💻 Windows 11 System Requirements: Full Compatibility Guide (2026)

Before upgrading to Windows 11, it’s essential to check whether your device meets the official system requirements. Microsoft introduced stricter hardware rules focused on security, performance, and reliability.

📌 Quick Summary:
  • Requires TPM 2.0 and Secure Boot
  • Minimum 4 GB RAM and 64 GB storage
  • Only supported CPUs (modern 64-bit)

📊 Minimum System Requirements

  • ⚙️ Processor: 1 GHz or faster, 2+ cores (64-bit)
