Microsoft has acknowledged that the April 2026 security updates have disrupted the functionality of various third-party backup applications using the psmounterex.sys driver, raising concerns among users. The issue primarily affects software leveraging the Volume Shadow Copy Service (VSS) snapshots, leading to failures due to VSS service timeouts. Notable impacted products include Macrium Reflect, Acronis Cyber Protect Cloud, UrBackup Server, and NinjaOne Backup, used on Windows 11, Windows Server, and Windows 10 devices. Disruptions can manifest as failures to mount backup image files, errors or timeouts when browsing or restoring from backup images, and error messages related to VSS timeouts. Microsoft updated its support documentation to clarify that the April updates included a security hardening change that added psmounterex.sys to the vulnerable driver blocklist to protect against a high-severity buffer overflow vulnerability (CVE-2023-43896). Affected users are advised to upgrade to newer application versions with updated drivers and not to uninstall or pause the security update. Users can check if the Microsoft Vulnerable Driver Blocklist is blocking a driver by looking for Event ID 3077 in the Code Integrity Operational log. Additionally, Microsoft has alerted users that some Windows Server 2025 devices may boot into BitLocker recovery mode after installing the KB5082063 update and has issued out-of-band updates to address installation failures and restart loops affecting Windows Server systems after the April 2026 updates.

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.

Samsung's Enhance-X app for photo and video editing recently received an update that includes a new interface, plugins, and expanded editing options. However, users in the United States, Korea, and Israel have reported issues such as installation failures and crashes after the update, with some experiencing an update loop that prevents access to new features. While not widespread, these issues suggest potential problems in Samsung's update process. Some users have successfully installed the update, and an alternative solution for those facing difficulties is to sideload the APK to bypass the Galaxy Store update issues.

Microsoft is updating devices running Windows 11 version 24H2 to version 25H2, as support for 24H2 will end on October 13, 2026. The automatic update targets Home and Pro editions, while organizational devices are exempt. An "intelligent" system using machine learning will determine device readiness for the update, though details on the criteria remain unclear. Additionally, Microsoft released an emergency update, KB5086672, to address issues from a previous faulty update, KB5079391, which caused installation failures.

Microsoft veteran Raymond Chen discussed how Windows 95 handled installers that overwrote crucial system files. The operating system was designed to allow installers to compare version numbers, permitting overwrites only if the new file had a higher version. However, many installers ignored this rule, often replacing Windows 95 components with outdated Windows 3.1 versions, causing significant system issues. Windows 95's commitment to backward compatibility meant that preventing file operations could disrupt installers, leading to installation failures or error messages for users. To address these challenges, Microsoft created a hidden directory, c:windowssysbckup, to store commonly overwritten files. After an installation, Windows would check version numbers and replace lower versions with higher ones, maintaining system integrity despite third-party installer chaos.
