Short answer: Office 2016, 2019, 2021, and 2024 all run on Windows 11. However, only Office 2021 and 2024 still receive security updates – therefore, only these two are suitable for new installations.
Which Office versions are compatible with Windows 11?
| Version | Runs on Windows 11 | Security updates |
|---|---|---|
| Office 2016 | yes | no (since Oct. 2025) |
| Office 2019 | yes | no (since Oct. 2025) |
| Office 2021 | yes | until Oct. 2026 |
| Office 2024 | yes | until Oct. 2029 |
Why "runs" does not equal "recommended"
Just because Office 2016 starts on Windows 11 doesn't mean it's sensible to use. Without security updates, known vulnerabilities remain permanently open – and Office documents are a popular attack vector.
System requirements for Office 2024
- Windows 11 or Windows 10 in a supported version
- At least 4 GB RAM
- 4 GB free disk space
- Internet connection for installation and activation
What to do when changing computers?
If you are moving from Windows 10 to a new Windows 11 computer, Office can often be transferred – depending on the license type. OEM licenses remain tied to the original hardware, while volume and retail licenses can usually be transferred, provided the old installation is removed.
"I thought, the main thing is that Office runs – until our system house found out during a routine check that half of our computers still had unpatched Office 2016 installations." This is how a small business owner describes why he consistently opted for Office 2024 during his next computer change – not just because it ran, but because it was secure.
Recommendation
For a new installation on Windows 11, Office 2024 is the obvious choice – five years of security updates and the current interface. If you want to save money and can live with a shorter support period, choose Office 2021.
