To ensure your hardware is compatible with the latest Windows version, first visit the official Microsoft website and look for the minimum system requirements for the version you're interested in. These requirements typically include processor speed, RAM, hard disk space, and graphics capabilities. Compare these with your system's specifications by accessing 'System Information', where you can find detailed information about your hardware, including processor, RAM, and installed graphics card. Additionally, you can use the 'Device Manager' to check the specifics of hardware components and ensure they have up-to-date drivers compatible with the new Windows version.
