Windows 11 update is breaking some PCs with boot and BitLocker issues

Windows 11 update KB5094126 (Build 26200.8655), released on June 9, 2026, has caused boot failures, blue screens, and BitLocker recovery prompts for users, particularly affecting business devices from HP and Dell, including models like HP EliteBook 840 G10 and Dell Precision 7530. The issues stem from changes in Secure Boot and EFI partition modifications, with insufficient EFI partition space leading to errors. A workaround involves disabling Secure Boot in BIOS. Additionally, users have reported disruptions with OneDrive and Microsoft Word integration, particularly in enterprise environments. Microsoft has not yet acknowledged these problems.

Windows 11 KB5094126 BSODing, freezing, forcing BitLocker lockout, breaks OneDrive, and more

Microsoft rolled out Patch Tuesday updates for Windows 11, specifically KB5094126 and KB5093998, along with dynamic updates KB5094149, KB5095971, and KB5094156. Users have reported various issues post-update, including access difficulties with OneDrive and Dropbox, BitLocker recovery lockouts, and blue screens of death (BSOD), particularly the 0xc0430001 error on HP systems. This error may be linked to a previous bug affecting HP devices related to Secure Boot certificate updates. Users experiencing this error are advised to verify the presence of the boot.stl file on their installation media, as it is essential for Secure Boot. Microsoft recommends using the Update WinPE script to ensure the boot.stl file is included or manually transferring it from the WindowsBootEFI directory. Additionally, some Lenovo PC users have reported system freezes after the update. One user identified a conflict between KB5094126 and User Account Control (UAC) that affects OneDrive and Dropbox access in Explorer, noting that enabling UAC resolves the issue.

Microsoft confirms Windows 11 update is failing on some PCs, explains if you need a workaround

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 is killing the one-app-at-a-time camera limit in Windows 11 with new Multi-App mode

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.

A Windows 11 bug blocks all updates since February. Here’s what to do

A segment of Windows 11 users has been unable to receive updates since February due to issues stemming from the January Preview Update, which caused download timeouts. This has resulted in missed security patches and critical updates related to Secure Boot certificates. Users may experience crashes during the update process, indicated by the error code 0x80010002. To check if affected, users can view their update history in Settings; if no updates have been installed since January and updates have not been paused, they are likely impacted. Microsoft is working on a fix linked to download timeout changes and firewall settings. A Known-Issue Rollback (KIR) can be executed to revert to a previous state before the problematic update, restoring normal functionality. This rollback is available for specific Windows 11 versions and Windows Server 2025.

Microsoft confirms Windows 11’s May 2026 update is failing to install with error 0x800f0922 and outlines a mitigation for affected PCs

Microsoft has acknowledged installation issues with the May 2026 Security Update for Windows 11, specifically error code 0x800f0922, affecting devices on versions 24H2 and 25H2 after installing update (KB5089549) released on May 12. The failures occur during the reboot phase, often around 35 percent, primarily on devices with 10MB or less free space in the EFI System Partition (ESP). For consumer and unmanaged business devices, Microsoft has implemented a Known Issue Rollback (KIR), and restarting the computer may resolve the issue. For managed devices, network administrators must manually deploy a Group Policy workaround. Microsoft suggests modifying a Registry value to decrease reserved padding in the EFI partition as a potential fix, along with restarting the computer and checking for updates. A permanent solution is planned for a future Windows update.

Microsoft confirms patching issues in restricted Windows networks

Microsoft has issued a service alert indicating that customers in restricted network environments may encounter Windows Update failures, specifically error code 0x80010002, after installing the January 2026 optional non-security preview updates. Affected devices might download the February monthly Windows security update but could struggle with updates released in March and beyond due to changes in download timeout requirements. Microsoft is working on a resolution, and IT administrators can use Known Issue Rollback (KIR) as a workaround by configuring the appropriate Group Policy for their Windows version. A device restart is required to apply these settings. Historical issues include a bug fixed in April 2025 affecting WSUS installations and another issue resolved in August 2025 related to the Windows 11 24H2 cumulative update. Additionally, a KIR fix was provided for a known issue causing the May 2026 Windows 11 security update to fail with error code 0x800f0922.
