Microsoft fixes broken copy and paste for Excel 2016 users
Microsoft released KB5002655 fixing silent copy-and-paste failures in Excel 2016 caused by the September 2026 KB5002914 security update.
Microsoft confirmed that the September 2026 KB5002914 security update caused a code regression breaking copy-and-paste, autofill, and formula dragging in Excel 2016/2019/2021/2024 and Excel Online. The new KB5002655 fix only addresses the bug for MSI-based Office 2016 editions, not Click-to-Run or other versions, for which Paste Special (Ctrl+Alt+V) is the suggested workaround. Uninstalling KB5002914 also restores paste functionality but removes remote code execution and information disclosure patches.
