Support for Windows 10 officially ends on 14 October 2025, after which Microsoft will stop providing free security updates and patches. The Windows 10 Extended Security Updates (ESU) program allows users to continue receiving critical security updates until 13 October 2026. To qualify for ESU, PCs must run Windows 10, version 22H2, be one of the specified editions (Home, Pro, Pro Education, or Workstations), have the latest updates installed, and be signed in with a Microsoft account that has administrator rights. Enrollment can be done at no cost if settings are synced with a Microsoft account, by redeeming 1,000 Microsoft Rewards points, or through a one-time purchase. Each ESU license covers up to 10 devices linked to the same Microsoft account. If users do not enroll in ESU, their PCs will not receive security updates, increasing vulnerability to threats. Upgrading to Windows 11 is recommended for long-term security, but many older PCs may not meet the necessary hardware requirements. After October 2026, even those enrolled in ESU will lose official security support.
