Fix Excel and Word Crashing After Windows 11 or McAfee Update
Question details
The user needs to resolve persistent crashes in Microsoft Excel, Word, and PowerPoint that started occurring after a Windows 11 upgrade and a McAfee update.

- Product
- Microsoft Office
- Device & OS
- Windows 11
- Scenario
- Opening and using Office applications following recent operating system or third-party security software updates.
- Observed behavior
- Office applications repeatedly report a problem and force close. Standard repairs fail, reinstallations trigger error code 30015-11 (3221549173), and the user encounters repeated Windows Security and d.docs.live.net sign-in prompts.
Before troubleshooting, ensure you have your Microsoft account credentials readily available, as you may need to sign in again after reinstalling Office or clearing cached credentials.
Update and Configure McAfee Security Software
McAfee updates can sometimes conflict with Office applications. Ensuring it is fully updated or adjusting its settings can identify and resolve the conflict.
Third-party antivirus programs frequently monitor application behavior. An outdated security definition might falsely identify newly updated Windows 11 or Office processes as threats, causing the apps to close unexpectedly.
Open McAfee from your system tray, navigate to settings, and manually check for the latest software and virus definition updates.
Turn off the real-time scanning feature temporarily to test if Word and Excel open without crashing.
If the apps work with the scanner disabled, add the Microsoft Office executables (such as WINWORD.EXE and EXCEL.EXE) to McAfee's exclusion or whitelist settings.

Use the Microsoft Support and Recovery Assistant (SaRA)
When standard uninstallation fails or yields error 30015-11, the official removal tool is required to completely clear corrupted Office registry keys and files.
Clear Windows Credentials to Fix Sign-in Prompts
Authentication loops related to d.docs.live.net or Windows Security can cause Office apps to freeze or crash upon opening.
Switch to WPS Office for a Stable, Crash-Free Experience
If Microsoft Office continues to crash on Windows 11 despite your best troubleshooting efforts, try WPS Office. It is a highly compatible, lightweight, and free alternative that works seamlessly on modern Windows systems without causing complex registry or security conflicts.

Frequently Asked Questions
Why is Microsoft Office suddenly crashing after a Windows 11 update?
Windows updates can sometimes alter system files, permissions, or drivers that Microsoft Office relies on. They can also introduce temporary incompatibilities with third-party antivirus software like McAfee, causing Office processes to be blocked and forcefully closed.
What does Office installation error code 30015-11 mean?
Error code 30015-11 typically indicates a failure to write to the Windows registry or a conflict with corrupted existing Office files. It often requires using the official Microsoft Support and Recovery Assistant (SaRA) to completely clean the system before attempting to reinstall.
How do I stop the d.docs.live.net sign-in prompt in Word?
This prompt occurs when Office struggles to authenticate your OneDrive connection. You can resolve it by opening the Windows Credential Manager, deleting any cached credentials related to Microsoft Office or d.docs.live.net, and signing back in through the application.
