Solution 1Recommended

Verify File Extension and Reassociate with Word

Turn on file extensions in Windows to ensure the document is a true .docx file, then manually set Microsoft Word as the default application.

Sometimes files lose their proper extension when downloaded or transferred, confusing Windows about which application to use. Verifying the extension and manually reassociating it is the most direct fix.

1
Enable File Extensions

Open File Explorer, navigate to the 'View' tab at the top of the window, and check the box for 'File name extensions'. In Windows 11, click 'View' > 'Show' > 'File name extensions'.

2
Verify the Extension

Locate your problematic document. Ensure the file name ends in '.docx'. If it doesn't, right-click the file, select 'Rename', and add '.docx' to the end.

3
Choose Default App

Right-click the '.docx' file and select 'Open with'. If Word is not listed, click 'Choose another app'.

4
Select Microsoft Word

Scroll through the list of applications. If needed, click 'More apps'. Once you find Microsoft Word, select it, check the box that says 'Always use this app to open .docx files', and click 'OK'.

Verify File Extension and Reassociate with Word
File Association Restored: Once completed, all .docx files on your computer will automatically open with Microsoft Word when double-clicked.

Frequently Asked Questions

Why did Microsoft Word suddenly disappear from my 'Open with' list?

This typically happens after a major Windows update, an interrupted Microsoft Office update, or if the registry keys managing file associations become corrupted. Running an Online Repair for Office usually resolves this issue by restoring the missing registry keys.

How do I manually browse for Microsoft Word if it's not in the 'More apps' list?

When prompted to choose an app, click 'More apps', scroll to the bottom, and click 'Look for another app on this PC'. Navigate to 'C:\Program Files\Microsoft Office\root\Office16' (this path may vary slightly by version) and select the 'WINWORD.EXE' application file.

Will renaming the file extension to .docx damage my document?

Renaming a file to add or fix the .docx extension will not damage the contents, provided the file was originally created as a Word document. However, changing it to an unrelated extension (like .jpg or .mp3) will make it unreadable until you change it back to .docx.

Can I use another program to open my Word document if my Microsoft Office subscription is expired?

Yes, you can use free office suites like WPS Office to open, edit, and save .docx files seamlessly. WPS Office provides native support for Word documents without requiring an active Microsoft 365 subscription.
