Reset Microsoft Word to Default Settings on Windows
Source-checked · About 10 minutes
Answer
Rename Word's Normal.dotm template so Word creates a fresh default template, then repair Microsoft 365 only if the problem remains. Renaming preserves a reversible copy of custom styles, macros, and AutoText.
Open Word and create a blank document. Word creates a new Normal.dotm when the original is unavailable.

Test the original symptom
Repeat the broken action and check the default font, margins, styles, or startup behavior before restoring any old customization.
6
Repair Microsoft 365 if needed
If the issue remains, open Settings > Apps > Installed apps, select Microsoft 365 or Office, choose Modify, and start with Quick Repair before Online Repair.
