Solution 1Recommended

Restart Your Computer to Clear Frozen Processes

Use this solution first. A system restart clears any background Windows Installer processes that may be causing the repair to hang.

Often, a Microsoft 365 Quick Repair gets stuck because a background service or another software installation is silently running or has frozen. Restarting your machine terminates these locked processes.

1
Restart Windows

Click the Windows Start button, select the Power icon, and click Restart. This will force close any stuck installation instances.

2
Verify Application Functionality

Once your computer reboots, try launching a Microsoft 365 application like Word or Excel. The Quick Repair might have actually finished before freezing, and the apps may open normally.

Frequently Asked Questions

What is the difference between Microsoft Quick Repair and Online Repair?

Quick Repair runs fast (usually under 10 minutes) and works offline by fixing or replacing corrupted files using data already on your hard drive. Online Repair takes much longer and requires an active internet connection because it completely uninstalls the suite and downloads fresh installation files from Microsoft.

Why does Windows say 'another change is in progress' during repair?

This error message appears when the Windows Installer service is currently being used by another program's installation or update process in the background. If the process is frozen, a simple computer restart will clear the service and allow the Microsoft 365 repair to continue.

Will running Microsoft 365 repair delete my personal documents?

No. Running either a Quick Repair or an Online Repair will only target the application files (like Word, Excel, and PowerPoint executable files). Your personal files, documents, and spreadsheets remain completely safe on your computer's storage.
