Microsoft Excel Security Update Breaks Copy-Paste and Formulas

Issues with the KB5002914 update

A security update released by Microsoft this week, identified as KB5002914, has caused unexpected technical disruptions for Office users. As reported by BleepingComputer, many Excel users noticed after updating the application that copying and pasting data no longer functions properly.

Additionally, the bug has affected the drag-and-drop formula copying feature across cells, an essential part of daily work for many. Some users report that the program fails to respond to commands or executes functions incorrectly, significantly hindering workflow.

How to resolve the issue

Fortunately, a temporary workaround is already available. According to affected users, the issue can be completely resolved by uninstalling update KB5002914 directly or rolling back the system to a previous version. Once removed, Excel functions return to normal.

Microsoft has not yet released an official statement or an updated patch to address the bug. If you experience this issue on your workstation, checking your update log and temporarily uninstalling the package is recommended until an official fix is released.

Incidents like this serve as a reminder of how crucial staged update rollouts are in corporate environments to prevent widespread operational disruptions.
