If Word starts changing margins, fonts, or other defaults on its own, the most direct fix is to reset the template that stores those defaults. In Word, that file is Normal.dotm.
Reset Word by rebuilding the Normal.dotm template and, if needed, refreshing Office registry settings.
Start with the template reset because it is the safer option. If Word still behaves unpredictably after that, you can also refresh Word-related settings in the Windows registry.
Reset the Normal.dotm template
This is the main reset method because Word stores default formatting choices such as fonts and margins in Normal.dotm.
Close Word and open the Templates folder
Exit Microsoft Word completely. Then open the Run dialog box and enter:
This path opens the folder that contains Word’s default template file.
Rename Normal.dotm instead of deleting it
Find Normal.dotm in that folder. Rename it, or move it to another folder as a backup, rather than deleting it.
When you reopen Word, the program should automatically create a fresh default copy. That is the expected result if the reset worked.
How to verify the reset
- Open Word again after renaming Normal.dotm.
- Create a blank document and check whether margins, fonts, and other defaults stop changing unexpectedly.
- If Word behaves normally, the new template has replaced the old default settings.
Reset Word-related registry settings
Use this second method only if the template reset does not fully solve the problem.
Open Registry Editor and go to the Office key
Press the Windows key, search for Registry Editor, and open it. Then paste this path into the address bar:
This location stores Office preferences for the current Windows user profile.
Rename the Office folder and restart Word
Rename the Office folder to Officeold. Then start Word again.
Office should generate a new profile with default settings. If Word opens with stable defaults, the registry refresh has taken effect.
What each reset changes
| Method | Exact location | Action | Expected result |
|---|---|---|---|
| Template reset | %appdata%\Microsoft\Templates | Rename or move Normal.dotm | Word creates a new default template |
| Registry reset | Computer\HKEY_CURRENT_USER\Software\Microsoft\Office | Rename Office to Officeold | Office creates a new user profile |
Important note before resetting
Keep a backup of your template
Renaming Normal.dotm is preferred over deleting it because you can restore it later if you need your old custom settings back.
Registry changes affect Office behavior
The registry method resets Office preferences for the current user. Use it carefully and only after the template method if Word still does not return to normal behavior.
What this reset can fix
Unexpected changes to margins, fonts, and other default formatting choices stored in Word’s template or profile.
What it does not guarantee
no documented behavior establishes a one-click reset button inside Word. The supported methods here are template and registry resets.
Rename Normal.dotm first, reopen Word, verify the result, and use the registry method only if the issue continues.
Reset Word safely by rebuilding its template first
The clearest fix is to rename Normal.dotm so Word creates a fresh default template. If that does not stop the random formatting changes, rename the current-user Office registry key so Office can rebuild its profile.

Reset Microsoft Word to Its Default Settings FAQs
How can I tell whether Word created a new default template?
After reopening Word, return to %appdata%\Microsoft\Templates and check whether a new Normal.dotm file appears. That confirms Word rebuilt the template.
When should I use the registry reset instead of the template reset?
Use the registry reset only if renaming Normal.dotm does not stop the unexpected behavior. It targets Word and Office preferences stored under your current Windows user profile.
Can I restore my previous Word setup after resetting it?
Yes. If you renamed rather than deleted the file or registry key, you can close Word and restore the original Normal.dotm or rename Officeold back to Office .
How can I tell whether Normal.dotm was the real cause?
Reopen Word after renaming the file and create a blank document. If margins, fonts, and other defaults stop changing randomly, the old Normal.dotm was likely causing the problem.
