Microsoft rolled out a new experimental preview build for Windows 11 Insiders on May 29, 2026, delivering one of the most significant Start menu overhauls since the operating system’s launch. Build 26300.8553 introduces dedicated controls to resize the Start menu panel and toggle the visibility of the Pinned, Recent, and All Apps sections. The update lands in the Dev or Canary channel—Microsoft hasn’t specified the exact branch yet—and marks a sharp turn toward genuine user customization after years of feedback demanding more layout flexibility.

Insiders who receive the build gain immediate access to a fresh set of sizing options. The Start menu no longer adheres to a fixed width, instead offering at least three predefined sizes—compact, standard, and expanded—according to early reports from testers. Enthusiasts may also discover a drag handle at the edge of the menu, although Microsoft is expected to fine-tune the interaction model before wider release. Alongside the size controls sit three checkboxes buried in the Settings app under Personalization > Start. Each toggle controls a distinct zone: Pinned apps, Recommendations/Recent files, and the All Apps list. Turning off Recent removes the suggestions row that often displays recently opened documents and apps, a long-requested privacy win. Disabling Pinned streamlines the menu to a minimalist launcher, while hiding All Apps reverts the experience closer to the classic Windows 10 style, where typing brought up a full list.

The experimental nature of Build 26300.8553 means it won’t show up automatically for every Insider. Testers must enable the “Get the latest updates as soon as they’re available” toggle in Windows Update and be on a supported hardware configuration. Even then, Microsoft frequently seeds such builds to a subset of users to gather comparative telemetry. Once installed, the new controls appear gradually—some Insiders may see them immediately, while others will need to reboot or wait for a feature flight flag to flip server-side.

A Long Road to Start Menu Freedom

The Start menu has been the central launchpad for Windows users since Windows 95, and its evolution in Windows 11 has been particularly contentious. When Microsoft unveiled Windows 11 in 2021, it abandoned the live tiles of Windows 10 in favor of a grid of static icons and a “Recommended” section. The redesign forced a center-aligned, non-resizable panel that polarized longtime fans. Early Insider builds quickly added back the ability to move the Start button to the left, but the menu itself remained stubbornly rigid.

Over the next few years, cumulative updates and minor feature drops tacked on incremental improvements: app folders appeared in October 2022, and a “more recommendations” option briefly surfaced before being pulled. The 2023 “Moment 4” update finally allowed users to reduce the Recommended area’s height, but full section hiding stayed hidden behind registry hacks and third-party tools like Start11. Build 26300.8553 represents the first official acknowledgment that users want to choose exactly which Start menu components they see.

How the New Controls Work

The resize mechanism is the headline act. Early testers can grab the right or bottom edge of the Start menu and drag it to a custom width and height, similar to resizing a regular window. The icons and text reflow responsively: a narrow menu stacks app icons in a single column, while a wider layout shows three or more columns and displays the full app name beneath each icon. The menu also remembers its last position, so users can define a default size and have it persist across sessions.

The section toggles live in a new “Layout” dropdown inside Start settings, alongside the familiar grid size options for more or fewer pins. Each section comes with an individual on/off switch. Flipping off Recommendations not only hides the recent files list but also reclaims that vertical space, pushing the Pinned area upward. When a user disables All Apps, typing in the search box still returns an app list, but the dedicated All Apps button vanishes from the menu. The Pinned section behaves similarly: turn it off, and the Start menu becomes a search-first launcher with nothing but the search bar and power button visible by default.

Privacy Gains and User Backlash

One of the most vocal requests over the years has been the ability to permanently banish the Recommended section. Windows 11’s default behavior populates this area with recently opened files and apps, which can be a privacy nightmare on shared or publicly visible screens. While users could previously reduce the section’s size, there was no official way to eliminate it entirely. Build 26300.8553 changes that, giving privacy-conscious users a clean Start menu free of file trails.

However, the feature isn’t without potential friction. Power users who rely on the Recent list to quickly jump back into documents may feel disoriented if they accidentally disable it. Microsoft is reportedly adding a subtle “What’s new” tip that appears on first toggle, explaining where to re-enable the section. Some Insiders have already voiced concerns on the Windows Insider subreddit that the new checkboxes are too easy to find, risking accidental changes for less technical users. Microsoft’s telemetry will likely shape whether these toggles remain so prominent or get tucked behind an “advanced” dropdown before the build hits stable.

The Experimental Build Landscape

Build 26300.8553 belongs to a relatively new category Microsoft calls “Experimental Preview Builds.” These builds ship features that aren’t necessarily tied to a specific Windows release cycle; instead, they serve as a testbed for A/B experiments and rapid design iteration. Similar experimental builds over the past year have tested a floating taskbar, a redesigned system tray, and an AI-powered clipboard—some of which never made it past the trial phase. The Start menu controls, however, address such a high-priority feedback item that they’re almost certain to graduate to a wider Dev build and eventually the Beta channel.

Testers should expect rough edges: the drag-to-resize animation occasionally stutters on older GPUs, and the Pinned apps section may temporarily lose its icons after resizing, requiring a manual refresh. Microsoft has already acknowledged a known issue where the All Apps list’s letters grid fails to render correctly at certain widths, promising a fix in the next update.

How to Experience Build 26300.8553

If you’re already a Windows Insider on the Dev or Canary channel, head to Settings > Windows Update and check for updates. After installing, navigate to Settings > Personalization > Start to find the new “Layout” dropdown. If the options don’t appear, try toggling the “Show recently opened items in Start, Jump Lists, and File Explorer” option off and back on—it sometimes forces a UI refresh. Power users can also restart Explorer.exe via Task Manager to reload the Start menu components.

For those not in the Insider program, joining requires a Microsoft account and a device meets the hardware requirements (TPM 2.0, Secure Boot, supported CPU). Enrolling puts your device on a flight that receives frequent, often unstable builds, so backup your data before taking the plunge. The control to hide sections should make its way to the Release Preview channel within a few months, Microsoft’s typical incubation period for high-demand features.

What This Means for Windows 11’s Future

The arrival of Start menu customization isn’t just a quality-of-life improvement—it signals Microsoft’s broader willingness to loosen the design guardrails that defined the early Windows 11 era. Under Satya Nadella’s leadership, Microsoft’s product philosophy has increasingly embraced user agency, from the AI-powered Copilot integration to the recent overhaul of File Explorer’s tabs. The Start menu controls slot neatly into that narrative, proving that the company listens—even if the response takes five years.

Analysts expect these options to spur a wave of third-party customization tools to add even more granular control, such as the ability to resize the Pinned section independently or inject web widgets. Microsoft’s own PowerToys suite might eventually offer a Start menu module if demand persists. For everyday users, the build marks the moment Windows 11 finally sheds its one-size-fits-all straitjacket. With a resizable, section-aware Start menu, the operating system inches closer to the personalization power that long defined Windows, without sacrificing the clean, modern aesthetic that won over millions.

As Build 26300.8553 percolates through the Insider rings, Microsoft will be watching feedback closely. Whether these controls reach the general public in their raw form or get refined with additional polish, one thing is clear: the Start menu is once again a canvas, not a mandate.
