TejOS is a free, open-source tool that helps you create a custom Windows 11 installation file (called an ISO) that is faster, lighter, and free from unnecessary apps and services that Microsoft includes by default. Think of it as a "slim-down" for Windows 11.
If your computer feels slow, has too many background apps, or you simply want a clean start with Windows 11, TejOS is your solution. It automatically removes bloatware, disables tracking, and even helps you install Windows 11 on computers that don't officially meet Microsoft's hardware requirements.
Best of all? You don't need to be a tech expert. TejOS does the hard work for you with simple commands.
- 🚫 Removes Bloatware – Deletes pre-installed apps like Candy Crush, Xbox Game Bar, and other unnecessary programs.
- ⚡ Speeds Up Your PC – Disables background services that slow down your system and consume RAM.
- 🔓 TPM & Secure Boot Bypass – Allows installation of Windows 11 on older PCs that lack TPM 2.0 or Secure Boot support.
- 🛡️ Privacy Focused – Turns off telemetry and data collection features.
- 📦 Creates a Custom ISO – Produces a ready-to-use Windows 11 installation file that you can save or share.
- 🔄 Works with Latest ISOs – Compatible with the most recent Windows 11 releases from Microsoft.
- 💻 100% Open Source – Free to use, modify, and distribute. No hidden fees or subscriptions.

The download is completely free. You'll see a green "Code" button on the page—click it, then select "Download ZIP" to get the files.
Once the ZIP file is downloaded, right-click it and choose "Extract All." This will create a folder named TejOS on your computer. Open that folder—you'll see a PowerShell script file (usually named TejOS.ps1 or similar).
You'll need an official Windows 11 ISO file. If you don't have one, download it from Microsoft's website (search "Download Windows 11 ISO" and follow their instructions). Save this ISO file somewhere easy to find, like your Desktop.
- Right-click the TejOS script file and select "Run with PowerShell."
- If Windows shows a security warning, click "Yes" to allow it.
- Follow the on-screen prompts:
- When asked, browse to and select your Windows 11 ISO file.
- Choose where you want the new, debloated ISO to be saved (e.g., Desktop).
- Select which optimizations you want (we recommend keeping all defaults).
- Press Enter to start the process. TejOS will now work its magic—this may take 10–30 minutes depending on your computer.
Once TejOS finishes, you'll have a brand-new ISO file. You can:
- Burn it to a USB drive using a free tool like Rufus (search "Rufus USB tool" to download).
- Mount it by double-clicking the ISO file, then running
setup.exeto upgrade your current system.

TejOS uses two powerful Windows built-in tools:
- PowerShell – A command-line tool that automates tasks on Windows.
- DISM – A system tool that manages Windows images and components.
TejOS combines these to:
- Open your Windows 11 ISO file.
- Remove unnecessary packages and apps.
- Disable unwanted features and services.
- Apply the TPM/Secure Boot bypass so older hardware can install it.
- Save everything as a new, optimized ISO.
You don't need to understand the technical details—just run the script and let it do its job.
Yes. It's open source, meaning anyone can inspect the code. It only modifies the Windows 11 installation file, not your current system. Your existing files and programs are untouched.
No. TejOS doesn't activate or crack Windows. You still need a valid Windows 11 license key to activate after installation. It just removes extra components.
TejOS includes a TPM and Secure Boot bypass, so you can install Windows 11 on older computers that Microsoft officially says aren't compatible. This is a major advantage over the standard installation.
Typically 10–30 minutes, depending on your computer's speed and the size of the ISO.
No. The script asks simple questions and provides clear instructions. If you can click "Next" on a wizard, you can use TejOS.
- "Execution policy" error? Right-click the script and choose "Run with PowerShell." If that fails, open PowerShell as Administrator and type:
Set-ExecutionPolicy Bypass -Scope Processthen run the script again. - Antivirus warning? Some antivirus programs flag PowerShell scripts. Add the TejOS folder to your antivirus exclusions or temporarily disable real-time protection while running.
- ISO not found? Make sure your ISO file is valid and not corrupted. Try re-downloading from Microsoft.
