As of my last knowledge update in January 2022, Microsoft doesn't typically sell "bundle keys" for Windows. When purchasing a Windows license, you typically acquire a product key that corresponds to a specific edition of Windows (e.g., Home or Pro). These keys are usually sold individually or as part of a device (pre-installed by the manufacturer). If there have been changes or new offerings related to Windows bundle keys after my last update, I recommend checking the official Microsoft website or contacting Microsoft directly for the most accurate and up-to-date information.

Windows 10 Home is suitable for general users who don't require advanced business features. It provides a familiar interface, supports a wide range of applications, and is commonly found on consumer laptops and desktops.
