- Product

- Device & OS
- Windows
- Scenario
- Converting PDFs to Word documents or attempting to open existing DOCX files from the file explorer.
- Observed behavior

Restore Word as the Default App for DOCX Files
Use this method if your DOCX files are accidentally opening in a PDF reader instead of your word processor.
This issue frequently occurs when a newly installed PDF reader inadvertently takes over the default file association for Word documents.
Find any DOCX file on your Windows computer and right-click on it to open the context menu.
Hover over 'Open with' in the context menu, then click on 'Choose another app' from the extended list.
Choose 'Microsoft Word' (or your preferred document editor) from the list of available applications.
Check the box at the bottom labeled 'Always use this app to open .docx files', then click 'OK' to save the changes.

Troubleshoot Conversion Errors via Customer Support
If your PDF still fails to convert correctly, the source file may be encrypted, corrupted, or require advanced technical support.

Frequently Asked Questions
Why are my Word documents suddenly opening as PDFs?
This typically happens if a PDF reader was recently installed or updated, which accidentally reassigned the default file association for .docx files. You can fix this by right-clicking a document, selecting 'Open with', and choosing your word processor as the permanent default app.
Can I convert a scanned PDF to an editable Word document?
Yes, but it requires an Optical Character Recognition (OCR) feature. Basic PDF readers cannot extract text from images, but advanced suites like WPS Office have built-in OCR tools to turn scanned PDFs into editable DOCX files.
What should I do if a converted DOCX file loses its original formatting?
Complex PDFs with intricate layouts, non-standard fonts, or layered images might lose formatting during conversion. To prevent this, use a dedicated PDF converter with high-fidelity formatting retention, or manually adjust the layout in your word processor post-conversion.
How do I ensure Word is the default app for all document types in Windows?
Navigate to Windows Settings > Apps > Default apps. Scroll down to 'Choose default apps by file type', locate formats like .doc and .docx, and explicitly select your preferred word processor for each format.
