Frequently Asked Questions

Why do my DOCX files suddenly show a blank icon?

This typically happens when the Windows icon cache becomes corrupted, after a Windows update goes wrong, or if the default application assigned to open DOCX files loses its registry configurations.

Will resetting file associations delete or alter my DOCX documents?

No. Resetting or changing file associations only tells the Windows operating system which program to launch when you double-click the file. Your actual documents and their contents remain completely safe and untouched.

How can I manually refresh the Word registry keys?

Advanced users can re-register Microsoft Word by pressing Windows + R to open the Run dialog, typing 'winword /r', and pressing Enter. This forces Word to rewrite its default settings in the Windows registry.

Does running an Office repair delete my custom settings?

Running a 'Quick Repair' generally preserves your personal settings and documents. An 'Online Repair' is a more thorough reinstallation and may reset some application preferences, but your saved DOCX files will not be affected.
