Windows 11 finally lets users move the taskbar to any edge of the screen. Microsoft is rolling out Experimental Preview Build 26300.8493 to Windows Insiders on May 15, 2026, restoring a feature that many power users have demanded since the operating system launched. The build officially adds the ability to pin the taskbar to the top, left, right, or bottom of the display—a capability that was standard in Windows 10 but stripped away in the original Windows 11 release.

This change arrives nearly five years after Windows 11 first shipped with a permanently bottom-docked taskbar. Users who have been relying on registry hacks or third-party utilities to regain side-mounted taskbars can now do so natively within the Settings app. The preview is currently limited to the Dev and Canary channels, but it signals a major shift in Microsoft's approach to taskbar customization.

The long road to a movable taskbar

When Windows 11 debuted in October 2021, the centered Start menu and taskbar icons were headline features. But the decision to lock the taskbar to the bottom of the screen stunned many longtime Windows users. Vertical taskbars—especially left-aligned ones—have been a staple for ultrawide monitor owners and anyone who prefers maximizing vertical screen real estate. Microsoft's explanation at the time pointed to a ground-up rewrite of the taskbar codebase, which initially sacrificed flexibility for modern aesthetics and new functionality like widgets.

Community backlash was immediate. Feedback Hub posts amassed thousands of upvotes, and third-party tools such as StartAllBack and ExplorerPatcher surged in popularity. These utilities effectively restored the classic taskbar behavior, but they often introduced instability or broke with system updates. Some users even discovered hidden registry keys that could unlock top or side positions, but the experience was glitchy—animations stuttered, system tray icons overlapped, and notification flyouts appeared in the wrong place.

Microsoft acknowledged the demand. In a 2022 AMA, the Windows engineering team stated that while they were aware of the requests, re-architecting the taskbar for movement was “not a simple thing.” Over the following years, incremental improvements focused on other taskbar features: drag-and-drop, never-combine labels, and an updated system tray. The movable taskbar remained conspicuously absent—until now.

What’s new in Build 26300.8493

Build 26300.8493 is labeled as an “Experimental Preview,” meaning the feature might evolve before reaching general availability. Insiders who install the build can head to Settings > Personalization > Taskbar > Taskbar behaviors. A new Taskbar location on screen dropdown offers four choices:

  • Bottom (default)
  • Top
  • Left
  • Right

Changing the position takes effect immediately. The Start menu, search flyout, task view, and notification center all reorient accordingly. When moved to the top, the taskbar anchors to the screen’s upper edge, with icons and widgets aligning correctly. Left and right placements stack icons vertically, using a slimmer profile that conserves horizontal space—ideal for portrait-oriented monitors or setups where width is at a premium.

Microsoft has redesigned the system tray and clock area to adapt to each orientation. On a left-aligned taskbar, the clock, network, volume, and battery indicators rotate to a vertical stack, much like they did in Windows 10. The notification badge and “Show hidden icons” caret reposition gracefully. Animations for opening the Start menu or Quick Settings now flow in the appropriate direction based on the taskbar’s location.

How the community is reacting

Early feedback from Insiders has been largely positive, though not without caveats. On the Windows Forum, several users reported that moving the taskbar to the left or right can cause minor alignment issues with third-party app icons. “Some tray icons don't scale perfectly,” noted one tester. “But after a restart, most of them settled down.” Another praised the return of vertical taskbars for her 34-inch ultrawide monitor: “I finally have my vertical space back. No more wasted horizontal bar at the bottom.”

Power users who had grown accustomed to StartAllBack are now uninstalling the tool. “I've been using ExplorerPatcher for years just for the left taskbar,” a forum member wrote. “Happy to see it natively supported again. Slightly less snappy than the third-party hacks, but at least I don't have to worry about updates breaking it.”

One recurring comment highlights that the new implementation still lacks some customization found in Windows 10. For instance, users cannot independently resize the taskbar when it’s on the left or right—the width appears fixed. Additionally, the “Combine taskbar buttons” option works, but the never-combine labels mode doesn't truncate elegantly on vertical bars yet. Microsoft is expected to refine these details based on Insider telemetry.

The technical overhaul behind the scenes

Getting the taskbar to move required a fundamental rework of its layout engine. In earlier Windows 11 builds, the taskbar relied on a new XAML-based modern framework, but that code assumed a static bottom position. To enable relocation, Microsoft engineers had to reintroduce coordinate transforms and adaptive layout logic reminiscent of the legacy Windows 10 shell. According to a Microsoft developer's comment on a GitHub thread, “The shell infrastructure now supports dynamic placement of the taskbar ‘window,’ but we're still ironing out the quirks with floating flyouts and input hit-testing.”

