Windows 11 Compatibility Checker Can Your PC Run Windows 11?

Windows 11 requires a 1GHz or faster CPU with 2 or more cores on a compatible 64-bit processor, 4GB RAM, 64GB storage, UEFI firmware with Secure Boot, TPM version 2.0, and a DirectX 12 compatible graphics card with a WDDM 2.0 driver. Meeting all these requirements is necessary for installation and ongoing feature support.

TPM 2.0 is a security module that provides hardware-based cryptographic functions, essential for features like BitLocker, Windows Hello, and overall OS integrity. Microsoft made this requirement to strengthen baseline security, reduce firmware attacks, and support upcoming security standards in the Windows ecosystem.

Enter your system’s BIOS or UEFI settings during boot (often by pressing Delete, F2, or Esc). Look for a 'Security' or 'Advanced' tab to find TPM (sometimes listed as 'PTT' for Intel or 'fTPM' for AMD) and enable it. Secure Boot is usually under 'Boot' or 'Security.' Save and exit after enabling both. Refer to your motherboard manual for model-specific steps.

Technically, it is possible to bypass some requirements via registry tweaks or using third-party scripts, but Microsoft discourages this. Unsupported installations may not receive security updates, cumulative updates, or support, and could experience stability or compatibility issues in the future.

If your CPU is not officially supported, upgrading to a compatible processor is the most reliable solution. Check Microsoft’s published lists for Intel, AMD, and Qualcomm CPUs. In some cases, a BIOS update may add support for newer CPUs, but most older CPUs will not be added to the official list.

Upgrading RAM or storage can resolve those specific requirements if that’s what your system lacks. However, you must also meet TPM 2.0, Secure Boot, and CPU compatibility. The checker will indicate if upgrading memory or adding storage is sufficient for your case.

No, not all motherboards have a header or firmware support for discrete TPM 2.0 modules. Many modern boards have firmware-based TPM (PTT or fTPM), which is sufficient if enabled. For older boards, check your manufacturer’s documentation to see if a TPM 2.0 add-on is possible.

Yes, Secure Boot is a mandatory requirement for Windows 11 installation and ongoing updates. It ensures only signed, trusted software loads during boot, protecting against rootkits and boot-level malware. Most UEFI-based systems can enable Secure Boot via firmware settings.

If your system drive has less than 64GB available, Windows 11 will not install. Free up storage by removing unused files, uninstalling programs, or moving data to another drive. The compatibility checker will flag low storage as a blocking issue and suggest remedies.

This tool uses the same core requirements and logic as Microsoft’s official checker but provides more detailed breakdowns and explanations for each component. It does not send data externally and is designed for transparency and educational value.

Yes, the compatibility checker analyzes hardware on both desktop and laptop PCs, as long as the system runs Windows and exposes standard hardware interfaces. Some ultrabooks or custom OEM devices may have proprietary firmware, but most mainstream devices are fully supported.

The checker relies on accurate hardware reporting from Windows and firmware. If components are masked (by virtualization or manufacturer restrictions), results may not reflect true hardware capability. It does not check for driver availability or application compatibility - only core OS requirements.

You can view your CPU model in Windows by opening Task Manager (Ctrl+Shift+Esc), navigating to the 'Performance' tab, and selecting 'CPU.' The model number (e.g., Intel Core i7-8700K, AMD Ryzen 5 3600) helps determine generation and compatibility. The checker automatically identifies and matches your processor.

Windows 11 requires a DirectX 12-compatible GPU with a WDDM 2.0 driver. Cards like the GTX 1050 Ti and newer generally meet this requirement, but some very old cards may not. The compatibility checker primarily focuses on CPU, RAM, storage, TPM, and Secure Boot, but GPU support should also be verified for full feature access.

Yes, the compatibility checker runs locally on your device and does not require an internet connection for analysis. No user data is sent externally, ensuring privacy and security.

No, UEFI is the modern replacement for legacy BIOS and is required for Secure Boot. Most systems from 2012 onward use UEFI. The checker identifies whether your system uses UEFI and if Secure Boot is properly configured, as legacy BIOS systems are not compatible with Windows 11.

The checker provides detailed guidance on resolving specific failures. For example, you may just need to enable a setting in firmware, upgrade RAM, or free up disk space. If your CPU is unsupported, however, a hardware upgrade will be necessary for full Windows 11 compatibility.

Windows 11 brings several performance enhancements, especially for newer hardware, such as improved scheduling for hybrid CPUs, better memory management, and new security features. While compatible systems often see some improvements, the actual performance gain varies by workload and hardware configuration.
