Applicable to the following Office versions: 2019, 2016, 2013, 365; on Windows 7, 8 and Windows 10.
Here’s a question we received from one of our readers:
“I’ve just installed a new version of Office 365 in my system but it’s clearly not defined as the default program for viewing and editing of Microsoft Office files. After the installation, all my documents, workbooks and presentations are showing up in the Windows File Explorer as unknown file types. Can you help me to define Office 365 as the default file opener for Word, Excel, PowerPoint and Visio files over older Office versions?”
Thanks for the question. In this post we will learn how to set your new Office version (be it 2016, 365 or 2019) as default for the Microsoft Office files types you just mentioned above.
Office 2016 as default program instead of older versions
Windows allows us to associate the newer Office version to all relevant files by executing a Quick Repair action from the Control panel. Steps are described below:
- Open the Control Panel in your system and click Programs and Features.
- Search and check on Microsoft Office 2016.
- Click on it and hit Change present at the top.
- Check on Quick repair to fix the issues and select Repair.
Office 365 / 2019 /2021 as default
If you are using Office 365 on your Windows 10 computer, proceed as following:
- Hit the Windows button at the left hand side of your taskbar.
- Type Control Panel and hit Enter.
- Then select Programs.
- Then Select Programs and Features.
- Then go ahead and highlight the Microsoft 365 entry as shown below.
- Now hit Change.
- Then hit Repair.
- Wait that the repair process is over, your files should now be opening with Office 365 by default.
Additional Option: Setting defaults in Windows 10
Note: You can execute the steps above in Windows 10 using the Default apps screen. Here’s how you do it:
- Hit the Search Windows magnifying glass icon (located at the left hand side of your task bar).
- In the search box, type ‘Default’; and select Choose a default app…
- Then for each known/relevant file type, select the default opening app.
If all the above mentioned techniques didn’t help, you might need to try the manual method specified below.

- There might be cases in which Word, PowerPoint or Excel 2016, will not be listed in the default program list. If that’s the case immediately after you have installed the new version, you might want to restart your computer and re-check. If there is still an issue, you might need to re-run the installation program.
- Compatibility issues might arise when trying to open Microsoft Office files in Open Office, Libre and Google Docs.