This explains why the feature took so long. The taskbar must not only draw itself at any edge but also correctly manage all the pop-ups that attach to it: thumbnails, jump lists, notification toasts, and the Action Center. Each of these elements has to compute its position relative to a variable taskbar edge. For vertical orientations, the system tray and clock also need to flow from top to bottom rather than left to right—a non-trivial change that touches accessibility settings and DPI scaling.

Build 26300.8493 is thought to be based on an internal branch that has been in development for at least 18 months. The build number—jumping from the 26100 series—suggests a forward-integration with future Windows 11 releases, possibly the 25H2 or 26H1 update. Experimental builds often serve as proving grounds for features that land in the next major feature update.

How to try it today

Windows Insiders enrolled in the Dev or Canary channel can check for updates through Settings > Windows Update. Once Build 26300.8493 downloads and installs, the new taskbar location option appears automatically. No registry hacks or vivetool commands are required.

For those not in the Insider program, it’s possible to enroll a secondary machine or a virtual environment. However, Experimental Preview builds can be unstable, so Microsoft warns against installing them on primary production devices. The build also includes other changes, such as an updated battery icon with percentage display and a revamped emoji picker, but the movable taskbar is the headline act.

If something goes wrong—like taskbar icons disappearing or the taskbar failing to render—a quick workaround is to switch the location back to bottom and restart Windows Explorer. Most early bugs have been tied to graphics drivers, so keeping GPU drivers updated is advisable.

What this means for the future of Windows 11

The movable taskbar’s arrival is a strong indicator that Microsoft is listening to its enthusiast base. Windows 11 has been steering toward a more opinionated design language, but this move shows a willingness to reintroduce classic power-user features when user demand is persistent enough. It also aligns with broader trends: ultrawide and multi-monitor setups are increasingly common, and vertical screen real estate is more valuable than ever for productivity.

Retail release timing remains speculative. If the feature passes muster in the Dev and Canary channels without major regressions, it could graduate to the Beta channel in a month or two and then ship to the general public with the next feature update. That update—possibly Windows 11 25H2—might arrive in the second half of 2026, though Microsoft hasn't confirmed any schedule.

Competitors like macOS and several Linux desktop environments have offered movable panels for decades, making Windows the latecomer. Still, for the 400 million-plus Windows 11 users, this is a welcome return to form. The days of a rigidly bottom-locked taskbar appear to be numbered.

A boost for multitaskers and accessibility

Beyond the aesthetic preference, a movable taskbar offers tangible usability benefits. Freelancers who work with long code files or documents often prefer a left-side taskbar to maximize vertical lines of text. Designers with color-critical workflows appreciate a top-mounted taskbar that doesn't interfere with the color calibration of the lower screen edge. And users with motor impairments may find a side taskbar easier to reach with minimal mouse travel.

Microsoft has not yet highlighted accessibility enhancements in this build, but Insiders have noticed that the keyboard shortcuts for navigating the taskbar (Win + T, Win + B) adjust to the new orientation. Narrator also announces the taskbar's current position, which improves screen-reader support.

Potential downsides and edge cases

No preview build is perfect, and Build 26300.8493 has its share of rough edges. Some users report that the taskbar’s right-click context menu occasionally opens on the opposite edge of the screen after a relocation. Widgets can overlap the notification area when the taskbar is on the left. And the new Copilot button—if enabled—does not reposition elegantly in vertical layouts.

Gaming mode also interacts oddly with a top-mounted taskbar: some full-screen games conflict with the auto-hide behavior, causing the taskbar to flicker during loading screens. Microsoft is actively collecting feedback via the Feedback Hub and has already issued a small cumulative update to address the most critical rendering issues.

For those who rely on multiple monitors, the movable taskbar currently applies the same position to all displays. There is no option yet to have a left taskbar on monitor one and a bottom taskbar on monitor two—a feature that Windows 10 supported. Insiders have filed feature requests for per-monitor taskbar positioning, and Microsoft hasn't ruled it out for future builds.

Looking ahead

The restoration of the movable taskbar is more than a nostalgic nod to Windows 10. It represents a maturing Windows 11 that no longer forces users into a one-size-fits-all interface. As Microsoft continues to evolve the desktop, the balance between modern design and functional flexibility will define the platform's success.

With Build 26300.8493, Windows Insiders get a meaningful preview of that future. The path to general availability still holds hurdles, but for the first time since late 2021, Windows 11 users can officially decide where their taskbar belongs—top, bottom, left, or right.
