Repair Apps Using Windows 11 Settings

Use the built-in Advanced Options in Windows 11 Settings to repair broken Microsoft apps without losing your personal data.

Windows 11 includes a dedicated repair tool for installed applications. This feature scans the core app files for corruption and replaces damaged components while preserving your saved documents and preferences.

Open Windows Settings

Click the Start button and select the Settings gear icon, or press the Windows key + I on your keyboard to instantly open the Settings menu.

Navigate to Installed Apps

In the left-hand sidebar, click on 'Apps', then select 'Installed apps' from the list of options on the right.

Access Advanced Options

Scroll down or use the search box to find 'Microsoft Edge' or the specific 'Microsoft 365' app causing trouble. Click the three horizontal dots (...) next to the app name and select 'Advanced options'.

Run the Repair Tool

Scroll down to the Reset section and click the 'Repair' button. A checkmark will appear next to the button once the process completes successfully.

Restart and Test

Repeat this process for any other affected Microsoft 365 or Store applications. Once finished, restart your computer and try opening the apps again to verify they are working normally.

Options Relocated: If you cannot find the Advanced options immediately, use the search bar at the top of the Settings window to search for 'Repair apps' or the specific app name, as Windows updates may occasionally change menu layouts.

Frequently Asked Questions

Why did my Microsoft 365 apps suddenly stop working on Windows 11?

This issue is typically caused by corrupted system files, an interrupted background update, conflicts with Microsoft Edge Webview2 components, or corrupted caches inside the Microsoft Store.

Will repairing Microsoft 365 apps delete my saved documents and files?

No. Using the 'Repair' function in Windows Settings only scans and fixes the application's core files and registry entries. It is completely safe and does not delete your personal files, documents, or custom settings.

What should I do if the 'Repair' button is missing or grayed out?

If the 'Repair' option is unavailable under Advanced options, go back to the 'Installed apps' list, click the three dots next to the app, and select 'Modify'. This will often launch the official Office installer prompt where you can select 'Quick Repair' or 'Online Repair'.
