Microsoft has finally delivered one of the most requested Windows 11 customization features to Insiders: a native, officially supported Taskbar Size control. The new setting arrives on June 26, 2026, as part of Experimental Build 26300.8758, and gives testers a straightforward way to adjust the taskbar height directly through the Settings app.

Buried within the Settings > Personalization > Taskbar page, the dedicated control marks a significant shift in Microsoft’s approach to Windows 11 personalization. For the first time since the operating system’s 2021 debut, users no longer need to hunt down registry tweaks or rely on third-party tools to resize the taskbar—the capability is now a first-class citizen of the user interface.

A Frustrating Legacy of One-Size-Fits-All

Windows 11 launched with a radically redesigned taskbar that, while visually polished, stripped away many customization options that power users had come to rely on. Among the most glaring omissions was the ability to change the taskbar’s size. For decades, Windows allowed users to choose between small, medium, or large taskbar configurations, but Windows 11’s initial release locked everyone into a single height that many found excessively tall—or, conversely, too cramped when display scaling was applied.

The backlash was immediate and vocal. In the Feedback Hub and across community forums, thread after thread demanded the return of taskbar resizing. Some enthusiasts discovered that they could manually alter the taskbar’s size by editing the Registry key HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\TaskbarSi, but this was hardly a mainstream solution. Moreover, subsequent cumulative updates occasionally broke or reset these unsanctioned modifications, leaving users frustrated and reminding them that the workaround existed on borrowed time.

Enter Build 26300.8758: A Long Time Coming

The insider release on June 26 finally addresses that pain point. While Microsoft’s official changelog for build 26300.8758 remains sparse at the time of writing, the presence of a dedicated size option within the Settings app signals that the feature is undergoing formal testing before a broader rollout. It appears under a new Taskbar size subheading inside the Personalization section, though the exact labeling and available presets have not been publicly detailed in the initial announcement.

Given historical patterns and leaked earlier builds, the control likely offers a dropdown or a set of radio buttons with options such as Small, Medium, and Large. In legacy versions of Windows, these corresponded to taskbar heights of roughly 40, 48, and 56 pixels at standard 100% scaling, respectively. Whether Microsoft reintroduces those exact dimensions or refines them for modern high-PPI displays remains to be seen, but the ability to shrink the taskbar will be a welcome reprieve for users of laptops and small-screened devices where vertical real estate is at a premium.

How to Find the Setting

Insiders enrolled in the Dev or Canary channels who receive build 26300.8758 can locate the feature by following these steps:

  • Open Settings from the Start menu or by pressing Win + I.
  • Navigate to Personalization in the left pane.
  • Click on Taskbar.
  • Scroll to the Taskbar behaviors or Taskbar size section (the exact grouping may vary during the experimental phase).
  • Use the newly introduced control to toggle between the available size modes.

The change takes effect immediately, though a restart of the Explorer process—automatically handled by the system—may be required in some cases for the visual update to fully render.

Experimental Builds and What They Mean

Build 26300.8758 carries the “Experimental” tag, which signifies that Microsoft is testing this particular implementation with a limited subset of Insiders. This approach allows the company to gather feedback and telemetry on how users interact with the feature before committing it to the main development branch. Features in experimental builds can evolve rapidly or even be pulled entirely if they introduce unforeseen bugs or negatively impact system stability.

That said, the inclusion of a Settings-based toggle suggests that Microsoft is confident enough in the underlying code to expose it to a wider Insider audience. The taskbar size functionality has been spotted in various states of completion in previous insider builds, but always as a hidden enhancement requiring third-party tools like ViVeTool to activate. Its emergence as a visible, labeled option is a strong indicator that public release is on the roadmap.

Community and User Impact

With no curated discussion thread available at the time of reporting, the immediate reaction from the Insider community is still unfolding. However, early sentiment can be inferred from the long-standing demand for this feature. Windows 11 enthusiasts who have doggedly defended the operating system’s modernization efforts have often cited the lack of taskbar flexibility as a glaring blind spot. The arrival of the size control will likely quell a significant volume of feedback hub complaints and could even tempt holdouts still clinging to Windows 10 to reconsider upgrading.

For productivity users, the practical benefit is more than cosmetic. A smaller taskbar means extra vertical pixels for documents, code editors, or web content. In tablet mode or on 2-in-1 devices, a larger taskbar can improve touch targets. The ability to switch between these modes without editing the registry or rebooting into a different user profile is a measurable quality-of-life improvement.

The Broader Taskbar Renaissance

This update fits into a larger pattern of Microsoft gradually restoring and modernizing classic taskbar behaviors. Since the initial Windows 11 launch, the taskbar has gained back the ability to show ungrouped program labels, display seconds in the system tray clock, and—most recently—support for a revamped notification area that better handles app overflow. A size control was arguably the last major missing piece for many users who define their workflow around the taskbar’s layout.

The company has also been paying closer attention to accessibility and personalization in the post-24H2 era. Dedicated controls for font sizes, color contrast, and interface density are increasingly finding their way into the Settings app rather than being relegated to legacy Control Panel applets or hidden power-user tools. The Taskbar Size setting aligns with that philosophy.

A Note on Stability and Known Issues

Experimental builds are inherently less stable than production releases. Insiders installing 26300.8758 should be aware that other areas of the shell might behave unexpectedly. Microsoft’s release notes for this build likely include a list of known issues—as of this writing, those details have not been independently confirmed. Users who rely on their devices for critical daily work are advised to enroll in the Insider program on a secondary machine or virtual environment.

What Comes Next

If testing proceeds smoothly, the Taskbar Size control could ship to all Windows 11 users as part of an upcoming Moment update or the next major feature release. Based on the typical cadence, a broad rollout might land in late 2026 or early 2027. The feature could also make its way into Windows 11 Enterprise and Education editions, where IT administrators often standardize taskbar layouts via Group Policy—making a native setting far more manageable than registry tweaks.

In the meantime, Insiders are encouraged to submit feedback via the Windows Feedback Hub, specifically tagging it under Desktop Environment > Taskbar. Microsoft’s engineering team actively monitors these channels during the experimental phase, and user input can directly influence the final design, available sizes, and even additional customization options like icon spacing or clock font scaling.

Final Thoughts

For a platform that has spent five years redefining its identity, the return of a simple taskbar size selector is small news in the grand scheme. But it’s precisely these small touches that shape daily computing experiences. With build 26300.8758, Microsoft signals that it’s listening—and that even in an era of AI-driven interfaces and virtual desktops, the fundamentals of a comfortable, personalized workspace still matter.

Insiders eager to test the feature should check for updates and dive into the Settings app. The rest of the Windows user base can watch nervously and hope that this experimental control graduates quickly to the production channel.
