WhyNotWin11 for Windows

WhyNotWin11 is a free open-source tool that helps you determine whether your computer meets the system requirements for Windows 11. This lightweight program offers an alternative to Windows PC Health Check, providing more detailed insights into compatibility issues. 

It checks key system components like TPM, Secure Boot, and processor compatibility, presenting results in a clear, color-coded interface. Since Windows 11 has strict hardware requirements, this tool is useful if you are unsure if your system can upgrade. Unlike Microsoft’s official tool, WhyNotWin11 provides transparency by specifying which requirements are fulfilled, allowing you to assess potential workarounds or upgrades.

Scanning your system

WhyNotWin11 scans a computer’s hardware and compares it to Windows 11’s requirements. The tool checks the processor, RAM, TPM version, Secure Boot status, storage type, and other critical specifications. Results are displayed in a color-coded format: green for compatible components, red for unsupported ones, and yellow for borderline cases. This makes it easier to identify potential upgrade issues at a glance.

The program does not require installation and runs as a standalone executable. This makes it convenient if you want a quick system check without adding extra software to your PC. Because it’s open-source, you can verify the tool’s code on GitHub, ensuring transparency and avoiding concerns about data privacy or security.

It provides a clear and detailed compatibility assessment.  While it doesn't offer direct solutions for unsupported components, it gives you the information to understand your system's limitations. This knowledge allows you to research potential fixes and explore options like workarounds, keeping in mind that Microsoft's support for such configurations is not guaranteed.  This tool serves as an informational guide rather than a fix-it solution.

Windows 11 upgrade assessment

WhyNotWin11 provides a clearer breakdown of Windows 11’s requirements and informs you about what to upgrade, but it doesn't give detailed explanations or suggest potential fixes. Being portable and open-source is a plus if you're privacy-minded. It's useful for spotting compatibility issues, but you'll need additional research if you're looking to get around any restrictions. It's a diagnostic tool but not a one-stop solution for upgrading to Windows 11.
