The End of an Era: Windows 10’s Final Non-Security Update
After nearly a decade of service, Windows 10 has reached its end-of-life for feature updates with this month’s Patch Tuesday release. While extended security updates will continue for eligible organizations, this represents the final chapter in the operating system’s feature development journey. The update, identified as KB5066791, brings the build number to 19045.6456 for both Windows 10 22H2 and 21H2 versions.
The final Windows 10 update focuses primarily on resolving known issues that have affected users in recent months. Microsoft has addressed connectivity problems with the legacy SMBv1 protocol, specifically fixing an issue where users couldn’t connect to shared files and folders when using Server Message Block v1 over NetBIOS. This resolution directly impacts network administrators and users maintaining older network infrastructure that relies on this protocol.
Windows Autopilot and Enterprise Deployment Improvements
For enterprise users and IT administrators, the final update resolves a critical deployment issue affecting Windows Autopilot Enrollment Status Page (ESP) functionality. The patch fixes a scenario where the ESP failed to load during the Out-of-Box Experience when deploying Windows 10 version 22H2 to devices. This improvement ensures smoother enterprise deployments and reduces support overhead for organizations still implementing Windows 10 in their environments.
The networking improvements extend to NetBIOS over TCP/IP (NetBT) configurations, providing better compatibility for mixed network environments. These final tweaks demonstrate Microsoft’s commitment to ensuring stability for the millions of devices that will continue running Windows 10 during the extended security update period.
Windows 11’s Substantial Feature Update
While Windows 10 receives its swan song, Windows 11 users are treated to a comprehensive update packed with new features and improvements. The KB5066835 update for Windows 11 25H2 and 24H2, along with KB5066793 for versions 23H2 and 22H2, introduces AI-powered capabilities and significant user experience enhancements that position the operating system for future development.
The update incorporates all changes from the September 29th preview build, delivering a mature set of features that have undergone testing and refinement. Microsoft’s gradual rollout approach means users may receive the update at different times, ensuring stability and performance across diverse hardware configurations.
Enhanced User Interface and Customization Options
Windows 11 users gain new customization capabilities with movable hardware indicators for brightness, volume, airplane mode, and virtual desktops. This feature allows users to reposition these essential system indicators to different screen locations through Settings > System > Notifications. The improvement provides greater flexibility for users who prefer customized desktop layouts.
The File Explorer receives substantial enhancements, including improved integration with version control systems. When selecting repository folders, users can now view Git details such as branch information, diff counts, and last commit messages directly within File Explorer. This feature bridges the gap between development workflows and file management, creating a more integrated experience for developers and technical users.
AI-Powered Features and Productivity Enhancements
Microsoft continues to integrate AI capabilities throughout Windows 11 with the new Summarize action for Click to Do functionality. This AI-powered feature provides quick summarization of content, helping users process information more efficiently. The integration represents Microsoft’s broader strategy of embedding artificial intelligence throughout the Microsoft Windows ecosystem.
The Windows Share window receives practical improvements with the ability to pin favorite apps for quick access. This enhancement streamlines sharing workflows and reduces the time needed to locate frequently used applications. For enterprise environments, IT administrators benefit from improved taskbar pinning policies that no longer require restarting explorer.exe to apply changes, significantly reducing deployment friction.
Security and Accessibility Advancements
A major security enhancement arrives with seamless plugin passkey manager integration, allowing users to leverage third-party credential managers for passkey management. The feature requires installing a compatible credential manager application, then enabling support through Settings > Accounts > Passkeys > Advanced options. Users must complete verification using Windows Hello (face recognition, fingerprint, or PIN) before accessing existing passkeys or saving new ones.
Accessibility receives significant attention with improvements to Narrator functionality and the introduction of a modern Braille viewer. These enhancements continue Microsoft’s commitment to making Windows accessible to all users, regardless of ability or disability. The update also extends Notification Center functionality to secondary monitors, providing consistent user experience across multi-monitor setups.
Developer and Power User Tools
Developers gain a redesigned Advanced settings page (Settings > System > Advanced), which updates the previous For Developers page with improved organization and discoverability of key options. The new layout makes it easier to locate development-specific settings and configurations.
A significant addition for command-line users is the inclusion of Edit, an open-source text editor accessible directly from the command line. Users can launch the editor by opening the Terminal app and typing “edit” followed by the filename. The tool, available on GitHub, provides a lightweight editing solution for quick file modifications without leaving the command-line environment.
Gaming and Multimedia Improvements
Gaming experiences receive multiple fixes and enhancements in this update. Microsoft resolved an issue where apps and games failed to respond to input when users signed in using only a gamepad at the lock screen. The update also addresses protected content playback issues in certain Blu-ray, DVD, and digital TV apps that use Enhanced Video Renderer with HDCP enforcement.
High Dynamic Range (HDR) functionality gains stability with a fix for unexpected immediate turn-off after being enabled in Settings. Dynamic Lighting improvements address excessive CPU consumption by the Background Controller after unlocking the PC, ensuring better system performance during gaming sessions.
System Performance and Compatibility Updates
The update brings numerous performance optimizations, including support for Certificate Revocation List (CRL) partitioning in Windows Certificate Authorities. This enhancement improves security certificate management and validation processes for enterprise environments.
Compatibility changes include the removal of the ltmdm64.sys driver, meaning fax modem hardware dependent on this specific driver will no longer function in Windows. This change reflects Microsoft’s ongoing effort to modernize the Windows driver ecosystem and remove legacy components. The update also addresses third-party application security considerations through various underlying improvements.
Browser and Input Method Fixes
Chromium-based browser users benefit from a fix addressing unresponsive print preview screens, resolving a persistent issue affecting printing workflows. Windows Hello improvements include resolved setup problems for face recognition when using USB infrared camera modules, eliminating persistent error messages during configuration.
Quick Settings receives attention with a fix for PIN confirmation issues when casting from Quick Settings. The update ensures that pressing Enter properly confirms PIN entries, streamlining the casting experience for users who frequently share content to external displays.
Update Availability and Installation
All updates are available through Windows Update and the Microsoft Update Catalog. Windows 11 users can download KB5066835 for versions 25H2 and 24H2, or KB5066793 for versions 23H2 and 22H2. Windows 10 users should look for KB5066791, available for all editions of version 22H2 and specific editions of version 21H2.
