

  4. Disk Space Check : It measures the free space on C: (minimum 20 GB required) and prompts you to clean up if necessary. No surprises during installation!

  5. Circumventing Restrictions : Windows 11 imposes strict requirements (TPM 2.0, compatible CPU, Secure Boot). WinFast modifies the registry to legally ignore them, without risky third-party tools.

  6. Launching the Installation : It runs setup.exe from the ISO with the /auto upgrade option, for a smooth update. You just confirm once, and it's done!

  7. Automatic Cleaning : At the end, it unmounts the ISO and frees up the resources. Your PC is ready, without any leftovers.

  8. Intuitive User Interface : Colored messages (green for success, red for errors), clear progress, and multilingual support. Everything is explained in real time.

The whole thing takes less than 5 minutes to launch, and the installation itself varies from 30 minutes to 2 hours depending on your hardware.


The Benefits of Automation: Why WinFast is Ideal for Newbies


For computer novices—those who shy away from opening the Command Prompt or touching the registry—automation is a lifesaver. Here's why WinFast is a game changer:


  • Absolute Simplicity : Forget endless YouTube tutorials or obscure forums. Double-click the .bat file, follow 2-3 prompts, and let the magic happen. No command entry, no risk of fatal errors.

  • Enhanced Security : Built-in checks (BitLocker, disk space, compatibility) prevent common crashes. For example, without manually disabling BitLocker, your installation could fail – WinFast takes care of that for you.

  • Save Time and Stress : Instead of spending hours downloading hacker tools or struggling with Rufus to create a USB drive, everything is ready in one folder. Ideal for refreshing a slow home PC or testing a new version of Windows.

  • Total Flexibility : The interchangeable ISO (25H2 by default, but replace with 24H2 for a more stable version, or even Windows 10 if you prefer) makes the tool universal. Download the official ISO from the Microsoft website and copy it into the folder – that’s it!

  • Free and Safe : No ads, malware, or subscriptions. Based on native Windows PowerShell scripts, it's transparent and modifiable if you're curious.


In short, WinFast democratizes Windows installation: what took an expert half a day becomes a walk in the park for a novice.
