We have the same situation on Office LTSC Standard 2021, and we can't downgrade with clicktorun.

Do you have a patch for this version?

It cannot be uninstalled because there is no uninstall button.

@Suradej

Which specific update are you referring to? For example, the KB article at https://support.microsoft.com/en-us/servicing/office/hotfix/excel/5002914 discusses an update intended for classic MSI installations. Most recent Office installations are using click-to-run (virtualization) technology instead.

It cannot be uninstalled because there is no uninstall button.

If you are indeed referring to an update for the operating system (as opposed to an update for Office), see https://support.microsoft.com/en-us/windows/deployment/updates-lifecycle/how-to-uninstall-a-windows-update .

I'm having the same problem with copy-and-paste, as well as issues with cells shifting (Office 16 - Windows 11 64-bit)

I’m facing the same issue. Even after removing the patch, the same problem recurs the next day. How can I fix this?

Why Microsoft still pushing this update?

That is a fair question. The KB article does say that the issue is being investigated, so I'm assuming that Microsoft intends to fix the issue. See https://support.microsoft.com/en-us/servicing/office/hotfix/excel/5002914 .

Just to follow up -

Microsoft has released a corrective update.

For Excel 2016, KB5002665, released September 16, 2026, specifically fixes the known KB5002914 issue that caused certain paste operations to fail silently.

https://support.microsoft.com/en-us/servicing/office/hotfix/excel/5002665

One caveat: Microsoft says paste operations may still fail in workbooks containing conditional formatting. So this is a confirmed fix for the original issue, but not yet a complete resolution of every paste failure scenario.
