How to download Tiny11 ISO for Windows 11 25H2

To download the Tiny11 ISO for Windows 11 25H2, first download the ISO file from the official Microsoft support website.
Then, you need to use the Tiny11 Builder script to remove unwanted apps, such as Edge, OneDrive, and Xbox, and set up a local account.
This process creates a custom, debloated Windows 11 ISO ready for a clean install.
These instructions were tested in April 2026 and remain accurate.

If you want a clean installation of Windows 11 25H2 without bloatware and with support for a local account, you can use Tiny11 Builder to create a custom ISO file stripped of unnecessary apps and features. In this guide, you’ll learn how to build debloated installation media using this tool.

What is Tiny11 Builder?

“Tiny11 Builder” is a third-party script developed by community user @NTDEV to customize and streamline Windows 11 installation media. It modifies an official base Windows 11 ISO to remove most default apps and services, making the system lighter, faster, and less cluttered.

This modified image is often referred to as “Windows 11 Tiny ISO,” “Tiny11 ISO,” or “Windows 11 Lite ISO.”

The tool can automatically remove apps, such as Clipchamp, News, Weather, Xbox, Get Help, Media Player, Quick Assist, OneDrive, Copilot, Outlook, Microsoft Teams, and even Microsoft Edge. In addition to app removal, the tool includes an unattended answer file that allows you to bypass the Microsoft account requirement and create a local account during setup. It also uses the “compact” deployment flag to reduce the size of the final installation.

Why use Tiny11 Builder?

Windows 11 has steadily been adding more features and preinstalled apps with each update, many of which aren’t essential for every user. Tiny11 Builder gives you full control to create a customized and slimmed-down version of the operating system tailored to your specific needs.

It’s ideal for advanced users who prefer local accounts, minimal installations for performance or testing, virtual machines, older hardware setups, or those with privacy concerns.

The script’s creator also offers preconfigured ISO files you can download directly without running the script. The latest images have been updated with the November 2025 Security Update.

In this guide, I will show you how to download and create a Tiny11 ISO (Lite ISO) for Windows 11 25H2 in two ways. The first method outlines steps using the latest official ISO file from the Microsoft download page, and the second method outlines steps using the latest image generated by the UUP Dump script. The difference is that the UUP Dump script lets you download the most up-to-date version of the operating system, whereas the official download page is usually updated only a few times a year.

Create Windows 11 25H2 ISO using Tiny11 Builder (UUP Dump)

To download and create a custom Windows 11 25H2 ISO file using the Tiny11 Builder and UUP Dump script, follow these steps:

Open the UUP Dump page.
Click the Downloads tab.
Select the latest (x64) ISO file of Windows 11 25H2, for example, build 26200.xxx.

Quick tip: In the case of version 25H2, always choose a build equal to or higher than 26200.xxxx. If you have a Copilot+ PC or a device using an ARM processor, then download the “arm64” architecture.
Select the language for the installation in the “Language” setting.
Click the Next button.
Select the version 25H2 editions to include in the Windows 11 ISO file.
Click the Next button.
Select the “Download and convert to ISO” option.
Check the “Include updates (Windows converter only)” option.

Quick note: This step enables the script to integrate the updates, resulting in an ISO file version 25H2. As a result of this option, the process of creating the ISO file can take approximately an hour.
Click the “Create download package” button to save the tool on your computer.
Open the zip folder with File Explorer.
Click the Extract all button.
Select the location where you want to extract the files.
Click the Extract button.
Right-click the “uup_download_windows.cmd” batch file and select the Run as administrator option.

Click the latest zip file available under the “Assets” section.
Save the file containing the script on your device.
Open the folder location.
Select the Tiny11Builder-main-zip file.
Click the Extract all button.
Click the Extract button.
Open File Explorer.
Open the Windows 11 25H2 ISO folder location.
Right-click the ISO file and select the “Mount” option.
Confirm the drive letter of the virtual drive where the ISO is mounted.
Open Start.
Search for PowerShell, right-click the top result, and choose the Run as administrator option.
Type the following command to allow the Tiny11Builder script to run on the computer and press Enter:
```
Set-ExecutionPolicy unrestricted
```
Type the following command to run the Tiny11Builder script and press Enter:
```
& "C:\PATH\TO\SCRIPT\tiny11maker.ps1"
```
Quick tip: The folder includes two scripts, the “tiny11maker.ps1” that removes most default apps (recommended), and then there is the “tiny11Coremaker.ps1” script that debloats the operating system and removes Store components, disables Microsoft Defender Antivirus, and turns off the Windows Update system.
Type “R” and press Enter.
Confirm the drive letter for the Windows 11 mount point, then press Enter.
Confirm the index number for the operating system edition to create the image, then press Enter.

Quick note: Since we’re using the UUP Dump script, you may only see one or two index options, whereas the official ISO file typically includes all editions of the operating system.
Press Enter to complete the process and exit the script.
Type the following command to set the more secure PowerShell execution policy and press Enter:
```
Set-ExecutionPolicy Restricted
```

Once you complete the steps, the script will create a custom ISO file that you can use to perform a truly clean installation of Windows 11 25H2.

If you encounter an issue while running the UUP Dump script during the first part of these instructions, open the script folder, right-click the “Remove_Failure_MountDr_TempDir.cmd” file, and select “Run as administrator”. After the process completes, run UUP Dump one more time.

Also, ensure your device has sufficient free space for the script to process the files without issues or delays. Typically, the computer requires approximately 70 GB of free space on the primary drive.

Once you have the ISO file, you can mount it in a virtual machine or use tools like Rufus and Ventoy to create a bootable USB media.

Pureinfotech’s Take

Tiny11 Builder sits in a gray area that perfectly reflects what a segment of advanced users has wanted for years, including a cleaner, faster, and less opinionated version of Windows 11. By stripping out bundled apps, services, and online account requirements, it delivers a streamlined experience that feels closer to how Windows used to be.

At the same time, this level of modification comes with real trade-offs. Removing components such as Microsoft Edge, OneDrive, and the Microsoft Store, as well as security features in some configurations, can affect system stability, app compatibility, and long-term update behavior. It’s not an officially supported configuration, and that matters for security and reliability over time.

Where Tiny11 Builder makes the most sense is in controlled environments. Testing, virtual machines, lab setups, or older hardware that struggles with the full Windows 11 footprint are all valid use cases. It’s less about replacing Windows 11 and more about customizing it for specific needs.

For everyday users, however, the standard Windows 11 installation remains the safer and more complete option. Microsoft continues to tightly integrate security, AI features, and cloud services into the core experience, and removing them can limit what the system is designed to do.

Bottom line, Tiny11 Builder is a powerful customization tool, but it is best treated as a specialized solution rather than a mainstream alternative.
