Scripts to build a trimmed-down Windows 11 image - now in PowerShell!

Introduction :

Tiny11 builder, now completely overhauled.
After more than a year (for which I am so sorry) of no updates, tiny11 builder is now a much more complete and flexible solution - one script fits all. Also, it is a steppingstone for an even more fleshed-out solution.

You can now use it on ANY Windows 11 release (not just a specific build), as well as ANY language or architecture. This is made possible thanks to the much-improved scripting capabilities of PowerShell, compared to the older Batch release.

This is a script created to automate the build of a streamlined Windows 11 image, similar to tiny10. The script has also been updated to use DISM's recovery compression, resulting in a much smaller final ISO size, and no utilities from external sources. The only other executable included is oscdimg.exe, which is provided in the Windows ADK and it is used to create bootable ISO images. Also included is an unattended answer file, which is used to bypass the Microsoft Account on OOBE and to deploy the image with the /compact flag. It's open-source, so feel free to add or remove anything you want! Feedback is also much appreciated.

Also, for the very first time, introducing tiny11 core builder! A more powerful script, designed for a quick and dirty development testbed. Just the bare minimum, none of the fluff. This script generates a significantly reduced Windows 11 image. However, it's not suitable for regular use due to its lack of serviceability - you can't add languages, updates, or features post-creation. tiny11 Core is not a full Windows 11 substitute but a rapid testing or development tool, potentially useful for VM environments.

⚠️ Script versions:

• tiny11maker.ps1 : The regular script, which removes a lot of bloat but keeps the system serviceable. You can add languages, updates, and features post-creation. This is the recommended script for regular use.
• ⚠️ tiny11coremaker.ps1 : The core script, which removes even more bloat but also removes the ability to service the image. You cannot add languages, updates, or features post-creation. This is recommended for quick testing or development use.

Instructions:

1. Download Windows 11 from the Microsoft website or Rufus
2. Mount the downloaded ISO image using Windows Explorer.
3. Open PowerShell 5.1 as Administrator.
4. Change the script execution policy :

Set-ExecutionPolicy Bypass -Scope Process

Using -Scope Process you keep your original policy intact as this change only lasts for the current PowerShell session.

6. Start the script :

C:/path/to/your/tiny11/script.ps1 -ISO <letter> -SCRATCH <letter>

You can see of the script by running the get-help command.

6. Select the drive letter where the image is mounted (only the letter, no colon (:))
7. Select the SKU that you want the image to be based.
8. Sit back and relax :)
9. When the image is completed, you will see it in the folder where the script was extracted, with the name tiny11.iso

What is removed:

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!

Known issues:

• Although Edge is removed, there are some remnants in the Settings, but the app in itself is deleted.
• You might have to update Winget before being able to install any apps, using Microsoft Store.
• Outlook and Dev Home might reappear after some time. This is an ongoing battle, though the latest script update tries to prevent this more aggressively.
• If you are using this script on arm64, you might see a glimpse of an error while running the script. This is caused by the fact that the arm64 image doesn't have OneDriveSetup.exe included in the System32 folder.

Features to be implemented:

• disabling telemetry (Implemented in the 04-29-24 release!)
• more ad suppression (Partially implemented in the 09-06-25 release!)
• improved language and arch detection
• more flexibility in what to keep and what to delete
• maybe a GUI???

And that's pretty much it for now!
