How to Fix Microsoft 365 Office App Opening to a Blank Screen
Question details
The user needs to resolve an issue where the Microsoft 365 Office app displays a completely blank screen upon launch on Windows 10.
- Product
- Microsoft 365 (Microsoft Store / UWP version)
- Device & OS
- Windows 10
- Scenario
- Launching the Microsoft Office application from the Start menu or desktop, particularly when it has not been used previously.
- Observed behavior
- The application window opens but remains completely blank or white, preventing the user from seeing the interface or accessing any documents.
Before modifying application settings, ensure your Windows 10 system is fully updated and temporarily close any background processes related to Microsoft Office via the Task Manager.
Repair or Reset the Office App in Windows Settings
Use the built-in Windows application management tools to repair or clear corrupted app data that is causing the blank screen to appear.
Windows 10 provides a built-in troubleshooting tool for UWP applications downloaded from the Microsoft Store. Repairing the app fixes missing files without deleting data, while resetting it clears the app's cached configuration.
Click on the Start menu and select the 'Settings' gear icon, or press the Windows key + I on your keyboard.
Click on 'Apps' from the Settings menu, then select 'Apps & features' from the left sidebar.
Scroll down the list of installed programs, locate the 'Office' or 'Microsoft 365' app, click on it, and select 'Advanced options'.
Click the 'Repair' button first. If the app still opens to a blank screen after repairing, return to this menu and click the 'Reset' button to clear the application data.
Uninstall and Reinstall the Office App
If resetting does not work, completely removing the application and downloading a fresh copy from the Microsoft Store can resolve deep software corruption.
Switch to the Click-to-Run Desktop Version
Bypass the Microsoft Store (UWP) app entirely by installing the standard desktop version of Microsoft 365, which is generally more robust and less prone to blank screen glitches.
Experience a Stable and Free Alternative with WPS Office
If the Microsoft Office app continues to show a blank screen or experience glitches, consider switching to WPS Office. It provides a lightweight, highly stable desktop environment without the common UWP app errors, offering a seamless editing experience.
- 1. Download and Install: Visit the official WPS website to download the free, lightweight installer and complete the setup in minutes.
- 2. Open Microsoft Formats: Launch WPS Office and directly open your existing .docx, .xlsx, or .pptx files without any conversion needed.
- 3. Enjoy Stable Editing: Start editing your documents in a stable, crash-free environment that looks and feels just like Microsoft Office.
Frequently Asked Questions
What causes the Microsoft Office app to show a blank screen?
A blank screen is typically caused by corrupted application cache data, an outdated UWP app version, or glitches in the Microsoft Store background services that prevent the app's interface from rendering properly.
Will resetting the Office app delete my documents?
No, resetting the app from Windows Settings only clears the app's temporary data, cached files, and login session. Your personal documents saved locally on your hard drive or in OneDrive will remain completely safe.
What is the difference between the Microsoft Store version and the Click-to-Run version?
The Microsoft Store version is a Universal Windows Platform (UWP) app optimized for basic use and integrated store updates. The Click-to-Run version is the traditional desktop installer, which generally offers greater stability, full features, and is less prone to rendering bugs.
