Google, in collaboration with refurbished electronics retailer Back Market, is offering a USB memory stick that allows users to install ChromeOS Flex for free, providing an alternative to Windows 10 and addressing the end of support for the operating system. The ChromeOS Flex USB Kit simplifies the installation process and aims to extend the lifespan of aging PCs, potentially preventing millions of functioning devices from being discarded. As of October 14, 2025, Microsoft ceased all support for Windows 10, leaving vulnerabilities unaddressed. Approximately one-third of Windows devices still run on Windows 10, and users can opt for an additional year of updates at a cost of around £22. ChromeOS Flex has lower system requirements than Windows 11 but lacks features like Android app installation. It helps ensure security updates for existing devices and contributes to environmental sustainability by reducing electronic waste and carbon emissions associated with new device manufacturing. The physical kit is priced at around €3 and is reusable.
