Microsoft has officially ended support for its Windows 10 operating system on October 14, 2025. This means that computers running on Windows 10 will no longer receive free security updates, non-security updates, or assisted support, potentially leaving them vulnerable to security risks like viruses and malware. The end of support affects a substantial number of users, as a significant percentage of Windows devices were still running on Windows 10 in the lead-up to this date. Microsoft is urging users to upgrade to Windows 11 to ensure their devices remain secure and supported. For users with machines that do not meet the system requirements for Windows 11, Microsoft is offering an Extended Security Updates (ESU) program, which will provide security patches for up to three years for a fee. This move is seen as a significant push to transition the user base to the newer operating system and its integrated AI experiences.
