Microsoft resolved an issue causing installation failures and error code 0x800f0922 during the deployment of the May 2026 Windows 11 security update (KB5089549), which was linked to insufficient free space on the EFI System Partition (ESP). The problem mainly affected devices with 10 MB or less available space, leading to automatic rollbacks of the update. The resolution was provided through the release of the Windows 11 KB5089573 preview cumulative update on May 26, 2026. Users installing updates released on or after this date will not need a workaround, while those with earlier updates can use the Known Issue Rollback feature. Additionally, IT administrators in enterprise settings can manually address the issue through Group Policy configurations. The KB5089573 update introduced 30 changes to improve performance and reliability.

Microsoft has identified the root cause of installation issues related to the May 2026 update for Windows operating system and is rolling out a solution through an optional update, KB5089573. The May 12, 2026, Patch Tuesday update (KB5089549) introduced enhancements but many users faced installation failures due to error code “0x800f0922,” indicating insufficient space on the EFI System Partition (ESP). The ESP is critical for boot files and typically occupies around 256MB. Users can check ESP storage using a specific command. Low ESP space can lead to update failures, particularly when it drops below 10MB. Microsoft has rolled back problematic code and provided a fix in the optional update KB5089573, which resolves ESP space issues and ensures future updates will proceed smoothly. Users are encouraged to install this update or wait for the next scheduled Patch Tuesday update on June 9, 2026.

Microsoft has released Windows 11 Insider Build 26300.8553, featuring a redesigned Start menu that addresses user complaints about customization and performance.

Users can also disable Pinned apps and All apps, leading to a minimalist Start menu. Three size options for the Start menu are available: Automatic, Small, and Medium. The All apps section can be viewed in Grid or List format. Users can hide their name and profile picture from the Start menu. A native Start menu is in development, with plans to use native WinUI 3 frameworks for improved performance.

Windows 11 has introduced a feature allowing multiple applications to access the camera simultaneously, which will be available to all users with the June 2026 Patch Tuesday. Previously, only one application could use the camera at a time, causing issues for users wanting to use multiple apps like Microsoft Teams and OBS. Users can enable this multi-camera mode by navigating to Settings > Bluetooth & devices > Cameras and toggling the advanced settings. Microsoft is also working on improving the reliability of camera and audio connections and has introduced a "Basic Camera" feature to help diagnose camera problems related to driver issues. These enhancements are part of the Windows 11 KB5089573 (May 2026 optional update) and are being rolled out gradually.

Microsoft has introduced a new feature called "Shared Audio" for Windows 11, allowing two Bluetooth headsets to share audio simultaneously. This feature utilizes Bluetooth LE Audio technology, enabling two users to connect their Bluetooth audio devices to a single Windows PC and enjoy the same audio stream while independently adjusting the volume. The rollout of this feature is gradual, and users may not see it immediately after installing the optional update KB5089573. Compatibility requires both the PC and connected audio devices to support audio broadcasting. Additionally, the update includes an enhancement known as the Low Latency Profile to improve performance on Windows 11 devices.

Microsoft is refining Windows 11 based on user feedback, planning to reintroduce a smaller taskbar and resize controls similar to Windows 10. Early signs of these changes are evident in preview builds, specifically in Windows 11 Build 26300.8346, which features a compact Widgets button. Currently, Windows 11 allows for smaller taskbar buttons but not a smaller taskbar overall. Upcoming updates aim to restore the full functionality of the Windows 10 taskbar. Microsoft has acknowledged past missteps and is committed to enhancements, including improved performance and a more efficient File Explorer. Up to 18 major changes are being tested for Windows 11, with some already implemented in the April 2026 update, which includes improvements to system tray loading, Windows Hello reliability, and performance issues in File Explorer. Future changes will also focus on reducing advertisements and enhancing user experience.
