Look out for KB4023057: it is being released again for Windows 10 by Microsoft
In Groundhog Day, Phil Connors is trapped in a time loop in which he relives the same day over and over again. Some Windows 10 administrators may feel the same way when it comes the the Windows 10 update KB4023057, which Microsoft releases regularly anew.
Two mention just two previous events: In September 2018, Microsoft pushed the update to supported versions of Windows 10, and revealed little about the update itself, only that it addressed issues that could prevent "important Windows updates from being installed".
In August 2020, the update was released again, with the same description and no new information, other than the updated list of supported Windows 10 versions.
