Tiny11 Builder lets you create a custom Windows 11 26H2 installation ISO using a graphical interface or PowerShell scripts. The tool removes unwanted preinstalled apps and components, lets you bypass the Microsoft account requirement, and helps you create a slimmer Windows installation. In this guide, you’ll learn how to use Tiny11 Builder to create your own customized Windows 11 26H2 installation media.

Since Windows 11 26H2 is now available, you can download the official installation ISO from Microsoft’s Windows 11 download page and use it as the source for your custom image.

What is Tiny11 Builder?

Tiny11 Builder is a third-party Windows customization tool created by community developer @NTDEV. The project originally relied on PowerShell scripts to customize Windows installation media, but it now also offers a graphical application built with WinUI 3. The new app uses its own C# image-building engine rather than simply providing a graphical interface for the original scripts.

The application offers three build modes, Tiny11, Tiny11 Core, and Custom, giving you different levels of control over the installation image. You can select an official Windows ISO, choose an edition, configure the components to remove, review your selections, and build a customized installation image.

Depending on the selected mode and options, Tiny11 Builder can remove apps and components such as Clipchamp, News, Weather, Xbox, OneDrive, Microsoft Edge, and other bundled software. It also supports customizing Windows features, services, drivers, language components, and other system packages.

The tool helps you create a lighter installation and configure Windows setup to bypass the Microsoft account requirement. However, the available options and their effects depend on the build mode you choose.

Why use Tiny11 Builder?

Windows 11 includes preinstalled apps and components that not everyone needs. Tiny11 Builder gives you more control by letting you remove unwanted software and create a customized version of the operating system.

The new graphical application makes the process more accessible with a guided workflow, progress tracking, saved configurations, and more granular component selection. If you prefer working in the terminal, you can continue using the original PowerShell scripts.

Tiny11 Builder is useful for advanced users who prefer local accounts, want a minimal installation for testing, need customized images for virtual machines, or want more control over the software included in their Windows installation media.

However, choose your build mode carefully. Tiny11 Core removes additional components, disables Windows Update and Microsoft Defender, and removes Windows Recovery Environment support. These changes make it unsuitable for everyday computers. For a regular installation, use Tiny11 or Custom mode and review the components you plan to remove.

In this guide, I will show you how to download and create a Tiny11 ISO (Lite ISO) for Windows 11 26H2.

FAQs about creating Windows 11 26H2 ISO using Tiny11 Builder

Important: It’s recommended to create a backup of your computer before installing this custom version of Windows. You have been warned.

Create Windows 11 26H2 ISO using Tiny11 Builder (script)

To download and create a custom Windows 11 26H2 ISO file using the Tiny11 Builder, follow these steps:

Open the Microsoft Support website.
Select the Windows 11 option under the “Download Windows 11 Disk Image (ISO) for x64” section.
Click the Confirm button.
Select the installation language.
Click the Confirm button.
Click the Download button to save the Windows 11 26H2 ISO file.
Open the Tiny11Builder GitHub page.
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 zip file.
Click the Extract all button.
Click the Extract button.
Open File Explorer.
Open the Windows 11 26H2 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 -Scope CurrentUser
```
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, tiny11maker.ps1, which removes most default apps and is the recommended option, and tiny11Coremaker.ps1, which further debloats the operating system by removing Store components, disabling Microsoft Defender Antivirus, and turning off Windows Update.
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 26H2.

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, make sure your device has enough 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.

(Option 1) Choose the Tiny11 option for the original cleanup and debloat of Windows 11.

Quick note: I’ll continue with this option for the purpose of this guide.
(Option 2) Choose the Tiny11 Core option if you want to remove Windows Update, WinRE, and disable Microsoft Defender.

Quick note: This option is recommended only for virtual machines for testing.
(Option 3) Choose the Custom option if you want to select which items to remove from the operating system.

Quick note: This option is only recommended for technical users who understand the function of the component.

Click the Build button to start the process.
Click the Build button one more time.

After you complete the steps, you’ll have a debloated Windows 11 ISO file.

Pureinfotech’s Take

I see Tiny11 Builder as a niche tool rather than something every Windows user should use. If your goal is to install Windows 11 on your main computer, I’d still stick with Microsoft’s official ISO. However, if you’re building a virtual machine, testing software, experimenting with the operating system, or simply want to see how Windows 11 runs without many of the built-in apps, Tiny11 Builder is a practical option.

Over the years, Windows has continued to ship with more preinstalled apps and services, and not everyone wants or needs them. Tiny11 Builder gives advanced users a straightforward way to trim down the installation without having to download a modified ISO from an unknown source. Just remember that removing components can affect compatibility, so I wouldn’t use a debloated installation on a production machine unless I understood the trade-offs.

Would you use a debloated version of Windows 11, or do you prefer Microsoft’s standard installation? Let me know in the comments.
