Have you found yourself unable to copy and paste in Microsoft Excel after installing the latest update? Don’t worry; it’s likely not an issue with your keyboard or computer.
Understanding the Issue
Microsoft has confirmed that the September 2026 security update, identified as KB5002914, may cause the paste function in Excel to malfunction without any warning. This problem affects various versions of Excel, including 2024, 2021, 2019, and 2016. The company has acknowledged this bug and included it in the known issues list for KB5002914, stating that they are currently investigating the root cause.
User Reports and Impact
Reports of the issue began surfacing on forums such as Reddit and Microsoft Q&A shortly after the security update was released. Users have not only complained about the inability to copy and paste, but they also reported that the autofill feature and formula manipulation tools are no longer functioning as expected.
What Happens During the Bug?
This bug can be particularly frustrating because Excel does not provide any warning or error message when the paste function fails. While users are still able to copy data, attempting to paste it results in no change to the target cell. Microsoft explained that the source data remains highlighted during the bug occurrence, which adds to the confusion.
Release and Consequences of the Update
KB5002914 was released on September 8, 2026, as a crucial security update for Excel 2016 using the Microsoft Installer (MSI). This update is significant as it addresses various vulnerabilities in Excel, including those that could allow for remote code execution and information disclosure.
As of now, Microsoft has not provided a fix for the copy-paste bug. The company mentions that it is still looking into the matter and will update its support page when more information becomes available.
Temporary Solutions and Risks
Some users have reported that their copy-paste functionality returned to normal after uninstalling KB5002914 from their MSI-based Office installations. Others experiencing similar issues with Click-to-Run Office versions found that reverting to a previous build restored the Excel features.
However, uninstalling a security update is not without its risks. KB5002914 also included fixes for several security vulnerabilities in Excel, meaning that removing it could potentially reopen previously patched security holes.
Therefore, users who are not significantly impacted by the bug may want to consider waiting for an official fix from Microsoft rather than immediately uninstalling the security update.
