Introduction: Small Design Tweaks, Big User Impact
The file manager is one of the most frequently used components of any operating system, yet in Windows 11, File Explorer has often been criticized for inconsistent design and performance hiccups. While Microsoft has gradually improved the experience through updates, several issues still frustrate users, especially those who rely on File Explorer daily for work and organization.
Now, new preview builds suggest that Microsoft may be preparing a minor but noticeable design refresh. The company appears to be experimenting with rounded corners for the address bar and search field, aligning the interface more closely with other Windows 11 apps like the Settings panel. At the same time, Microsoft has finally acknowledged and started fixing a long-standing bug that causes a white flash when opening File Explorer in dark mode, particularly when the default view is set to “This PC.”
These updates may seem small at first glance, but they reflect Microsoft’s ongoing effort to refine the visual consistency and reliability of Windows 11.
File Explorer May Soon Feature Rounded Address and Search Bars
One of the most noticeable potential design updates involves rounded corners for the address bar and search bar inside File Explorer. This adjustment mirrors the aesthetic already used in other Windows 11 applications, especially the Settings app.
The feature was spotted in preview builds by a Windows enthusiast known online as Phantomofearth. Although the rounded interface elements have been present for some time in test builds, they remained hidden because the feature is disabled by default.
Because of this, most users never noticed the change during testing. Microsoft has not yet confirmed exactly when or if this visual tweak will roll out to all users. However, the discovery suggests that the company is working toward greater design consistency across Windows 11.
Windows 11 File Explorer Still Faces Performance and Design Challenges
Despite its importance, File Explorer in Windows 11 has faced significant criticism since the operating system launched. Users frequently report that certain sections load slower than expected, especially when browsing large folders or opening new windows.
The performance concerns have become serious enough that Microsoft has implemented background preloading of File Explorer, attempting to speed up the initial launch by loading parts of the program before users open it.
Beyond performance, design inconsistencies remain a major issue. For example, users sometimes encounter light-themed pop-ups while the system is set to dark mode, which disrupts the visual experience. In addition, not every interface element respects Windows 11’s signature rounded design language.
These inconsistencies highlight the challenges Microsoft faces while modernizing legacy components that were originally designed for much older versions of Windows.
Microsoft Finally Addresses the White Flash Bug
Another long-standing annoyance involves a white flash that appears when opening File Explorer while using dark mode.
The issue became more noticeable after Microsoft introduced a major change in November 2025, when it released dark mode support for file operation dialogs. This update included dialogs for tasks like copying, deleting, or moving files, and it arrived as part of the Windows 11 update KB5070311.
While the update improved dark mode support overall, it also accidentally disrupted the existing dark theme implementation in File Explorer.
As a result, users began seeing brief white flashes when opening folders or navigating between sections.
The Bug Mostly Disappeared, Except for “This PC”
Microsoft eventually released a cumulative update that addressed many of the white flash issues affecting File Explorer.
However, one area remained problematic: the “This PC” view.
Users who configured File Explorer to open directly to “This PC” instead of the default Home tab continued to experience white flashes when launching the application.
The bug persisted for approximately five months, frustrating users who rely on this view to access drives and system storage quickly.
For a long time, Microsoft remained silent about the issue, leaving users unsure whether the company even recognized the problem.
Microsoft Confirms the Issue and Promises a Fix
In a recent Insider Program update, Microsoft finally acknowledged the bug.
Within the release notes for Windows 11 Build 26220.7961, the company confirmed that it had identified the problem and implemented a fix.
According to Microsoft, the update removes the white flash that appears when launching File Explorer windows or tabs when the default opening location is set to “This PC.”
The company also addressed another visual glitch where white flashes occurred while resizing File Explorer elements.
For now, these fixes are available only to beta testers in the Windows Insider program, but they are expected to reach the general public once testing is complete.
Additional Changes Coming to Windows 11
File Explorer improvements are only one part of Microsoft’s broader plan to refine Windows 11.
The company is also experimenting with improvements to the Quick Settings panel, where users can adjust system features like Wi-Fi, Bluetooth, and brightness.
Future updates may allow users to change themes directly from Quick Settings, making personalization faster and more convenient.
Another small but helpful change will allow users to unpin items from Quick Settings, giving them more control over the layout of frequently used toggles.
These adjustments may appear minor, but they demonstrate Microsoft’s attempt to make Windows 11 feel more polished and user-friendly.
What Undercode Say:
Microsoft Is Quietly Fixing Windows 11’s Most Visible Frustrations
While the changes described may look cosmetic on the surface, they reveal a deeper story about the evolution of Windows 11. The operating system launched with a bold visual redesign, but many legacy components were not fully aligned with the new design philosophy.
File Explorer is one of the clearest examples of this struggle.
The application originated decades ago and has been gradually modernized over multiple Windows versions. Integrating modern UI elements like rounded corners, smooth animations, and consistent dark mode behavior into such an old framework is technically complex.
The presence of mismatched UI elements, white flashes, and inconsistent design shows how difficult this transition has been.
However, Microsoft’s recent fixes suggest the company is prioritizing refinement rather than radical redesign.
Instead of replacing File Explorer entirely, Microsoft appears to be slowly improving it piece by piece. Rounded address bars, improved dark mode behavior, and background preloading are all part of this gradual strategy.
Another important aspect is the role of the Windows Insider Program. Many issues are discovered and resolved through feedback from testers before reaching the general public. The white flash bug, for example, remained unresolved for months before Microsoft officially acknowledged it in Insider release notes.
This process demonstrates both the strengths and weaknesses of Microsoft’s update pipeline.
On one hand, it allows the company to experiment with design changes and gather feedback before broad release. On the other hand, issues can remain unresolved for extended periods, which can frustrate everyday users.
The criticism surrounding Windows 11’s reputation is also significant. In recent years, Microsoft has faced increasing scrutiny regarding performance issues, inconsistent design, and feature fragmentation.
Improving File Explorer might not seem dramatic, but it targets a core daily workflow used by millions of users worldwide.
Even small improvements in responsiveness, visual consistency, and stability can significantly improve the overall perception of the operating system.
Another interesting angle is how design decisions affect user trust.
When dark mode suddenly shows bright white flashes, it creates the impression that the system is unfinished or poorly optimized. Fixing these small visual problems helps reinforce the sense that the platform is stable and thoughtfully designed.
Finally, Microsoft’s gradual UI updates hint at a larger trend in modern operating systems.
Instead of massive redesigns every few years, companies increasingly prefer continuous refinement through incremental updates. This approach allows the system to evolve steadily without forcing users to adapt to dramatic changes.
Windows 11’s File Explorer improvements fit perfectly into this philosophy.
