- Device & OS
- Windows
- Scenario
- The user accidentally deleted Microsoft 365 en-US language files, which caused the local desktop suite to break.

Ensure you have the login credentials for the Microsoft account associated with your Microsoft 365 subscription, as you will need them to download the installer.
Reinstall Microsoft 365 from the Official Office Portal
Re-downloading and reinstalling the Microsoft 365 suite is the most effective way to restore missing language files and fix broken file associations.
When critical components like the en-US language files are removed from your system, the Microsoft 365 desktop applications can crash or fail to launch. As a result, Windows defaults to using WordPad to open your documents.
Reinstalling the suite does not require you to manually hunt down missing language packs; the installer will automatically replace the missing core files and re-register your apps with Windows.
Open your web browser, navigate to https://www.office.com, and sign in with the Microsoft account linked to your active subscription.
On your account dashboard, locate and click the 'Install apps' or 'Install Office' button near the top right corner to download the setup file to your computer.
Locate the downloaded file in your Downloads folder, double-click it to run the installer, and follow the on-screen prompts to complete the installation.
Once the installation is finished, restart your Windows computer. Double-click any locally saved Word or Excel document to verify it now opens in the correct application instead of WordPad.

Frequently Asked Questions
Why did my Word documents suddenly start opening in WordPad?
When Microsoft Word becomes unusable—such as when crucial en-US language files are deleted—Windows cannot launch the program. It automatically falls back to WordPad, which is the default, built-in word processor in Windows.
Will reinstalling Microsoft 365 delete my existing Word and Excel files?
No, reinstalling the application only repairs or replaces the software's program files. Your personal documents, spreadsheets, and other local data will remain completely safe on your computer.
Can I just download the missing language pack instead of reinstalling the whole suite?
While you can sometimes download language accessory packs separately from Microsoft, reinstalling the entire Microsoft 365 suite is much more reliable. It ensures that all broken file associations are fixed and all dependent files are properly registered with the operating system.
How do I restore file associations if they still open in WordPad after reinstalling?
If documents still open in WordPad, right-click a document, select 'Open with,' and choose 'Choose another app.' Select Microsoft Word from the list, check the box that says 'Always use this app to open .docx files,' and click OK.
