How to fix “This PC can’t run Windows 11” error?

The error message ‘This PC can’t run Windows 11’ usually appears when your computer does not meet one or more of the minimum system requirements set by Microsoft. These requirements include parameters like TPM 2.0, Secure Boot, compatible processor, and sufficient RAM or storage.

• Processor: 1 GHz or faster with 2 or more cores on a compatible 64-bit processor
• RAM: 4 GB or higher
• Storage: 64 GB or larger
• System Firmware: UEFI with Secure Boot capability
• TPM: Version 2.0
• Graphics Card: Compatible with DirectX 12 or later
• Display: High definition (720p) display that is greater than 9 inches

1. Check System Compatibility

   Use the PC Health Check tool provided by Microsoft to confirm what specific requirement your device doesn’t meet.

2. Enable TPM 2.0 and Secure Boot

   Restart your PC and enter the BIOS/UEFI settings. Locate and enable both TPM 2.0 (Trusted Platform Module) and Secure Boot options, then save changes and reboot.

3. Update System Firmware

   Check your motherboard or laptop manufacturer’s website for the latest BIOS or UEFI update. Installing this update can help your system recognize TPM or other security modules correctly.

4. Bypass TPM/Secure Boot Check (Not Recommended)

   For advanced users, Microsoft allows a registry modification to install Windows 11 without TPM 2.0 or Secure Boot, but this may lead to security vulnerabilities. Proceed only if you understand the risks.

5. Use Installation Assistant or ISO File

   Run the Windows 11 Installation Assistant from Microsoft’s website, or use a properly created bootable USB drive with the Windows 11 ISO for installation.

Most users can fix the ‘This PC can’t run Windows 11’ issue by enabling the required security features or ensuring all hardware drivers and firmware are up to date. Always back up your data before performing any major system change.
