In this guide, we will modify a Windows 11 ISO using Tiny11Maker. It removes the official requirements from Windows ISOs and any unnecessary elements that “bloat” the operating system.
This will allow you to install Windows 11 on computers without TPM 2.0 or Secure Boot and with processors older than the minimum required (second-generation AMD Ryzen or eighth-generation Intel Core).
Create a Windows 11 ISO for unsupported computers
Download a copy of Windows 11 for your computer in the required version and language. You can get it from the official Windows 11 website or with Media Creation Tool.
Mount the ISO by double-clicking on it.
Download Tiny11 Maker from the GitHub repository and extract it to any folder you want.
Run the tiny11maker script. The folder also contains the tiny11Coremaker script, which creates highly abstract images of many important components. If you plan to use modified Windows 11 on your main computer for everyday use, use the tiny11maker script, as it does not modify critical components like Windows Update, Windows Recovery, or Windows Security.
Run Windows Terminal as Administrator and copy the address where the tiny11 files are located and place the terminal in the folder with the cd command.
In our case, we saved the tiny11builder-main folder in the folder where we downloaded the .zip, that is, in Downloads.
So the route is C:\Users\giorgos\Downloads\tiny11builder-main and the order we gave is cd C:\Users\giorgos\Downloads\tiny11builder-main
Now you can run the script with the command
.\tiny11maker.ps1
You will see a warning
Press R to continue. The tiny11 screen will open and you will need to provide the drive letter of the image you downloaded before pressing Enter.
In our case it is D
Select the version you want from the list – Home, Professional, Professional N or whatever you need and press Enter.
After all this, the script will proceed on its own, and in the end it will create a new ISO image for you, which you can use to install Windows 11 without any requirements.
The new ISO (tiny11.iso) has been saved in the folder where the script is located, i.e. tiny11builder-main
Important: Tiny11maker is not a pirated tool and will not activate your system. You will need a Windows 10 or 11 key to activate the installation. Make sure you select the SKU that matches your license key.
Although the press releases will range from very select to rare, I said I'd pass...because sometimes the editors hide.



Why do I get the following, no matter what drive letter I enter?
Can't find Windows OS Installation files in the specified Drive Letter..
Please enter the correct DVD Drive Letter..
Do you mean that I have the ISO in bulk on one of the disks?
I tried all 3 that I have on my system but the answer is always the above….
: (
you haven't mounted the iso
Come on, I solved it...
You simply didn't write anywhere that you first had to mount the ISO and then give it the letter that belongs to the ISO mount, for example, for me it was I. That's it...
Can't find Windows OS Installation files in the specified Drive Letter..
Please enter the correct DVD Drive Letter..
The above keeps coming up, no matter which drive I save the Win ISO to.
Why? Any help?
Thank you
Dude, I just froze when I saw the description.
Seriously, do you think the average Windows user can complete the entire process? Huh??
