Users of Microsoft Excel 2016 and Excel 2024 LTSC Professional report that the September software update has caused significant functionality issues. The primary problems involve the inability to copy, paste, or select cells within the spreadsheet application.
Some users also report that the automatic fill feature has stopped working correctly. According to reports from the BornCity blog, the technical failure is likely linked to the KB5002914 update, which Microsoft released to address security vulnerabilities.
The KB5002914 patch was originally intended to fix remote code execution and information disclosure flaws. For users running the MSI version of Office 2016, uninstalling this specific security update restores normal functionality to Excel.
