How to Fix PPTX and DOCX Files Opening Online Instead of in Desktop Apps
Product
Microsoft 365
Device & OS
Windows
Scenario
Double-clicking locally saved .docx and .pptx files on a PC.
Observed behavior
Files are opening in Microsoft 365 for the web via a browser rather than launching in the full offline Microsoft Office desktop applications.
Before you start

Check if you have a paid Microsoft 365 subscription or a licensed desktop version of Microsoft Office installed, as the free Microsoft 365 app from the Microsoft Store only acts as a portal for web applications.

Solution 1Recommended

Install Licensed Desktop Office and Change Default Apps

To open files locally, you must install the full desktop version of Microsoft Office and configure Windows to use it as the default program for your documents.

The free Microsoft 365 application is designed as a web portal and does not include offline desktop applications. To solve this, you need to download the full suite using a valid license and correct your Windows default app settings.

1
Install Desktop Applications

Log into your Microsoft account, verify your active Microsoft 365 subscription, and download the full desktop version of Office. Run the installer and wait for the setup to complete.

2
Open Windows Settings

Press the Windows key + I on your keyboard to launch Windows Settings, then click on the 'Apps' section.

3
Access Default Apps

Navigate to 'Default apps' in the left menu, scroll down to the bottom, and click on the 'Choose default apps by file type' link.

4
Set Default for DOCX and PPTX

Scroll through the list to find the .docx and .pptx file extensions. Click the current default application (which may be set to Microsoft Edge or Microsoft 365) and select the newly installed Word and PowerPoint desktop apps from the list.

Frequently Asked Questions

Why did my new PC come with a Microsoft 365 app that only opens online?

Many new Windows PCs include a free Microsoft 365 application from the Microsoft Store. This app functions merely as a shortcut portal to the web-based versions of Office. It does not contain the actual desktop software, which requires a paid subscription to download and install.

Can I edit DOCX and PPTX files offline without buying Microsoft Office?

Yes. You can install a free desktop office suite like WPS Office. It natively supports Microsoft formats and allows you to create, view, and edit local files offline without needing a paid Microsoft 365 license.

How do I stop my documents from opening in Microsoft Edge?

If you have a desktop office suite installed but files still open in your browser, your file associations are incorrect. Go to Windows Settings > Apps > Default apps > Choose default apps by file type, and change the default program for .docx and .pptx from Microsoft Edge to your preferred desktop application.
