Microsoft released update KB5005932 for Windows 10 in 2004, 20H2, and 21H1 on August 24, 2021. This update fixes error 0x800F0984 (PSFX_E_MATCHING_BINARY_MISSING), which prevents updates from being installed on Windows 10.
This bug is present in different versions of Windows 10 (since 2004). The update is optional and will not be done automatically.
Microsoft has published the support page KB5005322 entitled KB5005322 - Some devices cannot install new updates after installing KB5003214 (May 25, 2021) and KB5003690 (June 21, 2021). In the support article, it states that installing updates KB5003214 and KB5003690 may prevent new cumulative updates (eg KB5004945, released on July 6, 2021, or other newer updates) from being installed on Windows 10.
Microsoft recommends that all affected users make an in-place upgrade of the system. The in-place upgrade installs Windows 10 on top of the existing Windows 10 system, so the existing older version is replaced or repaired. This approach preserves system files, applications, and settings.
On August 24, 2021, Microsoft added to the support page that an in-place upgrade only helps systems that have been online for the past 30 days.
The company states that update KB5005932 is available for Windows 10 version 2004, 20H2 and 21H1. The update also includes a compatibility fix for Windows Setup in Windows 10 of the above versions. This allows the in-place upgrade to run on devices that cannot complete the installation of the latest cumulative update.
The update is available in the Microsoft Update Catalog. Microsoft is not aware of any issues with this update.
