Tiny11 Builder is a free, open-source tool that lets you create lightweight, customized Windows 11 installation images by removing unnecessary applications, services, and system components. Instead of downloading a pre-modified version of Windows, you can use an official Microsoft Windows 11 ISO to build a streamlined installation tailored to your needs.

Developed by NTDEV, the project uses PowerShell scripts and Microsoft's Deployment Image Servicing and Management (DISM) tools to modify Windows installation images. The resulting ISO can be used to install a less cluttered version of Windows 11, potentially reducing storage requirements and background resource usage.

Tiny11 vs. Tiny11 Core

Tiny11 Builder offers two approaches to slimming down Windows 11, depending on how much functionality you want to retain.

Tiny11 removes many preinstalled applications and optional components while preserving essential Windows functionality, including Windows Update, Microsoft Defender, and the Windows Recovery Environment. It is designed for users who want a cleaner Windows 11 installation without sacrificing the ability to receive updates, install additional features, or maintain their system.

Tiny11 Core takes a more aggressive approach, removing additional system components to produce an even smaller Windows installation. However, these reductions come with significant limitations: Windows Update, Microsoft Defender, and Windows Recovery are removed or disabled, and the component store is heavily reduced. As a result, Tiny11 Core cannot be maintained or updated like a regular Windows installation.

Tiny11 Core is primarily intended for testing, development, and disposable virtual machines rather than everyday computing.

Key Features

  • Build from official Windows ISOs: Create modified Windows 11 installation media using Microsoft's original installation files.
  • Remove unnecessary applications: Strip out preinstalled apps such as Clipchamp, News, Weather, Xbox components, and other bundled software.
  • Reduce system footprint: Produce smaller Windows installations that use less storage and may consume fewer background resources.
  • Choose between two configurations: Build a standard Tiny11 image for everyday use or Tiny11 Core for minimal testing environments.
  • Preserve essential functionality: Standard Tiny11 retains Windows Update, Microsoft Defender, and recovery tools.
  • Open-source and transparent: PowerShell scripts are publicly available, allowing users to inspect how Windows installation images are modified.

Requirements and Limitations

  • Tiny11 Builder requires a Windows environment with administrative privileges, PowerShell, and a compatible Windows 11 ISO. The scripts use DISM to mount and modify installation images before generating a new ISO.
  • Although Tiny11 can reduce Windows 11's storage footprint and remove unwanted applications, it does not guarantee better performance on every computer. Removing system components may also affect compatibility with certain applications, Windows features, or future updates.
  • Tiny11 Builder is an independent community project and is not affiliated with or supported by Microsoft. A valid Windows license is still required, and users should test customized installations before deploying them on their primary computers.

How to Use Tiny11 Builder

  • Download Tiny11 Builder and extract the files to a folder on your PC.
  • Download an official Windows 11 ISO from here.
  • Launch Tiny11 Builder with administrator privileges.
  • Select your Windows 11 ISO and choose a build mode:
    • Tiny11: Removes unnecessary apps while retaining Windows Update, Defender, and recovery features.
    • Tiny11 Core: Creates a smaller installation for testing and virtual machines, sacrificing updates and recovery functionality.
    • Custom: Lets you choose which apps and components to remove.
  • Start the build process and wait for Tiny11 Builder to generate your customized Windows 11 ISO.
  • Use the resulting ISO to create bootable installation media or install Windows 11 in a virtual machine.

Tiny11coremaker

  • All from regular tiny11maker plus the following:
  • Windows Component Store (WinSxS)
  • Windows Defender (only disabled, can be enabled back if needed)
  • Windows Update (wouldn't work without WinSxS, enabling it would put the system in a state of failure)
  • WinRE

Keep in mind that you cannot add back features in tiny11 core!
You will be asked during image creation if you want to enable .net 3.5 support!

What's New

  • Fixed the incorrect rejection of Windows 11 26H2 (build 26300) by 26100 image tools. Compatibility now follows known shared servicing bases, and tool selection checks the servicing providers rather than only the launcher. Windows 10 hosts remain supported with compatible deployment tools.
  • Replace the previous application folder with the extracted 0.1.1 ZIP. Windows images and saved build files are not changed by this app update.
  • Build a smaller Windows 11 ISO with the WinUI app. Choose Tiny11, Tiny11 Core or your own Custom removals, with Turbo mode and saved progress for interrupted builds.
  • Download the x64 ZIP for Intel/AMD PCs or ARM64 for Windows on ARM. Extract the whole ZIP and open Tiny11Builder.exe. Administrator approval is required. Checksums are included.
  • Core removes update and recovery support and disables Defender. Custom removals can break Windows. Test your ISO in a VM first.
