Microsoft: WUSA may fail to install recent Windows updates

Microsoft is addressing an issue with the Windows Update Standalone Installer (WUSA) that affects the installation of Windows updates from network shares, primarily impacting Windows 11 24H2 and Windows Server 2025 systems in enterprise networks. The problem leads to updates failing with the error ERRORBADPATHNAME when multiple .msu files are present on a network share. This issue does not occur with single .msu files or local installations. A Known Issue Rollback (KIR) is available to mitigate the problem for home and non-managed business devices, while IT administrators can implement a Group Policy fix for affected systems. Users can also avoid the issue by saving .msu files locally for installation.
