How can I force to install Windows 11 on unsupported PC?

Don't use Rufus. The USB is not bootable and now the USB is not recognized by my computer. It is a brand new SanDisk 64GB USB, lol

A bit late, but no need for all the steps and voodoo in the comments, just use Rufus to create an installer USB and enable the right settings, it will take care of the rest for you.

Or even better... Use Chris Titus's tool to create a MicroWin installer.

It sounds like a perfect time to go MAC... If MS only really knew how they are hated by the masses.  I am hungry for an APPLE about now

Simply replace appraiserres.dll to install Windows 11 on unsupported hardware for unsupported PC and no TPM/Secure Boot.

Best for: Installing from an ISO directly

1. Download the Windows 11 ISO (Microsoft’s site).

2. Mount the ISO (double-click) or extract it.

3. Navigate to:

\sources\appraiserres.dll

4. Delete or rename this file.

5. Create a bootable USB with the modified files (using Rufus or Media Creation Tool).

Install Windows 11 on this unsupported PC and it won't check for TPM.

If you're planning to install Windows 11 on unsupported hardware and want to explore alternative boot methods or use unofficial scripts, these approaches can help bypass the standard hardware requirements. However, they are advanced, carry risks, and are not officially supported by Microsoft.

Considerations:

• These modifications can cause system instability or update issues.
• Unofficial patches might introduce vulnerabilities.
• Microsoft may block or prevent updates on systems running patched installations.
• Bypassing hardware requirements may violate Microsoft's licensing terms.

Final Advice:

• Only attempt these methods if you are experienced with system internals, scripting, and ISO modification.
• Always backup your data before installing Windows 11 on unsupported hardware.
• Test thoroughly in a non-critical environment first.
• Consider hardware upgrades or sticking with supported configurations for a more stable experience.

WinUpdateMate is a third-party tool designed to help users bypass Windows 11's strict hardware requirements, including TPM 2.0, Secure Boot, and CPU checks. It simplifies the process of modifying the Windows 11 installation files to allow installation on unsupported PC.

Key Features of WinUpdateMate

TPM 2.0 Bypass – Lets you install Windows 11 even without a TPM chip.

Secure Boot Bypass – Works on systems without Secure Boot.

CPU Compatibility Fix – Supports older CPUs (e.g., Intel 6th/7th Gen, AMD FX).

RAM Check Removal – Allows installation on PCs with less than 4GB RAM.

User-Friendly GUI – Easier than manual registry or ISO modifications.

How Does WinUpdateMate Work?

It modifies the Windows 11 installation files (ISO/USB) to:

1. Disable hardware checks during setup.
2. Patch system files to prevent blocking unsupported hardware.

WinUpdateMate is a convenient tool for installing Windows 11 on unsupported hardware, but use it cautiously. For maximum security, consider upgrading hardware or sticking with Windows 10 until official support ends (2025).

This is a very common case as many old PC does not have TPM 2.0.

TPM (Trusted Platform Module) 2.0 is a security chip (either physical or firmware-based) that provides hardware-level encryption for:

• Secure storage of passwords, encryption keys, and certificates
• Protection against malware and hacking attempts
• BitLocker drive encryption support
• Secure boot verification

Windows 11 requires TPM 2.0 to ensure better security against modern threats like ransomware and firmware attacks.

TPM 2.0 is available 2014. This means the motherboard should be 2014 or later in order to run Windows 11. 

How to install Windows 11 on unsupported PC

1. Ensure Windows 10 is activated (21H2 or later).

2. Download the Windows 11 ISO and mount it.

3. Open Setup.exe inside the ISO.

If blocked, open Command Prompt (Admin) and run:

setup /product server

This will bypasses compatibility checks.

4. Follow the installer to install Windows 11 on this unsupported hardware without TPM 2.0 and unsupported CPU.

To upgrade your unsupported PC to Windows 11 for free, despite the hardware not meeting the official requirements (notably the lack of TPM 2.0), you can try bypassing the hardware check during installation. Here's a step-by-step guide to help you install Windows 11 on unsupported hardware:

1. Create a Windows 11 Installation Media
2. Modify the Registry or Use a Registry Hack During Setup

* Boot from the USB installer.
* When the installer reaches the "This PC can't run Windows 11" screen, press Shift + F10 to open Command Prompt.
* Type regedit and press Enter to open the Registry Editor.
* In Registry Editor, navigate to:
     HKEY_LOCAL_MACHINE\SYSTEM\Setup
* Create a new key:
    Right-click on Setup, select New > Key, name it LabConfig.
* Inside LabConfig, create two DWORD (32-bit) values:
   BypassTPMCheck and set its value to 1.
   BypassSecureBootCheck and set its value to 1 (if needed).
* Close Registry Editor and Command Prompt.
* Continue with the installation process.
Note: For some builds, you might need to also bypass CPU checks. You can add:
    SkipTPMCheck = 1
    SkipSecureBootCheck = 1
    SkipCPUCheck = 1

3. Alternatively, Use a Registry File
To install Windows 11 on unsupported hardware. Some users create a .reg file with the bypass settings and run it during setup. Example content for bypass-windows11.reg:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\Setup\LabConfig]
"BypassTPMCheck"=dword:00000001
"BypassSecureBootCheck"=dword:00000001
"SkipCPUCheck"=dword:00000001

Save the file, then run it during setup by pressing Shift + F10, typing regedit, and importing the .reg file.

4. Proceed with Installation
After applying the registry modifications, continue with the installation. The setup should now proceed without hardware check errors.

5. Post-Installation
    Once installed, you might need to disable or enable certain features.
    Keep in mind that updates or some features might not work properly.
