Completely Remove and Reinstall Microsoft Office
Use Microsoft's official uninstallation tool to clear deeply rooted corrupted files that prevent Word and Excel from starting, then install a fresh copy.
Standard uninstallation from the Control Panel often leaves behind residual configuration files or corrupted registry entries. Using the dedicated uninstall support tool ensures a completely clean slate before reinstalling the software.
Download and run the official Microsoft Office uninstall support tool from the Microsoft Support website.
Follow the on-screen prompts in the tool to completely remove all Microsoft Office applications and residual files from your computer.
Restart your computer once the uninstallation process is fully complete to clear the system memory.
Go to https://www.office.com/myaccount, sign in with your licensed Microsoft account, and click 'Install' to download the setup file.
Run the downloaded setup file and follow the installation wizard to freshly install Word, Excel, and other Office apps.

Escalate to Microsoft Technical Support
If reinstalling does not resolve the startup failures, gather specific system details and contact Microsoft Support for advanced diagnostics.

Frequently Asked Questions
Why won't Word and Excel open after updating Windows or Office?
System or software updates can occasionally corrupt Office installation files or create conflicts with existing COM add-ins. Running a complete reinstallation using the official Microsoft uninstall tool usually resolves these conflicts.
How can I find the exact error message when Office fails to start silently?
If Word or Excel crashes without displaying an error, you can open the Windows 'Event Viewer', navigate to 'Windows Logs' > 'Application', and look for error events flagged with a red icon that correspond to the time you tried to launch the app.
Will I lose my documents if I completely uninstall Microsoft Office?
No, uninstalling the Microsoft Office applications does not delete your personal files. Your Word documents (.docx) and Excel spreadsheets (.xlsx) will remain safely stored on your hard drive and can be opened once the software is reinstalled or by using an alternative like WPS Office.
How do I verify that my Microsoft Office license is active?
Navigate to office.com and log in with your Microsoft account credentials. Click on your profile and check the 'Services & subscriptions' section to confirm that your account holds an active license before you uninstall the software.
