Microsoft will end support for Windows 10 on October 14, 2025, encouraging users to upgrade to Windows 11. Before upgrading, users should back up their files to prevent data loss, using either an external drive or OneDrive for cloud storage. To download Windows 11, users can either install it over Windows 10 or perform a clean install using a USB flash drive with the Media Creation Tool. During installation, users can choose to preserve existing files or perform a clean install. For those hesitant to upgrade, continuing with Windows 10 poses security risks, and Linux is suggested as an alternative operating system. User-friendly Linux distributions like Linux Mint or Ubuntu are recommended for newcomers.
