- Product
- Windows 11 / Microsoft 365
- Device & OS
- Windows 11
- Scenario
- Setting up default applications for document formats in the Windows settings.
- Observed behavior
- The .doc extension does not appear in the Windows 11 Default Apps menu, preventing users from assigning a default application, although Word can still open the file manually via the Open with menu.

Frequently Asked Questions
Why is the .doc extension missing from Windows 11 Default Apps?
This usually happens due to a corrupted Windows registry entry, a conflicting system update, or an incomplete Microsoft 365 installation that failed to properly register legacy file extensions like .doc.
Can I use the 'Open with' menu permanently instead of Windows Settings?
Yes. You can bypass the Default Apps menu by right-clicking the .doc file, selecting 'Open with', choosing your preferred word processor, and checking the 'Always use this app to open .doc files' box to force the association.
Does fixing the Microsoft 365 installation delete my personal documents?
No. Running an Online Repair for Microsoft 365 only replaces and repairs application files and system registry keys. Your personal documents, files, and data will remain completely untouched.
