June’s Windows 11 update KB5094126 is responsible for a blue screen and multiple other issues.

The June 2026 update of Windows 11 by Microsoft is causing issues for some users despite its promised enhancements and security fixes.

Earlier last week, the Net Workshop announced updates focusing on enhancing the speed of the Start menu, system search, and introducing new shared audio features. However, shortly after the release, users started reporting bugs on forums, social media, and specialized websites.

What issues are associated with the KB5094126 update?

The most critical issues typically occur shortly after the update is installed, based on the reports analyzed thus far.

Some HP computers may encounter issues with Windows 11 startup, leading to a blue screen error. Alternatively, the system might prompt for a BitLocker recovery key to access the computer.

There are also reports of issues with File Explorer, where users have reported problems with OneDrive syncing and the service folder in the Windows sidebar displaying as empty or behaving unstably.

Companies are experiencing challenges following the software update, particularly with enterprise applications and managed environments that are not functioning correctly, especially on systems with stringent security measures and BitLocker integration.

Among the issues that have been reported to date are:

• BSOD occurs following update installation.
• Entry into BitLocker recovery mode occurred unexpectedly.
• Some HP laptops are experiencing issues with boot failures.
• OneDrive synchronization issues in File Explorer.
• Enterprise applications not functioning properly.
• Facilities experiencing malfunctions or errors while updating.

Has Microsoft acknowledged the identified issues?

Microsoft has not yet addressed these concerns on the official Windows 11 “known issues” page or initiated a public inquiry into the reports.

The company may be reviewing telemetry data before making an official statement in response to complaints that surfaced shortly after Patch Tuesday was released.

The KB5094126 update is essential as it addresses crucial security flaws, so it is advisable not to uninstall it right away unless the computer is experiencing severe issues that disrupt regular operations.

What should you do if your computer has been impacted?

If you encounter issues after installing the update, there are basic steps that can be taken to address them. Although Microsoft has not acknowledged these problems and no immediate fix is available, a temporary solution is to store the BitLocker recovery key in your Microsoft account to prevent potential issues.

Backup important files before proceeding and check for new updates or drivers on Windows Update. If the system fails to boot, attempt to access the Windows Recovery Environment.

Consider removing the KB5094126 update via recovery mode if you notice any issues right after installation.

Corporate users should refrain from uninstalling the update until they receive guidance from the IT team, as removing it can impact security and compliance protocols.

Any updates on the KB5094126 update?

A notable development from Patch Tuesday June is the Low Latency Profile feature, designed to enhance the agility of Windows 11 during certain activities by temporarily boosting processor response to reduce issues like crashes and delays when opening applications or accessing system areas like the Start menu and Action Center.

This will be most noticeable on computers that were starting to slow down a bit in their daily use. It won’t give the computer a new processor, but it can improve how the system performs when launching programs, switching windows, or navigating menus.

The camera is now able to function in multiple applications simultaneously.

The Multi-App Camera in Windows allows users to use the webcam with multiple apps simultaneously, providing more flexibility for tasks like meetings, recording, and transmissions.

Windows 11 now permits multiple applications to use the camera at the same time, which can be beneficial for various activities like live streaming, online classes, virtual meetings, and utilizing accessibility tools.

Microsoft included a simple camera mode for situations where the webcam has issues, aiming to simplify camera operation and address stability issues on certain devices.

Now you have distributed the audio.

The update introduces Shared Audio, enabling simultaneous sound playback on two devices. This feature is handy for scenarios like two individuals watching a video on a laptop with separate headphones.

Many individuals have attempted to divide audio on Windows using adapters, manual settings, or third-party apps, but now there is a proposal to simplify this process within the system.

Availability of the novelty may differ based on the computer’s hardware and audio drivers, so not everyone will experience it in the same way initially.

File Explorer search is enhanced.

The Archives Explorer has been improved to display search results more quickly with fewer characters typed, making it easier to find documents, images, videos, and folders.

Users of Windows who deal with numerous files are aware that Explorer’s search function can be slow and imprecise. Microsoft is making progress in this area, with the June update offering some improvements.

The company continues to work on improving the Explorer by making adjustments related to long file names and search behavior, aiming to make it less restrictive and more dependable.

Task Manager displays improved utilization of the NPU.

Microsoft has started focusing more on NPUs, chips dedicated to artificial intelligence tasks, on newer computers with AI-powered PCs becoming more prevalent. The Task Manager on June Patch Tuesday now offers improved visibility of this component’s usage.

For individuals using a standard PC without an NPU, there won’t be significant changes. However, this update is crucial for more recent laptops, particularly the Copilot+ models. Users can now identify when AI functions are utilizing the specialized chip instead of depending only on the processor or video card.

This information provides greater transparency for Windows users interested in performance, battery life, and hardware usage.

Microsoft also transitioned to Secure Boot.

The June update introduces significant modifications to Secure Boot, a security function that safeguards the computer’s boot process, in addition to the visible news.

Microsoft is getting ready to update Secure Boot certificates due to the expiration of some certificates used on Windows devices starting in June 2026. The company stated that PCs without the new certificates will still operate normally, with the update being rolled out gradually through Windows Update.

Fix for virtualization and gaming error.

The KB5094126 update addresses an issue that could lead to error screens on certain computers following the installation of the optional update KB5089573. The issue was connected to scenarios involving system restarts, virtual machines, and specific games.

Microsoft has mentioned errors like HYPERVISOR_ERROR and KMODE_EXCEPTION_NOT_HANDLED, which can be alarming for users when they appear on blue screens or lead to more severe system freezes.

The company states that this issue has been fixed with the June update. It might be crucial for those who experienced problems after the optional May update to install Patch Tuesday.

In certain situations, custom folders may experience icon disappearances.

Microsoft has made a security update regarding how Windows handles desktop files.

Some users might observe that personalized icons or folder names specific to a location do not display accurately in downloaded content from the web or remote sources. The company clarifies that access to the folders remains unaffected, meaning the files are still present; the issue is only visual.

AI elements have been recently revised.

Microsoft has made enhancements to the internal components of Windows 11, such as features related to image search, content extraction, semantic analysis, and configuration model.

These modifications are aimed at getting the system ready for more intelligent features, particularly on computers that can work with local AI capabilities. Users may not always notice this type of update right away, but it is part of Microsoft’s plan to transform Windows 11 into a more unified platform with AI technology.

Installing KB5094126 explained

To set up the June 2026 Patch Tuesday, simply follow this route:

Settings > Windows Update > Advanced Options > Optional updates

The package should be displayed as KB5094126 Cumulative Update for Windows 11, version 2026-06.

After the installation process, you must reboot the computer to finish the update.
