## Key points

- Excel 2016’s paste failure has returned and been fixed again.
- The latest repair is build 16.0.5574.1006.
- The failure affected workbooks containing conditional formatting.

## Summary

Microsoft has released another fix for a copy-and-paste failure in Excel 2016, after an earlier repair was undone by a later update. The problem meant users could copy content but pasting it into a workbook did not change the destination cell.

The latest build, 16.0.5574.1006, fixes the issue when a workbook contains conditional formatting. The bug returned after an Excel update delivered through Windows Update; it was not caused by the latest Windows security update. Users had reported it after the October update KB5002934, which addresses security vulnerabilities including remote code execution and information disclosure.
