How to make Office 2016 or 2019 or 365 your default Microsoft Office application?

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?”

Set Office 365 / 2019 /2021 as default

If you are using Office 365 on your Windows 10 computer, you can define it as the default version as following:

  • Hit the Windows button at the left hand side of your taskbar.

  • Then select Programs.
  • Then Select Programs and Features.
  • Then go ahead and highlight the Microsoft 365 entry as shown below.
  • Now hit Change.

  • 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.

Additional notes:

  • There might be cases, mainly around compatibility with older file formats, in which you might want to leaver the older Office versions (2010 and older) as default.
  • 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.

  1. I have been frustrated by the issue of Windows 10 not offering the option of selecting a desktop application for setting the default program when you are trying to do this through Default app settings > Set defaults by app > Excel 2016 > Manage. Using this standard approach, only the “Look for an app in the Store” is shown (i.e. it is not possible to choose a desktop app) – I am using the desktop apps of Office 365. This was so easy to do in earlier versions of Windows (through Control Panel).

    The fix described here is simple and it works (luckily, Microsoft has not been successful with clobbering Windows/File Explorer, as it was with switching everything away from the powerful Control Panel to the dumb Settings app). Thank you for taking the time to post this!

  2. to make office 365 your default. you must log into office 365 via your web browser then make that browser your default program for opening Microsoft docs and excels files.
