Repair Microsoft Office via Apps and Features
Using the built-in Windows Quick Repair tool can resolve corrupted Office files or glitches that cause the sign-in window to crash.
This method addresses underlying application file corruption without deleting your personal documents or removing the software completely.
Reboot your system to ensure no background Microsoft Office processes are stuck or interfering with the repair.
Right-click the Windows Start menu and select 'Apps and Features' (or 'Installed apps' depending on your Windows version).
Scroll through your installed programs to locate your Microsoft Office suite, click on it, and select 'Modify'.
Choose the 'Quick Repair' option from the prompt and follow the on-screen instructions to fix the application.
Once the repair finishes, launch Word, Excel, or PowerPoint and attempt to sign in again to see if the window stays open.
Switch to WPS Office for a Hassle-Free Experience
If Microsoft Office continues to experience sign-in glitches or crashes, consider switching to WPS Office. It is a free, lightweight, and highly compatible alternative that lets you open, edit, and save Word, Excel, and PowerPoint files without complex login hurdles.
- 1. Download the Installer: Visit the official WPS Office website and click the free download button.
- 2. Install WPS Office: Run the downloaded installer file and follow the quick setup instructions.
- 3. Start Editing: Open the application and immediately start editing your documents without worrying about forced sign-in interruptions.
Frequently Asked Questions
Why does my Office sign-in screen disappear?
This usually happens due to corrupted Office installation files, conflicting background processes, or issues with your Windows user account credentials interacting improperly with the authentication service.
Will running Quick Repair delete my Microsoft Office files?
No, Quick Repair only scans and replaces corrupted program files. It does not delete your personal documents, templates, or customized settings.
What should I do if Quick Repair doesn't fix the sign-in issue?
If Quick Repair fails, you can try selecting 'Online Repair' from the same Modify menu, which performs a more thorough fix by downloading fresh files from Microsoft's servers.
Can a network issue cause the sign-in window to close?
Yes, an unstable internet connection or strict firewall settings can interrupt the authentication process, causing the prompt to time out and close unexpectedly.
