Microsoft confirms October Windows KB5002934 update broke Excel copy paste again, issues fix - Neowin​

Microsoft fixed a recurring Excel copy-paste bug caused by Windows updates by re-releasing an updated KB5002934.

Back in September, Microsoft released the KB5002914 security update for Excel, which broke one of the most basic and used functions in the app, or for that matter, anywhere, copy and pasting. The company later acknowledged the issue and issued a fix with a subsequent update KB5002665.

However, users soon realized that the bug had returned once again in the following October update under KB5002934. To verify their suspicion, affected users uninstalled the update to see if the regression was resolved, and as expected by them, the copy-pasting function soon began working again.

This update was pushed via the Windows update channel which recently published the latest Windows 11 non-security preview releases for the month.

The recurrence of the same bug within a month, especially with something as fundamental as this, is definitely not expected from Microsoft, though it's possible that the tech giant is currently busy with the Windows 11 26H2 rollout that just happened for everyone, as well as its new features like a fully native internet speed monitor that was apparently made in just a "single day in spare time."

On the positive side though, Microsoft acknowledged the issue and has now released a fix for it. The bug affected the Excel 2017 build 16.0.5574.1005 that was initially released by the KB5002934; however, instead of pushing out a new update again via Windows update, the company re-released the same KB5002934 update again, but with a newer build 16.0.5574.1006.

Microsoft has confirmed the copy-paste regression has been resolved by this latest release.

In case you are affected by this issue, you can download the update on Microsoft's official Download Center website at this link. You can check out the official support article for KB5002934 here also on Microsoft's website.
