Windows 11 Compatibility Check Failed — PC Does Not Meet System Requirements

Warningsystem

Overview

Fix Windows 11 compatibility check failures from PC Health Check tool when hardware does not meet minimum CPU, RAM, TPM, or Secure Boot requirements.

Key Details

  • Windows 11 requires: 64-bit 1GHz+ dual-core CPU, 4GB RAM, 64GB storage, TPM 2.0, Secure Boot, UEFI
  • Only specific CPU models are officially supported (Intel 8th gen+, AMD Ryzen 2000+, Qualcomm 7c+)
  • PC Health Check tool reports which specific requirements are not met
  • Some older CPUs that meet performance requirements are still not on Microsoft's compatibility list
  • GPT disk partition style is required — MBR disks must be converted

Common Causes

  • CPU not on Microsoft's official supported processor list despite meeting performance specs
  • TPM 2.0 disabled in BIOS or not present on the system
  • Disk using MBR partition style instead of GPT required for UEFI boot
  • Secure Boot disabled or system booting in Legacy BIOS mode instead of UEFI

Steps

  1. 1Run PC Health Check tool to identify exactly which requirements are not met
  2. 2Enable TPM 2.0 and Secure Boot in BIOS settings (most common fix)
  3. 3Convert MBR disk to GPT without data loss using: mbr2gpt /validate then mbr2gpt /convert
  4. 4Check if your CPU is on the supported list at Microsoft's Windows 11 requirements page
  5. 5If CPU is unsupported, consider the registry bypass (LabConfig) for unsupported hardware installation

Frequently Asked Questions

Microsoft's compatibility is based on specific CPU models, not just performance. Older CPUs (Intel 7th gen, AMD Ryzen 1000) are excluded due to driver compatibility and security feature support, even if they are fast enough.
