Representatives of Microsoft announced the suspension of distribution for the optional update KB5079391 after it was available for a few hours due to user complaints about a critical installation error. Users reported interruptions during the update process and received a message about missing system files, with a common error code of 0x80073712 indicating damage or absence of essential components in the WinSxS system folder. Microsoft has initiated an internal investigation and temporarily restricted access to the update through the Windows Update service. There is currently no estimated timeline for resolving the issue. Microsoft is also working on future enhancements, including improving the Start menu's performance, reducing File Explorer's loading time, and allowing users to pause patch downloads for several months.
