Tiny11 is a third-party customization script designed to streamline Windows 11. It removes unnecessary apps, reduces system requirements, and allows installation on unsupported hardware using a local account. This guide explains how to download Tiny11 ISO for Windows 11 version 25H2 step by step.
What Is Tiny11 and Why Use It
Tiny11 is not an official Microsoft release.
It is a community-built script that modifies Windows 11 installation media.
It removes most preinstalled apps and background components.
As a result, Windows runs better on low-end or unsupported hardware.
Tiny11 also allows installation without a Microsoft account.
It supports upcoming feature updates like Windows 11 25H2.
Download the Windows 11 25H2 ISO
First, you need the official Windows 11 Insider Preview ISO.
- Open the Windows Insider Preview Downloads page.
- Sign in using your Microsoft account.
- Scroll down to the ISO download section.
- Select the latest available preview build.
At the time of writing, Windows 11 Insider Preview Build 26200 corresponds to version 25H2.
- Click Confirm.
- Select your preferred language.
- Click Confirm again.
- Download the ISO file to your computer.
Let the ISO download complete before moving to the next step.
Download the Tiny11 Builder Script
While the ISO is downloading, get the Tiny11 Builder script.
- Open the Tiny11 Builder GitHub page.
- Go to the Releases section.
- Download the latest available release.
In this case, download the ZIP package from the September 2025 release.
Extract the Tiny11 Builder Files
Once the ZIP file is downloaded:
- Open the folder where it is saved.
- Right-click the Tiny11 Builder ZIP file.
- Select Extract All.
- Click Extract again to confirm.
You now have access to the Tiny11 Builder scripts.
Mount the Windows 11 25H2 ISO
Next, mount the Windows ISO file.
- Right-click the Windows 11 25H2 ISO.
- Select Mount.
- Note the assigned drive letter.
For example, the mounted ISO may appear as drive E:.
You will need this drive letter later.
Run PowerShell as Administrator
Now, open Windows Terminal with elevated permissions.
- Right-click the Start menu.
- Select Windows Terminal (Admin).
- Open a PowerShell tab.
Before running the script, you must allow PowerShell scripts to execute.
Allow the Tiny11 Script to Run
In PowerShell, run the command to temporarily allow script execution.
Make sure you note the exact folder location of the Tiny11 Builder files.
- Right-click the extracted Tiny11 Builder folder.
- Copy the full folder path.
Now build the command using:
- An ampersand (
&) - A space
- The full script path
- The script name (
tiny11maker.ps1)
Press Enter to start the script.
Configure the Tiny11 Build Process
When prompted:
- Type R and press Enter.
- Enter the drive letter of the mounted ISO (for example, E).
- Press Enter.
Next, choose the Windows edition index:
- Index 1 → Windows 11 Home
- Index 6 → Windows 11 Pro
For this example, type 6 and press Enter.
Tiny11 Maker vs Core Maker
The Tiny11 Builder includes two scripts:
- Tiny11 Maker
- Tiny11 Core Maker
Tiny11 Maker removes most default apps.
Core Maker removes apps and additional system components.
Choose the script based on your needs.
The build process may take several minutes.
Do not close the terminal while it runs.
Complete the Process and Secure PowerShell
Once the script finishes:
- Press Enter to exit.
- Run the command to restore the secure PowerShell execution policy.
This ensures system security after script execution.
Locate the Final Tiny11 ISO
Finally, open the folder where you extracted Tiny11 Builder.
You will find the newly created Tiny11 ISO file there.
This ISO is ready to use for installation or USB creation.
Conclusion:
Tiny11 allows you to install Windows 11 25H2 on unsupported hardware.
It reduces system load and removes unnecessary applications.
Always use third-party tools carefully and at your own risk.
You now have a custom Tiny11 ISO ready for deployment.
