MICROSOFT EXCEL UPDATE BREAKS COPY-PASTE

The KB5002914 update, released this week as part of Microsoft's Office security patches, is causing widespread issues with basic Excel operations. Affected users cannot copy and paste cells or drag formulas across spreadsheets—core functions essential to daily workflow. Multiple reports confirm that uninstalling or reverting to the previous version immediately restores normal functionality. This suggests the issue stems directly from the update rather than user configuration or third-party conflicts. Microsoft has not yet issued a public statement on the problem or timeline for a fix. Users experiencing disruptions have two options: roll back to the previous version or avoid installing KB5002914 until a corrected patch is available. This is the latest in a series of problematic Microsoft Office updates. The incident highlights risks with mandatory security patches that aren't adequately tested before deployment.
