What “end of support” means
Microsoft describes the consequences for Office 2016 and 2019 as follows; the same principle applies to Office 2021:
- No more security updates. Newly discovered security vulnerabilities are not fixed. This particularly affects opening files from others and email attachments.
- No bug fixes. Bugs in the programs remain.
- No technical support from Microsoft by phone or chat.
- Help pages are no longer maintained, and many are retired.
The programs do not stop working. However, Microsoft points out that performance and reliability may decline over time. Microsoft only supports connecting to the online services of Microsoft 365, such as Exchange Online, as long as an Office version is in mainstream support.
Office and the end of Windows 10
Support for Windows 10 ended on October 14, 2025. According to Microsoft’s system requirements, Office 2024 and Office 2021 require Windows 11. Existing installations on Windows 10 may continue to work, but the operating system itself no longer receives security updates.
A transition period applies to subscribers: on Windows 10, Microsoft 365 still receives security updates until October 10, 2028, but no new features.
What to do now
- Determine the version. In Word, open File › Account. It states which Office version is installed.
- Check the operating system. Office 2024 needs Windows 11 or one of the three most recent versions of macOS.
- Choose the edition. The comparison of the Office 2024 editions shows which edition corresponds to your previous scope.
- Clarify special cases. Convert Publisher files, test add-ins and macros, ask the vendor about approvals for industry software.
- Remove the old version before you install the new one.
What has changed between the two most recent versions is covered in
Office 2024 or Office 2021.
Typical cases
Office with Office 2016 on Windows 10 computers. Two ends of support have coincided here. First bring the computers to Windows 11 or replace them, then install Office 2024.
Office 2019 Home & Business on a new Windows 11 PC. The computer is current, Office is not. Moving to Office Home & Business 2024 restores the same scope.
Office 2021, bought recently. The license remains valid and the programs run. But there are no more security updates. If you open many files from others, you should not put off the switch for long.
