Question details

Users are experiencing an issue where their Microsoft Word documents (.docx) are opening in WordPad rather than the intended Microsoft Word application.

Product: Microsoft Word
Device & OS: not provided
Scenario: Attempting to open DOCX files from the file explorer.
Observed behavior: The DOCX file opens in WordPad as an Office Open XML document file instead of Microsoft Word, indicating a broken file association or unregistered Office installation.

Before you start

Verify that Microsoft Word is still actively installed on your computer, as Windows may default to WordPad if your Office subscription has expired or the software was accidentally uninstalled.

Solution 1Recommended

Run a Quick Repair for Microsoft Office

Repairing the Office installation resolves broken file registry settings that cause documents to open in WordPad.

Windows uses registry keys to determine which application opens specific file types. If Microsoft Word is not registered correctly, running a Quick Repair will scan and fix these broken associations automatically.

Open Windows Settings

Press the Windows key, type 'Control Panel' or 'Settings', and navigate to the 'Apps' or 'Programs and Features' section.

Locate Microsoft Office

Scroll through the list of installed applications until you find your version of Microsoft Office or Microsoft 365, then select it.

Run the Repair Tool

Click 'Modify' or 'Change', select the 'Quick Repair' option in the prompt that appears, and click 'Repair' to begin the process.

Online Repair Option: If the Quick Repair does not solve the issue, you can repeat the steps and choose 'Online Repair' for a more comprehensive fix, though this will require an internet connection and take longer.

Solution 2

Restore Microsoft Word as the Default Application

Manually reassigning the DOCX file extension to Microsoft Word ensures files open in the correct program.

Frequently Asked Questions

Why did my DOCX files suddenly start opening in WordPad?

This typically happens when the Windows file association registry for DOCX files becomes corrupted, Windows updates reset default app preferences, or if your Microsoft Office installation was recently modified or uninstalled.

Will repairing Microsoft Office delete my personal Word documents?

No, running a Quick Repair or Online Repair only fixes the software's program files and registry keys. Your personal DOCX documents remain completely safe and untouched during the repair process.

Why do my Word documents look different and lose formatting in WordPad?

WordPad is a basic text editor included with Windows and does not support the complex formatting, styles, margins, and features of Microsoft Word DOCX files, which causes the document's layout to break.
