- Product
- Microsoft 365 Word
- Device & OS
- Windows
- Scenario
- Attempting to launch Microsoft Word on a refurbished or existing Windows laptop for document editing.
- Observed behavior

Ensure your laptop is connected to a stable internet connection and back up any unsaved work in other Microsoft 365 applications before starting the update or reinstall process.
Update Microsoft 365 and Windows OS
Keeping your Office applications and Windows operating system up to date resolves most app launch failures caused by software conflicts or outdated files.
Microsoft frequently releases updates to fix known bugs and improve compatibility. Triggering an update from another working Office app can often resolve the issue with Word.
Open another working Microsoft 365 application, such as Excel or PowerPoint. Click on 'File' in the top-left corner, and then select 'Account' from the left sidebar.
Under the Product Information section, click on 'Update Options' and select 'Update Now' from the drop-down menu. Allow Microsoft 365 to check for and install the latest versions.
Open Windows Settings by pressing Win + I. Go to 'Update & Security' > 'Windows Update', and click 'Check for updates'. Install any pending updates and restart your computer.
Uninstall and Reinstall Microsoft 365
If updating doesn't work, the core installation files might be heavily damaged. A clean reinstall will restore the necessary components for Word to run.

Frequently Asked Questions
Why is Microsoft Word suddenly not opening on my Windows laptop?
Word can fail to open due to several reasons, including corrupt third-party add-ins, outdated Office versions, pending Windows system updates, or a corrupted user profile on your device.
Can I still open my Word documents if Microsoft 365 won't launch?
Yes. You can upload the document to OneDrive to view and edit it in Word for the Web. Alternatively, you can install a free office suite like WPS Office to open and edit your local .docx files without needing Microsoft 365.
Does repairing Microsoft Office fix Word launch issues?
Often, yes. You can go to Windows Settings > Apps, locate Microsoft 365, select 'Modify', and choose either 'Quick Repair' or 'Online Repair' to automatically fix damaged installation files.
How do I start Word in Safe Mode to check for add-in conflicts?
Press the Windows key + R to open the Run dialog box, type 'winword /safe', and hit Enter. If Word opens successfully in Safe Mode, a recently installed add-in is likely causing the launch failure.
