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

Fix Windows 11 compatibility check failures from PC Health Check tool when hardware does not meet minimum CPU, RAM, TPM, or Secure Boot requirements. This guide covers everything you need to know about this topic, including common causes, step-by-step solutions, and answers to frequently asked questions.

Here are the key things to understand: 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. Understanding these fundamentals will help you diagnose and resolve this issue more effectively.

The most common reasons this occurs include: 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. Identifying the root cause is the first step toward finding the right solution.

To resolve this, follow these recommended steps: Run PC Health Check tool to identify exactly which requirements are not met. Enable TPM 2.0 and Secure Boot in BIOS settings (most common fix). Convert MBR disk to GPT without data loss using: mbr2gpt /validate then mbr2gpt /convert. Check if your CPU is on the supported list at Microsoft's Windows 11 requirements page. If CPU is unsupported, consider the registry bypass (LabConfig) for unsupported hardware installation. If these steps do not resolve the issue, consider consulting additional resources or a qualified professional.
