About this ISO

This Windows 11 ISO is prepared to bypass TPM and Secure Boot checks, allowing installation on legacy BIOS and older UEFI systems. It uses an installation flow compatible with most older CPUs and is ideal for users who want a straightforward upgrade or clean install on unsupported machines.

Note: This ISO is intended for installation/testing purposes only. Always use a legitimate Windows license for activation. Do not distribute commercially modified ISOs that violate licensing terms.

Who should use this

• Users with older laptops/desktops that lack TPM 2.0 or Secure Boot.
• Technicians who need a quick installer for legacy devices.
• People who want to test Windows 11 on unsupported hardware without changing BIOS settings.

Key features

• ✅ Bypasses TPM 2.0 & Secure Boot checks
• ✅ Works on legacy BIOS and older UEFI systems
• ✅ Clean installation process — same GUI as official Windows 11
• ✅ Based on official Microsoft source with installer compatibility adjustments

Quick install guide

1. Download the ISO using the link below.
2. Create a bootable USB with Rufus, ImgBurn, or BalenaEtcher (USB ≥ 8 GB).
3. Boot the target PC from the USB drive (use Boot Menu or change BIOS boot order).
4. Proceed with Windows installation like normal. Choose custom/install options as needed.
5. After install, run Windows Update and install appropriate drivers for your hardware.

Warning: Back up all important data before installing. Installing an OS will erase data on the target partition if you choose a clean install. Use this ISO at your own risk.

FAQ — quick answers

Will this void warranty? No — but modifying software or changing OS may affect manufacturer support. Check your warranty terms.

Is activation required? Yes — a valid Windows license is required for activation. This ISO does not bypass licensing requirements.

Can I revert to Windows 10? Yes — keep a Windows 10 recovery USB or backup image to restore your system if needed.

Advanced tips

• If Setup refuses to continue, try disabling Secure Boot during installation, then re-enable it afterward if supported.
• Use Rufus' "Windows To Go" or "Image mode (DD)" options carefully — for typical installs use the default recommended settings.
• If your image contains install.esd instead of install.wim, you can convert using DISM (on a modern Windows PC) before creating the USB.

Attribution & resources

• Windows ISOs — always prefer official Microsoft downloads for source files.
• Rufus — recommended for creating bootable Windows USB drives.
• 7-Zip — useful for extracting ISO contents if you need to inspect files.
