Fix Microsoft 365 Update Stuck and Office Apps Not Opening
Question details
Microsoft 365 remains indefinitely stuck in an updating state, preventing users from opening or using any Office applications.
- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- The user is attempting to launch an Office application like Word or Excel, but is blocked because an automatic update is frozen.
- Observed behavior
- The update process hangs without completion, and Office applications refuse to launch, completely halting productivity.
Verify that your internet connection is stable, and make sure to save any unsynchronized work or documents to a local drive before attempting repairs.
Start Office Applications in Safe Mode
Use this method to bypass add-ins and startup programs that might be conflicting with the update process.
Opening an Office application in Safe Mode allows it to start without loading certain add-ins or extensions. If the application opens successfully in Safe Mode, a third-party add-in is likely causing the update to hang.
Press the Windows key + R simultaneously on your keyboard to open the Run command window.
Type 'winword /safe' (for Word) or 'excel /safe' (for Excel) into the text box and press Enter.
If the application launches, navigate to File > Options > Add-ins to disable active add-ins and restart the application normally.
Run the Microsoft Office Online Repair Tool
This is the most effective way to fix corrupted installation files or frozen update processes.
Use Microsoft Support and Recovery Assistant (SaRA)
Use this advanced tool if the standard Online Repair fails to fix the stuck update.
Switch to WPS Office When Microsoft 365 Won't Open
If Microsoft 365 updates continue to freeze and interrupt your workflow, consider using WPS Office. It is a lightweight, reliable suite that doesn't suffer from heavy background update crashes, ensuring you can always access and edit your important documents.
- 1. Download and Install: Get the free installation package from the official WPS website and install it in seconds.
- 2. Launch the Software: Open WPS Office and navigate to the Home screen.
- 3. Open Your Files: Click 'Open' and select your Microsoft Office documents to instantly resume your work.
Frequently Asked Questions
Why is my Microsoft 365 update stuck for hours?
Updates can get stuck due to network interruptions, conflicts with third-party antivirus software, or corrupted local installation files. Running the Online Repair tool is usually the quickest way to resolve this.
Will I lose my documents if I uninstall and reinstall Microsoft 365?
No, uninstalling the Microsoft 365 applications does not delete your personal files, such as Word documents or Excel spreadsheets. However, it is a good practice to ensure all current work is saved and synced before starting the uninstallation process.
How do I bypass the update and force Word to open?
You can attempt to bypass the update lock by opening the application in Safe Mode. Hold down the CTRL key while clicking the Word shortcut, or press Win+R and run 'winword /safe'.
