Solution 1Recommended

Perform an Office Quick Repair

Running a Quick Repair can fix damaged Office installation files and restore the correct file associations required to open Word documents.

The Windows 11 upgrade process can occasionally disrupt application settings. The built-in repair tool for Microsoft Office is the safest and most effective way to resolve these inconsistencies without losing personal data.

Open Windows Settings

Press the Windows key + I to open Settings, navigate to 'Apps' on the left sidebar, and select 'Installed apps'.

Locate Microsoft Office

Scroll through the application list or use the search bar to find your installation of Microsoft Office or Microsoft 365.

Select the Modify Option

Click the three horizontal dots next to the Office application and choose 'Modify' from the drop-down menu.

Run Quick Repair

Select 'Quick Repair' from the prompt that appears and click the 'Repair' button. Wait for the process to complete, then attempt to open your Word document.

Administrator Privileges: You may be prompted by User Account Control (UAC) to allow the app to make changes to your device. Click 'Yes' to proceed with the repair.

Frequently Asked Questions

Why did my Word documents stop opening after installing Windows 11?

Operating system upgrades can sometimes reset default app settings, alter file associations, or temporarily misconfigure registry keys, preventing Windows from knowing which program should open your document files.

Will I lose my Word files if I run an Office repair?

No. Your personal Word documents are saved independently from the application files. Running a Quick Repair or reinstalling Microsoft Office will not delete or alter your .doc or .docx files.

How can I tell if I'm using Word desktop or Word for the Web?

Word for the Web runs entirely inside a web browser (such as Edge or Chrome) and requires an internet connection to access. The desktop version is a dedicated application installed directly onto your PC.
