Description

The Microsoft Excel KB5002914 security update released in September 2026 has caused issues with copy-and-paste operations and formula dragging for some users. The problem affects multiple Office versions including 2016 through 2024 and both MSI and Click-to-Run installations. Users report that uninstalling or rolling back the update restores normal functionality. No official Microsoft fix or workaround has been confirmed yet.

Impact

The update disrupts core Excel functionalities such as copy-and-paste and formula dragging, which can significantly hinder productivity for affected users. The issue blocks normal workflow in Excel but does not represent a security vulnerability or exploit. There is no evidence of exploitation or security compromise related to this update.

Defensive guidance

Affected users can uninstall or roll back the KB5002914 update to restore Excel functionality. For MSI-based Office installations, uninstalling the update via provided PowerShell commands has been effective. For Click-to-Run installations, downgrading the Office build using XML or Group Policy is a workaround. Replacing the excel.exe executable with an older version is not recommended due to potential stability and security risks. Monitor official Microsoft channels for updates or patches addressing this issue.
