Microsoft’s latest Windows 11 Insider build, released in late July 2026, restores one of the most-requested features from power users—a movable taskbar—while also introducing public preview support for WSL containers and a long-awaited overhaul of the Start menu. The same update bakes Android phone controls directly into the Start experience, making Windows feel more cohesive for the millions who keep a phone next to their PC all day.

What’s Actually Changing in This Insider Build

This isn’t a minor quality-of-life patch. The build touches several pillars of the Windows 11 experience that have frustrated users since launch. Here’s what’s genuinely new.

WSL Containers: Linux Development Gets a Native Home on Windows

Windows Subsystem for Linux (WSL) already undercut the need to dual-boot for many developers, but container support takes that a step further. The new WSL container environment, now in public preview, adds a container runtime directly atop the existing WSL 2 architecture. Instead of spinning up a full virtual machine for container work, developers can create, run, and manage OCI containers inside the same lightweight VM that powers their WSL distributions.

Two technical wins stand out:

  • Virtiofs for faster file sharing. WSL 2 has long been plagued by sluggish performance when accessing Windows-side files. The 9P network protocol was designed for convenience, not speed. Virtiofs replaces it with a shared-memory model that significantly reduces serialization overhead, particularly for file-heavy workloads like npm installs or large Git operations. In practice, you can keep your project files in Windows without the penalty you’d feel in older WSL releases.

  • GPU and NPU access via CDI. Containers that need CUDA, DirectML, or other acceleration can now reach the host’s GPU through the Container Device Interface. That means AI inference, model training, and scientific compute jobs can run inside a Linux container with near-native performance—all while you keep Outlook and Teams open on the Windows desktop.

Microsoft made it clear this is built on real Linux tooling, not a proprietary reimplementation. The container runtime is OCI-compliant, so images you pull from Docker Hub or a private registry will work as expected. Commands to create, inspect, prune, and export containers are available directly from the terminal.

The Start Menu Finally Behaves Like a Modern App Launcher

Windows 11’s original Start menu felt like a compromise: cleaner than Windows 10’s live-tile chaos, but too restrictive for anyone who wanted to quickly browse installed software. The new build fixes that with three distinct app views:

  • Category view groups apps into broad buckets—Productivity, Utilities, Games, Entertainment, Developer Tools—based on a local JSON mapping file. There’s no cloud component, no AI, and no account requirement. It’s the kind of phone-like app library that makes a large software collection easier to scan.
  • Grid view presents icons in a visual, app-drawer-style layout. It’s ideal for touch or quick visual scanning.
  • List view gives you the traditional alphabetical list for those who want compactness above all.

Switch between them with a single click. The “Recommended” section has been renamed “Recent,” and you can now control exactly what appears—recently installed apps, recently opened files, usage tips, and browsing history can be toggled on or off independently. You can even hide account details like your name and profile picture. For anyone who’s hesitated to open the Start menu during a presentation, this is overdue.

Taskbar Freedom Returns—With a Few Caveats

For nearly three years, Windows 11 locked the taskbar to the bottom of the screen. The Insider build brings back the ability to move it to the top, left, or right edge. If you use an ultrawide monitor, prefer a GNOME-style top bar, or simply miss the vertical layout that gave you more lines of code, this is a fundamental improvement. A new compact mode reduces icon size and taskbar height, reclaiming pixels on smaller laptops and handhelds.

It’s not finished, though. Auto-hide behavior, touch gestures, and some flyout positioning still need polish. Microsoft is wise to keep this in testing until the entire surrounding ecosystem—search panel, system tray, notification area, and context menus—behaves reliably at every screen edge. For now, it’s an experimental toggle in Settings, not the default. But the direction is clear: Windows is no longer pretending that one size fits all.

Android Phone Integration Sits Right in Start

If you’ve used KDE Connect on Linux, you know the value of keeping your phone’s state visible on the desktop. Windows 11 now offers something similar directly from the Start menu: a compact panel showing battery level, connectivity, recent photos, messages, and call history for a linked Android device. You can drag the last 2,000 photos straight into a document or chat, and clipboard sharing works across devices.

