The KB5083769 security update released in April 2026 has disrupted the functionality of various third-party backup applications on Windows 11 versions 24H2 and 25H2, primarily due to issues with the Volume Shadow Copy Service (VSS). Affected applications include Acronis Cyber Protect Cloud, Macrium Reflect, NinjaOne Backup, and UrBackup Server. Users have reported receiving an error message indicating that backups have failed due to VSS timeouts. Acronis has acknowledged the issue, stating it affects both Windows 11 Pro and Home editions, and warns of potential broader system issues. A temporary solution involves uninstalling the KB5083769 update or pausing Windows updates. Additionally, Microsoft has issued out-of-band updates for critical issues affecting Windows Server systems and warned that some Windows Server 2025 devices may encounter BitLocker recovery prompts after installing the KB5082063 update.

The April update KB5083769 for Windows 11 versions 24H2 and 25H2, released on April 14, 2026, has a known issue where certain devices may enter BitLocker recovery mode after installation. This problem affects a limited subset of devices with specific, non-recommended BitLocker Group Policy settings. The issue arises when BitLocker is activated, a specific TPM platform validation policy is set to include PCR7, PCR7 binding is not feasible, the Windows UEFI CA 2023 certificate is present, and the device is not using the 2023-signed Windows Boot Manager. Microsoft advises organizations to review their BitLocker Group Policy settings and verify PCR7 binding status before deploying the update to prevent devices from requesting recovery keys. If the recovery prompt appears, users will need to enter the BitLocker recovery key, but subsequent reboots should not trigger the recovery process again if the Group Policy remains unchanged.

Windows 11 has become the preferred operating system for many users after the discontinuation of Windows 10, though its adoption has faced challenges due to strict hardware requirements and design inconsistencies. The customization landscape for Windows 11 is growing, largely driven by third-party developers responding to perceived shortcomings in Microsoft's offerings. Debloater applications, which remove unnecessary pre-installed apps, have gained popularity, with tools like Winhance being noted for their user-friendliness. Users are seeking straightforward scripts and custom Windows ISOs to simplify their experience, with recommendations including AtlasOS, FoxOS, ReviOS, and GGOS. AtlasOS is highlighted as a lightweight modification that aims to enhance performance and privacy by eliminating telemetry and unnecessary background processes. Users can expect improved CPU performance and higher framerates in games, but there are risks associated with using third-party modifications, such as potential security vulnerabilities and missing feature updates. Microsoft has made it easier to bypass mandatory updates during setup, while continuing to refine Windows 11 with new features. The ongoing evolution of Windows 11 customization raises questions about whether these enhancements will reduce the appeal of custom ISOs like AtlasOS.

A series of updates have been released, focusing on system integrity and performance. Users should perform verification tasks, including installing, uninstalling, and repairing MSI packages, connecting and disconnecting cloud sync providers, and enrolling devices in Intune or MDM solutions. The Common Log File System driver (clfs.sys) is receiving a follow-up patch, along with updates to Storage Spaces (spaceport.sys) and app isolation file system drivers (bfs.sys, wcifs.sys). Users should also run Windows Update installation and rollback cycles, install and uninstall applications, and verify data integrity through backup solutions. For Storage Spaces, creating a pool with mirrored and thin virtual disks and ensuring clean deletion is necessary. April's updates for Office target MSI editions, including Excel 2016 (KB5002860), PowerPoint 2016 (KB5002808), Office 2016 shared libraries (KB5002859), and SharePoint Server editions from 2016 to 2019. These updates do not apply to Click-to-Run deployments like Microsoft 365 Apps. Users should validate complex Excel workbooks, PowerPoint presentations, SharePoint document libraries, and the functionality of Office add-ins. Testing for two High Risk components is essential: changes to Kerberos may disrupt services using RC4 keytabs, and the Remote Desktop client update requires validation of clipboard functionality, printer redirection, and session reconnection. Validating Secure Boot and BitLocker is critical as CVE-2023-24932 key rolling progresses. Additionally, cloud sync testing is important due to five patches to the Projected File System driver, and regression testing is needed for dual afd.sys updates and VPN/IPsec patches across remote-access infrastructure. Office updates are limited to MSI editions.

Microsoft has programmed its Edge browser to automatically launch after a Windows 11 update, displaying a page that informs users their update is complete and prompts them to explore new features. This page lacks a close button, directing users to click a blue "Next" button to proceed. The features highlighted include the reinstatement of the taskbar clock, the ability to pin Emojis to the taskbar, Copilot's document summarization, the Snipping Tool's Quick markup, and AI actions in File Explorer's context menu. Users can provide feedback via like and dislike buttons, but these do not close the page. Windows 11 also includes pre-installed Get Started and Get Help apps that could showcase features instead of redirecting users to Edge. Edge, built on the Chromium engine, supports all extensions from that platform and includes features like AI tab organizer, Vertical Tabs, and Immersive Reader.

A recent Microsoft security update, April 2026 KB5082063, has caused issues for administrators of Windows Server 2025 and Windows 11 systems, with many devices entering BitLocker recovery mode after reboot, requiring a 48-digit recovery key. This issue primarily affects enterprise-managed systems with specific TPM Group Policy settings involving PCR7 validation. Similar problems have been reported with updates KB5083769 and KB5082052 on Windows 11. The issue arises from five conditions: BitLocker must be enabled on the OS drive, the Group Policy must include PCR7, the msinfo32.exe tool must show Secure Boot State PCR7 Binding as “Not Possible,” the Windows UEFI CA 2023 certificate must be in the Secure Boot Signature Database, and the device must not be using the 2023-signed Windows Boot Manager. Microsoft suggests two workarounds: removing the TPM validation Group Policy before the update and re-enabling BitLocker, or applying a Known Issue Rollback (KIR) before installation. Skipping the April updates is not advisable due to the addressing of 167 vulnerabilities, including two zero-days. BitLocker recovery issues following updates have been recurring since 2022, with similar incidents reported in August 2022, August 2024, and May 2025, indicating ongoing challenges with Secure Boot certificates and TPM validation bindings in enterprise environments.

Microsoft has implemented a server-side remedy for an issue affecting the Windows Start Menu search functionality on select Windows 11 23H2 devices, which began impacting users on April 6. The problem was linked to a server-side Bing update aimed at improving search performance. Microsoft has rolled back the problematic Bing update and expects search issues to decrease as the fix is deployed. Users have reported blank search results in the Start Menu, but options remain clickable. Microsoft confirmed that the issue will resolve automatically with the rollout of the fix, provided devices are connected to the internet and Web Search is enabled. Additionally, there have been previous Start Menu-related issues, including crashes and error messages, with Microsoft working on permanent solutions for these problems.
