What happened

A regression in Excel 2016 caused paste operations to fail silently, first appearing in the September update and reappearing with October's KB5002934. The bug was reintroduced in build 16.0.5574.1005, where paste could fail if the workbook contained conditional formatting. Microsoft's fix is build 16.0.5574.1006, which also includes all current Excel 2016 security updates. Only Excel 2016 is affected, and the issue came through Windows Update rather than the Windows security update itself. Rolling back the update was a temporary workaround.
