Introduction: A New Step Toward a More Intelligent Windows Experience
Microsoft continues its aggressive evolution of Windows 11 with the release of KB5101684, a major optional preview cumulative update designed to improve stability, usability, accessibility, and hardware compatibility across Windows 11 versions 24H2 and 25H2.
Unlike traditional security-focused Patch Tuesday releases, preview updates such as KB5101684 serve as a testing ground for improvements that will eventually become part of future mandatory updates. They allow Microsoft to gather feedback, identify hidden problems, and refine new features before wider deployment.
The July 2026 preview update arrives with dozens of fixes and improvements, including major upgrades to File Explorer, Voice Access, Windows Hello Enhanced Sign-in Security, touchpad controls, Windows Search, AI components, networking reliability, and enterprise management features.
With more than 40 fixes included, KB5101684 reflects Microsoft’s broader strategy: Windows is no longer just an operating system receiving occasional patches. It is becoming a continuously evolving platform where artificial intelligence, security, accessibility, and cloud management are deeply integrated.
Windows 11 KB5101684 Overview: What Users Need to Know
Microsoft released KB5101684 as an optional non-security preview cumulative update for Windows 11 24H2 and Windows 11 25H2.
The update brings:
Windows 11 24H2 build 26100.8973
Windows 11 25H2 build 26200.8973
42 bug fixes and feature improvements
File Explorer enhancements

Users can install KB5101684 through:
Settings → Windows Update → Check for Updates → Download and Install
The update is also available through the Microsoft Update Catalog for administrators who prefer manual deployment.
Why Microsoft Released KB5101684 Before Patch Tuesday
Microsoft’s preview update strategy has become an important part of Windows development.
Instead of releasing every improvement during security updates, Microsoft separates feature testing from emergency security fixes.
This approach allows:
IT administrators to test changes before company-wide deployment.
Microsoft to collect telemetry data.
Businesses to avoid unexpected compatibility problems.
Users to receive improvements faster.
For enterprise environments, optional updates provide an early warning system.
Organizations running thousands of Windows devices can evaluate changes before they become mandatory, reducing operational disruption.
File Explorer Receives Major Improvements
File Explorer is one of the biggest beneficiaries of KB5101684.
Microsoft continues improving the Windows file management experience by addressing long-standing usability problems.
Better File Size Display
Previously, Windows File Explorer often displayed file sizes only in KB, forcing users to mentally calculate larger values.
The new update introduces clearer size formatting:
KB
MB
GB
This small change significantly improves usability, especially for users managing large files, backups, and professional media projects.
Improved Tab Navigation
Users can now middle-click folders from the Address Bar and Home page to open them in new tabs.
This creates a more consistent browsing experience similar to modern web browsers.
Better Thumbnail Quality
Microsoft also improved thumbnail rendering in the Recommended section, making previews sharper and easier to recognize.
DFS Drive Security Fix
A serious usability problem involving Distributed File System (DFS) mapped drives has also been fixed.
Previously, files stored on DFS locations could incorrectly receive the Mark of the Web security warning after devices disconnected and reconnected to networks.
This caused Windows to display warnings such as:
“The file you are attempting to preview could harm your computer.”
KB5101684 corrects this behavior.
Voice Access Becomes Smarter With AI-Powered Voice Isolation
One of the most interesting additions in KB5101684 is Voice Isolation support for Windows Voice Access.
Microsoft is using advanced audio processing techniques to improve speech recognition by filtering:
Background conversations
Keyboard sounds
Environmental noise
Other unwanted audio sources
Users now receive three voice recognition modes:
Voice Isolation
Filters other speakers and background noise.
Remove Background Noise Only
Removes non-speech sounds like typing or door noises.
No Filtering
Uses standard microphone input without additional processing.
This feature is especially valuable for:
Remote workers
Accessibility users
Professionals using voice commands
Users in noisy environments
Microsoft is also expanding Voice Access language support with Korean language availability.
Windows Hello Enhanced Sign-in Security Expands Beyond Laptops
Security authentication receives an important upgrade through Windows Hello Enhanced Sign-in Security (ESS).
Previously, ESS was mostly limited to devices with built-in fingerprint sensors.
KB5101684 expands support to compatible external fingerprint readers.
This means:
Desktop users can use stronger biometric authentication.
Organizations can deploy secure fingerprint authentication more broadly.
Copilot+ PCs and enterprise systems gain additional protection.
Users can configure supported devices through:
Settings → Accounts → Sign-in Options
Microsoft’s goal is clear: move Windows authentication away from traditional passwords and toward hardware-backed security.
Secure Boot Protection Continues Expanding
Microsoft is also improving Secure Boot certificate deployment.
The update includes additional device targeting information, allowing more supported systems to automatically receive new Secure Boot certificates.
This matters because Secure Boot protects computers against:
Bootkits
Firmware malware
Unauthorized operating system loaders
As attackers increasingly target firmware-level components, maintaining updated Secure Boot infrastructure becomes critical.
Enterprise Improvements: Better MDM and Office Reliability
KB5101684 addresses several enterprise-focused issues.
Mobile Device Management Fix
Previously, newly provisioned or recovered Windows devices could remain incorrectly marked as noncompliant after enrollment in services such as Microsoft Intune.
This caused:
Loss of corporate resource access
Compliance failures
Administrative confusion
The update resolves this issue.
Office Virtualization Improvements
Microsoft also improved Office application stability in virtualized environments.
Users should experience fewer problems when:
Opening Office applications.
Closing virtual sessions.

One important bug fix addresses Windows File History backups.
Some users experienced failed automatic backups when saving data to network shares using SMB.
Windows incorrectly reported:
“Invalid credentials”
even when authentication details were correct.
KB5101684 fixes this false error and improves backup reliability.
For businesses relying on network storage, this is a valuable improvement.
Windows Search Gets Better at Understanding Users
Windows Search is receiving smarter behavior.
The update improves application discovery by handling:
Typographical mistakes.
Partial application names.
Incorrect spelling.
For example, users searching for a partially remembered application name should have a higher chance of finding the correct program.
Microsoft is also improving Settings search relevance, helping users locate configuration options faster.
Touchpad Controls Become More Customizable
