As part of the March Patch cycle, Microsoft is rolling out a new cumulative update for all supported version of Windows. In this month’s update, there are only security enhancements for the system, browsers, core components and other basic functions. Microsoft noted that the patch also includes quality improvements to the servicing stack, which is the component that installs Windows updates. After installing Windows updates from March 9, 2021 and later, print jobs that are in a pending state before restarting the print spooler service will remain in an error state.
