Microsoft has reduced a known problem, which caused Windows update failures when installing them from network share using Windows update standalone installer (Wusa).
Wusa is a built-in command-line tool that helps to install and uninstall the Microsoft Standalone (.MSU) files through Windows update agent API to deploy and remove patch, hotfix and updates.
This known problem affects Windows 11 24H2 and Windows Server 2025 system on enterprise networks, as Wusa is not a common way to install Windows updates on home equipment.
“Windows update updated standalone installed using the Windows update error error using the update standalone installer (Wusa), when the update is installed using Wusa or a. MSU file from a network share is installed by dubbly-clicking, which contains many .MSU files,” Redmond said Release health dashboard on Windows.
“These issues can occur on devices that have been installed on 28 May, 2025 (KB5058499) and later updates.”
The company said that this problem is not with single .MSU file or when files are stored locally. Additionally, another issue that should resolve on its own, is that the update history page can temporarily show that a .MSU file is required to be installed and Windows requires a restart after restarting Windows.
Fix available through the known digit rollback
While a fix for this bug is not yet available, Microsoft is automatically lowering it on home and non-managed business equipment by rolling out a fix through the known problem rolback (KIR).
It can also solve praise Problem on managed equipment established and configured This known digit rollback group policy Affected Windows 11 24h2 and Windows Server 2022 equipment.
As a workaround, people who prefer to get the fix through future Windows updates can also save .MSU files locally .MSU files and install Windows updates from that location.
In recent months, admins have experienced many other issues when trying to install Windows updates. For example, in April, Microsoft resolved another issue to prevent the April 2025 security update on the Windows 11 22H2/23H2 system from setting up the April 2025 security update through the Windows Server Update Services (WSUS).
The company fixed a uniform bug, which failed with 0x80240069 errors when distributed via WSUs due to the WSUS due to the wsus.
