Microsoft has released the KB5068781 update, marking the first Windows 10 extended security update since the operating system's official support ended on 2025-10-14. This move aims to address a bug affecting some users' enrollment in the Extended Security Updates (ESU) program.
Enrollment and Availability
The final Windows 10 cumulative update was released last month, and the system no longer receives free security updates, pushing consumers and businesses towards Microsoft's ESU program. Consumers can access the ESU by paying $30, using 1,000 Microsoft reward points, or with Windows Backup synchronization. In the European Economic Area, free ESU is available by logging in with a Microsoft account, or for $30 when using a local account. Businesses can enroll in ESU for three years, incurring a $427 cost per device.
Security and Bug Fixes
The KB5068781 update is crucial as it not only resolves the enrollment issue but also addresses key security flaws. It upgrades Windows 10 ESU to build 19045.6575 and Windows 10 Enterprise LTSC 2021 to build 19044.6575. Included are Patch Tuesday updates that fix 63 vulnerabilities, along with a specific patch for an elevation-of-privilege flaw under active exploitation.
Implementation and Impact
Microsoft has mandated the installation of this update, which will automatically prompt a restart. Users can manually install it by navigating to Settings > Windows Update and selecting 'Check for updates.' This update effectively ensures continued protection and functionality for entities relying on Windows 10 ESU and LTSC. Microsoft has reported no known issues with this update.
