How to Open Files in Office 2019 Instead of Microsoft 365
Question details
The user wants to stop their documents from opening in Microsoft 365 and revert to using Microsoft Office Home and Student 2019 by default.
- Product
- Office Home and Student 2019 / Microsoft 365
- Device & OS
- not provided
- Scenario
- Opening existing Word, Excel, and PowerPoint files directly from the computer.
- Observed behavior
- Files that previously opened in Office 2019 are now automatically launching in Microsoft 365.
Verify that Microsoft Office Home and Student 2019 is actively installed and licensed on your computer by signing into your Microsoft account Services and Subscriptions page.
Change Default Apps by File Type in Operating System
Manually reassign the default application for Office document formats to ensure they open in Office 2019 instead of Microsoft 365.
When multiple versions of Office are installed on the same computer, the operating system can become confused about which application should handle specific file formats. Changing the default apps at the system level resolves this conflict.
Navigate to your computer's system settings and locate the Apps or Applications menu.
Select 'Default apps' and choose the option to 'Choose default apps by file type'.
Scroll down to locate standard Office extensions such as .docx, .xlsx, and .pptx. Click on the current default app (Microsoft 365) and change it to the corresponding Office 2019 application (e.g., Word 2019, Excel 2019).
Check Active Licenses and Installed Versions
Verify your active Office products and force a license update to prioritize Office Home and Student 2019.
Uninstall Microsoft 365 (If Unused)
Remove Microsoft 365 completely if you only intend to use your one-time purchase of Office Home and Student 2019.
Avoid Subscription Hassles with WPS Office
Tired of dealing with conflicting Office versions or forced prompts to use Microsoft 365? WPS Office offers a free, lightweight, and highly compatible alternative that handles all your document needs without the subscription confusion.
- 1. Download WPS Office: Visit the official WPS Office website and download the free installer package for your operating system.
- 2. Install the Software: Run the setup file and follow the on-screen instructions to complete the installation.
- 3. Set as Default Application: Upon launching WPS Office for the first time, allow it to become the default application for opening your documents, spreadsheets, and presentations.
Frequently Asked Questions
Why did my files suddenly start opening in Microsoft 365?
This commonly happens after a major operating system update or when a pre-installed Microsoft 365 trial is activated. The system's file associations are sometimes reset to prioritize the subscription-based Microsoft 365 over standalone versions like Office 2019.
Can I keep both Office 2019 and Microsoft 365 installed on the same computer?
Yes, it is possible to have both installed. However, having multiple versions often leads to file association conflicts where files open in the unintended application. For the best experience, it is usually recommended to only keep the version you actively use.
Will uninstalling Microsoft 365 delete my Word or Excel files?
No. Uninstalling Microsoft 365 only removes the application software itself. Your personal files, documents, and spreadsheets saved on your local drive or cloud storage will remain completely safe and untouched.
How do I check if my Office 2019 license is still active?
You can verify your license by opening any Office 2019 application, clicking on 'File', and selecting 'Account'. Your activation status and product details will be displayed under the Product Information section.
