Detailed Description

The tool addresses the problem of unclear upgrade blockers by scanning a system and reporting which specific requirements are not met. It checks hardware specifications like processor compatibility, RAM, storage, and firmware features, as well as software conditions that might prevent a successful Windows 11 installation. The script runs locally on the target machine and produces a detailed report of failures and warnings.

Users should choose this tool if they need to quickly diagnose why a specific PC cannot upgrade to Windows 11 before attempting installation. It suits both individual users troubleshooting their own systems and IT administrators evaluating fleet readiness across multiple machines. The tool includes update checking functionality, allowing users to verify they are running the latest detection logic. Anyone considering adoption should note that the project provides a web-based interface at its homepage for users who prefer not to run a script directly.

The project shows consistent maintenance with regular updates addressing new Windows 11 requirement changes and detection improvements. The codebase remains actively refined to handle edge cases and improve detection accuracy across diverse hardware configurations.
