[2025 Guide] Install Windows 11 24H2 on Unsupported PCs (Bypass Compatibility Check)

Introduction

Main explanation: In the summer of 2025, Microsoft’s Windows 11 version 24H2 has increased its hardware compatibility checks.

Note: Older CPUs and systems without TPM 2.0 can frequently get stuck at the “This PC can’t run Windows 11” screen.

What is a “compatibility check bypass tool”?

Main explanation: Normally, Windows 11’s installer verifies CPU generation, TPM, Secure Boot, UEFI, RAM, and storage. If any requirement is missing, installation halts.

Note: A bypass tool temporarily skips these checks during installation, letting the setup proceed on unsupported machines.

Why can’t the 24H2 update be installed on many PCs?

Main explanation: These are set to ensure strong security, system stability, and readiness for next-gen AI features such as Windows Copilot.

Note: Older PCs often lack TPM 2.0, Secure Boot, or UEFI, causing automatic installation blocks.

Three ways to bypass the compatibility check

Method ①: Use a bypass-capable tool (Beginner‑friendly)

Main explanation: Tools like Rufus, Ventoy, or Tiny11 Builder include built‑in options to skip TPM, Secure Boot, and CPU checks when creating a USB installer.

Example: Using Rufus

1. Download the latest Rufus from its official site.
2. Obtain the Windows 11 24H2 ISO.
3. When creating the USB installer, tick the box to “Skip TPM, Secure Boot, and CPU checks”.
4. Create the USB and boot from it to start installation.

Main explanation: Rufus edits the ISO’s registry/settings, effectively bypassing checks without hacking the official installer.

Note: Always download Rufus from its official website to avoid fake or malware‑infected versions.

Method ②: Manual registry tweak (Intermediate)

Main explanation: During setup, press Shift+F10 → regedit to edit the registry manually:

HKEY_LOCAL_MACHINE\SYSTEM\Setup\LabConfig

Create DWORD values:

• BypassTPMCheck = 1
• BypassSecureBootCheck = 1
• BypassCPUCheck = 1

Close regedit and continue installation.

Main explanation: This disables the installer’s hardware compatibility checks mid‑setup.

Note: Future Windows builds might ignore these registry tweaks, so always check for updated bypass methods.

Method ③: Offline account bypass (for MSA enforcement)

Main explanation: Windows 11 24H2 increasingly requires a Microsoft Account during setup. To bypass:

OOBE\BYPASSNRO

This command (entered via Shift+F10) restarts setup and re‑enables local account creation.

Note: Useful for users who prefer a local account or have limited internet access during installation.

Risks of installing via bypass

• No official support in the future
• Security or AI features may not work properly
• Driver or peripheral compatibility issues

Main explanation: Though bypass allows installation, unsupported PCs may experience functionality issues.

Note: Back up important data before proceeding; it’s especially crucial on older hardware.

Why go through the trouble?

Main explanation: Windows 11 24H2 introduces AI enhancements, better power efficiency, stronger security standards, and prepares for Copilot and other AI features.

Note: Some users want to prolong the life of their older PCs by accessing these new features rather than buying new hardware.

Common post-bypass issues

• Older peripherals (e.g. printers, webcams) may fail
• Sleep/resume may be unstable due to BIOS/UEFI quirks
• AI-powered features may not function fully
• Windows Update might fail or stall

Main explanation: These aren’t guaranteed to occur, but are reported frequently.

Note: Understand that the resulting environment won’t match officially supported systems in reliability.

Are these bypass tools safe?

Main explanation: Rufus and Ventoy are widely used and generally trustworthy—but only when downloaded from their official websites.

Note: Avoid “fake Rufus” or unofficial sites that may contain malware.

Conclusion

Main explanation: Here’s a summary of the three methods:

Main explanation: Though Microsoft may tighten restrictions further, these bypasses are currently effective for installing 24H2 on unsupported PCs.

Note: Proceed at your own risk. Always back up data and stay informed through updated guides.