There’s no third-party app to install; pairing happens through the existing “Show mobile device in Start” toggle under Personalization settings. While iPhone support is more limited, this tight Start menu integration makes Phone Link feel like part of the OS rather than an afterthought.

Why These Changes Matter for Your Workflow

For Everyday Users

The Start menu’s new views make finding apps less frustrating, especially on family PCs or tablets where dozens of programs accumulate. Turning off the recommendations means you won’t accidentally flash a sensitive document during screen sharing. And the Android panel saves you the hassle of emailing photos to yourself or hunting through cloud services.

For Developers and Power Users

WSL containers remove a major friction point. If your employer mandates Windows but your toolchain runs on Linux, you now have a credible container environment that doesn’t require Docker Desktop licensing juggling or a separate VM. GPU access through CDI also means you can prototype AI workloads without a dedicated Linux box. When combined with the improved file-system performance from virtiofs, day-to-day development feels less like a compromise.

Taskbar placement matters here, too. As a developer, you might want a vertical taskbar on the left to maximize vertical space for code. Or a top bar that mirrors your Linux workstation. The compact mode further increases the usable canvas on 14-inch laptops.

For IT Administrators

These features don’t turn Windows into a free-for-all, but they do require planning. WSL containers rely on Hyper-V and virtualization extensions, which may conflict with corporate security policies or existing Type-2 hypervisors. The Start menu’s local categorization data is unlikely to cause compliance headaches, but you’ll want to test whether the new layout confuses users or aligns with your org’s training materials. Group Policies or MDM settings to lock down specific Start menu views aren’t mentioned yet, so stay tuned.

How We Got Here

Windows 11 launched in 2021 with a simplified taskbar and Start menu that many power users found regressive. Microsoft’s telemetry likely showed that most people never moved the taskbar, but the vocal minority was loud: feedback hubs filled with requests, third-party utilities like StartAllBack flourished, and Linux distributions saw an uptick in interest from disgruntled Windows users.

WSL 2 itself was a peace offering to developers forced to use Windows laptops. It already blurred the line between operating systems, but container support was an obvious next step—especially as cloud-native development became the default. The devblogs.microsoft.com team teased container work in May 2024, and this Insider build delivers the public preview.

Meanwhile, Android phone integration has evolved slowly since the Your Phone days. The Start menu panel is a logical escalation: if the PC is the hub, the phone belongs right there, not buried in an app.

What to Do Now

  • If you’re on the Insider Dev or Beta channel, look for the toggle in Settings > Personalization > Taskbar to enable movable taskbar and compact mode. Expect rough edges.
  • To test WSL containers, you’ll need to update WSL from the Microsoft Store or run wsl --update from an elevated terminal. Then follow Microsoft’s devblog for container-specific commands (wsl --container and others). The feature requires a build with the container runtime; it’s rolling out to Insiders gradually.
  • For the Start menu, simply click the All apps button and choose a view. The category file lives at C:\ProgramData\Microsoft\Windows\Start Menu\Apps as a JSON mapping—you can inspect it, but don’t modify it unless you’re prepared for breakage.
  • Link your Android phone by going to Settings > Personalization > Start and enabling “Show mobile device in Start.” You’ll need the Link to Windows app on your phone and a signed-in Microsoft account.
  • Stable-channel users: most of these features are not yet available in Windows 11 24H2 or earlier. They’re expected to arrive in a future feature update, possibly 25H2 or later, but no firm date has been announced. Waiting is the prudent path if you rely on your PC for daily work.

What’s Next

Microsoft’s Insider builds often reveal the company’s true priorities, and this one screams “productivity and developer flexibility.” The taskbar work isn’t final, and the WSL container experience will need to prove itself against mature alternatives like Docker Desktop and Podman before enterprises embrace it. But the direction is undeniable: Windows is shedding its locked-down reputation and embracing the workflows that have kept Linux alive on so many desktops.

Watch for further integration of AI-related tooling into WSL (the devblog hints at NPU access), and expect the movable taskbar to become a banner feature of the next major Windows 11 release. For now, these updates give every Windows user—whether you code for a living or just want your taskbar on the left—something to look forward to.
