Windows 10 has reached the end of its mainstream support, which means Microsoft is no longer rolling out new features or regular security updates for most users. The company recommends upgrading to Windows 11 for the latest features and improvements. For those who want to keep Windows 10, there’s an option to buy extended security updates, known as ESU, which provides security patches but no new features. This guide covers the latest updates for Windows 10 versions 22H2 and 21H2, including their release dates and key details.

Latest Windows 10 Updates and Their Details

Microsoft releases updates for Windows 10 versions 22H2 and 21H2 together, ensuring both are kept secure and stable. The most recent update, KB5082200, was released on April 14, 2026, and applies only to devices enrolled in the Windows 10 ESU program or with specific Enterprise licenses. This update addresses several bugs, such as fixing a login issue with Microsoft accounts and enhancing protection against phishing attacks that use Remote Desktop files. It also introduces a new feature that reports the status of Secure Boot in Windows Security settings, giving users a clearer picture of their device’s security posture.

The update also includes a variety of security patches to fix vulnerabilities across the system. Microsoft’s Security Update Guide provides detailed information about these patches. Because security updates are critical, they should be installed promptly. Users and IT teams should monitor for any issues after applying the update, but generally, it’s recommended to keep systems protected with the latest security patches.

Older Updates and What They Offer

Earlier updates, like KB5078885 released on March 10, 2026, also focused on security improvements. This update expanded device coverage for Secure Boot certificates, targeting systems that demonstrate successful update signals. This helps ensure that only trusted devices receive security certificates, maintaining system integrity. Like the latest update, it contains numerous security patches designed to fix known vulnerabilities and improve overall security.

These updates are part of Microsoft’s ongoing efforts to keep Windows 10 secure for enterprise and individual users still on older versions. Since the support window is closing, businesses and users are encouraged to plan their upgrade to Windows 11 or consider extended security options for Windows 10. Regularly checking for updates and installing them quickly helps protect devices from potential threats.

In summary, while Windows 10 is nearing the end of its mainstream support, updates like KB5082200 and KB5078885 continue to improve security and fix bugs. For best security practices, applying these updates as soon as possible is recommended, especially for devices enrolled in ESU or running supported enterprise licenses. Staying informed about the latest patches ensures your system remains protected even as support phases out.
