Microsoft has released the Windows 11 KB5050094 Preview Update for devices running Windows 11 version 24H2. The optional cumulative update upgrades eligible PCs to OS Build 26100.3037 and introduces a wide range of quality improvements, interface enhancements, and bug fixes that will eventually become part of the next Patch Tuesday security update.
Unlike security updates, KB5050094 focuses on refining the Windows 11 experience by improving File Explorer, taskbar animations, Windows Studio Effects, mobile hotspot functionality, and overall system stability. Microsoft has also fixed numerous issues affecting Task Manager, Windows Update installation, Remote Desktop Gateway, memory usage, domain joining, mouse behavior, and sleep recovery.
Because this is a Preview Update, installing it is optional. Users who prefer maximum stability can safely wait until these improvements arrive automatically in the following month’s cumulative security update. On the other hand, users who want to experience the latest Windows enhancements early can install the update manually through Windows Update.
In this guide, we’ll look at everything new in Windows 11 KB5050094, including its features, bug fixes, known issues, and whether you should install it.

KB5050094 is an optional non-security cumulative preview update for Windows 11 version 24H2. After installation, the operating system is upgraded to Build 26100.3037.
Preview updates allow Microsoft to test new features and quality improvements before rolling them out to every Windows 11 device during the next mandatory Patch Tuesday release. Since these updates aren’t security-related, users can skip them without affecting the security of their PC.

What’s New in Windows 11 KB5050094?
Microsoft has introduced several usability improvements throughout Windows 11. While some features are rolling out gradually, others become available immediately after installing the update.
Better Taskbar Preview Animations
One of the most noticeable visual improvements is the updated taskbar thumbnail previews.
When you move your mouse over an app icon on the taskbar, preview windows now appear with smoother animations and improved responsiveness. Although this is a relatively small change, it helps Windows 11 feel more polished during everyday multitasking.
Windows Studio Effects Indicator
Users with supported AI-enabled cameras now receive a new system tray indicator whenever an application is actively using Windows Studio Effects.
The icon allows users to quickly identify when camera enhancements such as Background Blur, Eye Contact, Portrait Light, or Automatic Framing are active. Selecting the icon also opens the Studio Effects page directly in Quick Settings for easier management.
File Explorer Improvements
Microsoft continues refining File Explorer with several welcome enhancements.
Shared files can now be accessed more easily through Home, making collaboration more convenient for Microsoft account users.
Additionally, when users right-click folders in the left navigation pane, the New Folder option now appears directly in the context menu, eliminating extra clicks while organizing files.
Networking and Settings Improvements
KB5050094 also introduces useful networking enhancements.
6 GHz Mobile Hotspot Support
Windows 11 Mobile Hotspot now supports 6 GHz wireless connections on compatible hardware.
Users with Wi-Fi 6E devices can enjoy faster wireless sharing speeds and reduced network congestion while using their PC as a hotspot.
Time Zone Changes Without Administrator Rights
Microsoft has simplified time zone management.
Standard users can now change their device’s time zone directly from the Settings app without requiring administrator privileges, making the feature especially useful for business laptops and shared computers.
Major Bug Fixes Included in KB5050094
Microsoft has resolved a large number of bugs across Windows 11.
Task Manager Performance
Closing Task Manager now happens much faster than before. Previous versions could remain open for several seconds after clicking the close button.
Windows Update Installation
A problem preventing some cumulative updates from installing has been resolved.
Previously, affected systems displayed Error 0x800736b3 after a Feature on Demand installation failed. Microsoft has corrected this issue in KB5050094.
Domain Join Issues
Some enterprise devices occasionally failed to join Active Directory domains.
This issue has now been fixed, improving reliability for business and education deployments.
Sleep Recovery Improvements
Microsoft fixed a watchdog timeout problem involving Dam.sys that could occur after a computer resumed from sleep mode.
The change improves stability for devices frequently entering sleep or hibernation.
Memory Leak Fix
A memory leak affecting predictive text suggestions has been corrected.
Over time, this bug could gradually increase memory consumption while typing in supported applications.
Remote Desktop Gateway
Administrators using Remote Desktop Gateway with device redirection policies previously encountered authentication errors.
Microsoft has resolved these connection issues in KB5050094.
Security and Reliability Improvements
Although KB5050094 is not a security update, it still contains important security-related enhancements.
Microsoft has updated the Windows Kernel Vulnerable Driver Blocklist, expanding protection against Bring Your Own Vulnerable Driver (BYOVD) attacks. These attacks attempt to exploit legitimate but vulnerable drivers to gain elevated system privileges.
Keeping the driver blocklist current helps improve Windows Defender’s ability to prevent known vulnerable drivers from loading.
The update also includes the latest Servicing Stack Update (KB5050108), ensuring future Windows updates install more reliably.
Known Issues in KB5050094
Despite the long list of improvements, Microsoft acknowledges several known issues.
Remote Desktop Freezing
After installing KB5050094, some users may experience Remote Desktop sessions freezing shortly after connecting.
When this occurs, keyboard and mouse input stop responding until the session is disconnected and reconnected.
Microsoft later observed increased reports of Remote Desktop disconnections following later cumulative updates based on this preview release and documented the issue in the Windows release health information.
Roblox on ARM Devices
Players using ARM-based Windows PCs cannot currently install or launch Roblox from the Microsoft Store.
Microsoft states that Roblox is working on a permanent solution.

Conclusion
Windows 11 KB5050094 is a substantial preview update that focuses on improving everyday usability rather than introducing major new features. From smoother taskbar animations and File Explorer enhancements to networking upgrades and dozens of stability fixes, the update refines many areas of Windows 11 version 24H2.
The inclusion of improved Windows Studio Effects integration, better Mobile Hotspot support, and expanded driver security protections makes the update worthwhile for enthusiasts who like trying the latest Windows improvements. However, because it is an optional preview release—and because Microsoft has acknowledged issues affecting Remote Desktop—business users and anyone who prioritizes maximum stability may prefer to wait until these changes are delivered as part of the next mandatory Patch Tuesday update.
Overall, KB5050094 represents another incremental step toward making Windows 11 24H2 more reliable, polished, and efficient for everyday users.
