Microsoft will end support for Windows 10 on October 14, 2025. After this date, users will no longer receive security updates, customer support, or upgrades. While Windows 10 will still function, the lack of updates will leave it vulnerable to malware and security breaches, similar to older, unsupported operating systems like Windows XP. Users are advised to consider upgrading to a newer version of Windows or exploring alternative operating systems to maintain system security and receive ongoing support.
