Microsoft will end support for Windows 10 in one year, marking a significant milestone as the operating system reaches its end-of-life (EOL). This means no more security updates, technical support, or bug fixes, leaving users vulnerable to security threats. Windows 10 still holds a 62.7% market share, with Windows 11 at 33% and Windows 7 at 2.8%. The end of support means Microsoft will stop providing security updates, which are crucial for system protection. Users are advised to upgrade to Windows 11, switch to Linux or macOS, or opt for paid extended support. Windows 11 requires compatible hardware, while Linux and macOS offer different user experiences. Extended support is available for Windows 10 for an additional three years, mainly for enterprise users.
