Windows 10 has reached the end of its mainstream support, which means most users will no longer get new features or regular updates. Microsoft recommends upgrading to Windows 11, but users can also buy extended security updates to keep their system protected. In this post, we’ll cover the latest updates for Windows 10, specifically versions 22H2 and 21H2, including what they fix and when they’re released.

Latest Windows 10 Updates and Their Details

Microsoft releases updates for Windows 10 versions 22H2 and 21H2 together. Keep in mind that as of November 2025, only devices enrolled in the Windows 10 Extended Security Updates (ESU) program or those with specific enterprise licenses will continue to receive updates. This means most regular users will no longer get official updates unless they switch to newer versions or have special arrangements.

One of the recent updates is KB5075912, released on February 10, 2025. This update mainly addresses bugs, including an issue with folder renaming in File Explorer. Previously, custom folder names wouldn’t display correctly because the LocalizedResourceName setting was ignored. With this fix, custom folder names now show as intended. The update also improves how devices receive new Secure Boot certificates, ensuring a safer and phased rollout based on device readiness.

Important Security and Stability Fixes

Another key update is KB5078129, which came out out-of-band on January 24, 2026. This update tackles a bug where some applications would become unresponsive or error-prone when opening or saving files to cloud storage services like OneDrive or Dropbox. It specifically fixes issues affecting Outlook, where PST files stored on OneDrive caused Outlook to hang or fail to reopen, leading to missing emails or sent items. Applying this update helps restore smooth cloud file handling and Outlook stability.

There’s also KB5077796, released on January 17, 2026, which addresses sign-in problems during Remote Desktop sessions. Some users experienced failures when trying to connect remotely, affecting authentication processes. This fix improves the reliability of remote connections, making it easier for users to access their work or home computers from afar without interruptions.

These updates highlight Microsoft’s ongoing efforts to improve security and fix bugs, especially as Windows 10 reaches the end of mainstream support. It’s important for IT teams and users to stay aware of these patches, apply them promptly, and monitor for any issues during the rollout.

Overall, Windows 10 users who want continued security updates should consider enrolling in the ESU program or upgrading to a newer version of Windows. Regular updates help keep systems safe from vulnerabilities and ensure smoother operation. Staying informed about the latest patches is key to maintaining a secure and reliable computing environment.
