Google has announced ChromeOS Flex as a free upgrade for Windows users facing the phase-out of Windows 10. This initiative, in partnership with Back Market, aims to transform unsupported laptops into secure machines at no cost, targeting the approximately 500 million Windows 10 users unable to upgrade to Windows 11 due to hardware limitations. The upgrade is free, with a nominal fee for the USB hardware required for installation. However, the USB kits are currently out of stock, and users can sign up on Back Market's website for notifications. ChromeOS Flex offers robust protection against malware, allowing older hardware to remain secure.
