Microsoft released a non-security preview update for Windows 11 on May 29, 2024, targeting fixes for File Explorer and the taskbar, two of the operating system’s most frequently used and most frequently frustrating components. The update, designated KB5037853, applies to OS Builds 22621.3672 and 22631.3672 and arrives as the latest in a string of cumulative patches that have steadily addressed interface stability problems over the spring of 2024. For the millions of people who rely on Windows 11 daily, the changelog reads like a repair list for issues that should not have persisted this long.
What KB5037853 Actually Fixes
The May 29 preview update carries fixes for Explorer.exe and taskbar-related problems that have dogged users for months. Among the known issues documented in the release notes is a crash involving Explorer.EXE and Taskbar.View.dll, a failure mode that can leave users staring at a blank desktop after waking their machine from sleep or restarting it. That specific crash has been a recurring complaint in Windows community forums, and its appearance in the KB5037853 documentation signals that Microsoft has at least acknowledged the scope of the problem.
The same update also includes a series of smaller reliability tweaks that collectively aim to reduce hangs, slowdowns, and interface glitches. File Explorer, which has been a focal point of complaints since Windows 11 launched, receives adjustments intended to smooth out navigation and reduce the odds that opening folders, searching for files, or interacting with network locations will trigger a freeze. On the taskbar side, KB5037853 addresses conditions that could prevent icons from appearing promptly, interfere with system tray behavior, or cause the entire shell to restart unexpectedly.
Because this is a non-security preview update, it does not arrive automatically through Windows Update for most users. Preview cumulative updates require manual installation, which means the fixes will reach a broader audience only when they are folded into the next mandatory Patch Tuesday release. That distinction matters: the people most affected by taskbar crashes are often the least likely to seek out optional patches, so the real-world impact of these fixes will lag behind their availability by weeks.
A Pattern of Incremental Taskbar and Explorer Repairs
KB5037853 did not appear in isolation. Microsoft has been shipping taskbar and File Explorer fixes through its preview channel on a roughly monthly cadence since at least early 2024. The company’s April preview update, identified as KB5036980 and applying to OS Builds 22621.3527 and 22631.3527, bundled similar quality improvements for shell components, as detailed in Microsoft’s support notes. That update was also classified as a non-security preview, following the same optional-install model.
Before that, the March 12 Patch Tuesday cumulative update, KB5035853, brought Explorer-related tweaks to a wider audience through the mandatory update channel. That release, which targeted OS Builds 22621.3296 and 22631.3296, was distributed automatically to most Windows 11 systems and also offered manual deployment packages for organizations managing large fleets of devices. By passing through Patch Tuesday, those fixes reached far more users than either of the spring preview releases.
The timeline tells a clear story. Microsoft tests interface fixes in optional preview updates, gathers telemetry and bug reports, then promotes the validated changes into the next Patch Tuesday release. This preview-to-stable pipeline is not new, but its visibility has increased because the fixes themselves address such basic functionality. When the taskbar fails to load or File Explorer hangs during a search, users notice immediately. The frequency of these patches suggests the underlying codebase for Windows 11’s shell components has been less stable than Microsoft would prefer.
Why the Preview Channel Strategy Matters for Users
The distinction between preview and Patch Tuesday updates is more than a technical footnote. It shapes who gets fixes and when. Preview updates like KB5037853 and KB5036980 are designed for users and IT administrators willing to test changes before they reach the general population. Microsoft benefits from this arrangement because it gets real-world feedback without risking a broken patch on every Windows 11 machine simultaneously. Users who opt in get early access to bug fixes but also accept the risk that the preview itself might introduce new problems.
For most people, the practical advice is straightforward: if taskbar crashes or File Explorer instability are disrupting daily work, manually installing the May 29 preview update is worth considering. If those issues are not present, waiting for the next Patch Tuesday release is the safer path. The March 2024 cumulative update demonstrated that preview-tested fixes do eventually land in the mandatory channel, so patience is a reasonable strategy for users who prefer stability over speed.
That said, the gap between preview availability and general rollout creates a window where known fixes exist but most affected users do not have them. Microsoft does not publish specific timelines for when preview fixes will graduate to Patch Tuesday, which leaves users guessing. This ambiguity is a recurring frustration in the Windows update ecosystem, and it has not improved meaningfully over the past year. For administrators responsible for hundreds or thousands of PCs, that uncertainty complicates planning: they must weigh the benefit of faster relief from bugs against the risk that an untested preview could destabilize critical systems.
The Bigger Question Behind Small Fixes
Most coverage of Windows updates treats each patch as an isolated event, a list of fixes to scan and forget. But the spring 2024 sequence of taskbar and File Explorer updates raises a harder question: why are these core interface components still producing crashes and hangs nearly three years after Windows 11 launched?
Part of the answer lies in the architectural changes Microsoft made when it redesigned the taskbar for Windows 11. The new taskbar was built on a different rendering framework than its Windows 10 predecessor, and that shift introduced new failure points. The Taskbar.View.dll crash referenced in KB5037853 is a symptom of that transition. Microsoft has been patching these failure points iteratively rather than shipping a single large overhaul, which keeps each individual update small but extends the timeline for full stability.
Another factor is the sheer diversity of hardware and software configurations running Windows 11. A fix that stabilizes Explorer.exe on one set of graphics drivers, storage controllers, and third-party shell extensions might expose a new edge case on another. Preview updates help Microsoft surface those conflicts before a fix is pushed to the entire installed base, but they also highlight how fragile the modern Windows shell can be when stretched across so many different environments.
There is also a perception problem. When users see repeated references to Explorer and taskbar fixes in update notes month after month, they reasonably wonder whether the platform is fundamentally unreliable. Even if each patch addresses a narrow corner case, the cumulative effect can feel like a never-ending repair job on the same parts of the operating system. That perception is especially damaging for Windows 11, which Microsoft has positioned as a more polished, design-forward evolution of Windows 10.
What This Means for Everyday Windows 11 Users
For individual users, the immediate takeaway is practical rather than philosophical. If you have experienced blank desktops after waking from sleep, missing taskbar icons, or Explorer windows that stop responding, KB5037853 is directly relevant. Installing the preview update may not cure every quirk, but it targets precisely the kinds of failures that disrupt basic workflows like launching apps, switching windows, or browsing files.
Those who manage family PCs or small offices should consider a more deliberate approach. One strategy is to designate a single machine as the “canary” that receives preview updates first. If KB5037853 and similar releases behave well there for a week or two, you can be more confident rolling them out to other systems manually. For everyone else, letting Windows Update deliver only the standard Patch Tuesday cumulative updates remains the lowest-risk option, with the understanding that fixes for annoying but non-critical bugs will arrive more slowly.
In the long run, the hope is that this burst of shell-related patches represents the tail end of Windows 11’s growing pains rather than a permanent maintenance pattern. The fact that Microsoft is now explicitly calling out Explorer.exe and taskbar reliability issues in its own support notes suggests the company recognizes how central these components are to user trust. Whether the May 29 preview update finally quiets the most visible complaints, or simply marks another step in a longer journey toward stability, will become clear only as more users install it, either now, by seeking it out, or later, when its fixes are quietly folded into the next mandatory cumulative release.
