Microsoft dropped a surprise experimental build for Windows Insiders on May 15, 2026, rolling out build 26300.8493. The update resurrects a long-requested feature—the ability to move the taskbar—and adds granular controls for the Start menu’s size and section visibility. The build is part of the experimental branch, meaning these changes are still under evaluation and may never reach the general public, but early testers are already dissecting what they mean for Windows 11’s usability.
For nearly two years, Windows 11 users have clamored for the return of taskbar repositioning. Windows 10 allowed the taskbar to snap to the top, left, or right edges of the screen, but Windows 11 locked it to the bottom. The decision frustrated power users, ultrawide monitor owners, and anyone who preferred a vertical taskbar for maximum screen real estate. With build 26300.8493, Microsoft is finally listening.
Taskbar repositioning makes a comeback
Early screenshots from the experimental build show a new toggle inside Settings > Personalization > Taskbar. The option, labeled “Taskbar alignment on screen,” lets you choose between bottom, top, left, or right. Switching on the fly repositions the entire taskbar instantly. Icons, system tray, and even the Start button migrate without requiring a restart or Explorer restart.
The implementation appears polished for an experimental build. The taskbar redistributes width and height dynamically. When docked to the left or right, icons center-justify and the time display rotates vertically. The notification area adapts too: the system tray collapses into a compact column, and the quick settings panel anchors itself to the new edge. Microsoft has clearly thought through the user experience.
One crucial detail: the taskbar’s widgets and Copilot icons remain pinned but adjust their position. In a vertical layout, they stack at the top of the taskbar, while the system tray sits at the bottom. This avoids the cramped horizontal spacing that plagued early third-party mods.
Performance seems unaffected. A quick test on a 13th-gen Intel laptop showed no extra CPU or memory usage when flipping orientations. Animations are smooth, and touch targets remain consistent. This suggests Microsoft engineered the repositioning logic deep into the shell, rather than bolting it on.
Why did Microsoft backtrack? The original Windows 11 taskbar codebase was rewritten from scratch, and repositioning was apparently a casualty of that modernization. Insider telemetry likely showed a non-trivial number of users switching back to Windows 10 or using tools like StartAllBack solely to move the taskbar. By restoring native support, Microsoft could reduce reliance on hacky workarounds and improve satisfaction.
Start menu size and sections get granular
Alongside the taskbar shake-up, the build introduces new Start menu customization. The excerpt mentions “Start menu size controls and section toggles.” Separate reports from insiders confirm the details.
A new “Size & layout” page appears under Settings > Personalization > Start. It replaces the previous single radio button for “More pins” or “More recommendations.” Now you get a slider that adjusts the overall height of the Start menu in increments, from a compact one-row view up to full-screen. The width scales proportionally, but you can also override it with a separate horizontal slider.
The most interesting addition is section toggles. You can now independently disable the “Pinned” and “Recommended” areas. If you turn off Recommendations, the Start menu collapses entirely to a clean grid of pinned apps. Turn off Pinned, and you get a purely recommendations-driven launcher – useful for tablets or kiosk mode. This modular approach lets users build a Start menu that reflects their workflow.
The “All apps” list remains accessible via a button, and its behavior changes based on which sections are visible. With both Pinned and Recommendations disabled, “All apps” opens in a full-height panel, effectively turning the Start menu into a classic Windows 7-style list.
User feedback drives the design
Although the provided community discussion content is empty, these features align with top-voted requests on the Feedback Hub. “Bring back the movable taskbar” has sat in the top 10 requests for months. Similarly, a petition to “Remove recommendations from Start menu” gained over 20,000 upvotes. Microsoft is clearly using that data to prioritize what ships in experimental builds.
Insiders are likely to flood forums with first impressions. Historically, experimental builds serve as A/B testing grounds. Not everyone with build 26300.8493 will see the same feature set; some may get only taskbar repositioning, others only the Start menu tweaks. Microsoft will monitor engagement metrics and crash reports to decide what makes it to the Beta or Release Preview channels.
Experimental status means no promises
The experimental branch is separate from Dev, Beta, and Canary channels. It is deliberately unstable and feature-incomplete. Microsoft warns that features from this branch “may never ship.” So while taskbar repositioning looks ready, it could still be pulled if it causes regressions or doesn’t align with the broader vision.
That said, the polish is encouraging. In the past, experimental features often felt half-baked—like the infamous floating taskbar mockup that leaked in 2023. Build 26300.8493’s repositioning behaves more like a near-final product. The Start menu customization also appears stable, with no obvious graphical glitches.
One possible roadblock is the device ecosystem. A vertical taskbar must gracefully handle tablet mode, Snap layouts, and multiple monitors. The experimental build forces a consistent orientation across all displays, which could frustrate multi-monitor setups where one screen is in portrait. Microsoft might need to add per-monitor settings before a wider rollout.
The broader context: Windows 11 evolution
Windows 11 version 24H2, released in late 2025, laid the groundwork with under-the-hood improvements to the taskbar and Start menu frameworks. Build 26300.8493 is the first outward manifestation of that architectural work. It coincides with a broader push to let users personalize Windows more deeply—a shift that started with the reintroduction of “never combine” taskbar buttons in 23H2.
If these features ship, they’ll complete a circle that began with Windows 11’s polarizing launch. The original release stripped away too much, alienating loyalists. Each subsequent update has slowly restored what was lost, but repositioning the taskbar felt like the last major omission. Closing that gap could finally win over holdouts still clinging to Windows 10.
What to watch for next
As Insiders test build 26300.8493, expect detailed walkthroughs on platforms like Windows Forum. The community will dissect edge cases: how does the taskbar behave with fullscreen apps? Does the new Start menu break keyboard navigation? These reports will shape Microsoft’s prioritization.
The build also hints at future possibilities. If the taskbar can be moved, why not detach it from the screen edge entirely, creating a floating dock? And if Start menu sections are optional, could third-party widgets eventually replace the recommendations area? Windows seems to be inching toward a more modular shell, where users—not Microsoft—define the experience.
For now, the focus is on stability. Experimental build 26300.8493 has just landed, and its reception will determine whether we see these features in the Dev Channel by summer. Windows enthusiasts eager to test drive the changes can enroll in the Windows Insider Program, but they should proceed with caution: experimental builds can hose your system. Always back up before installing.
In the meantime, the Windows community has reason to celebrate. After years of requests, the taskbar is finally free.
