You can reset Word back to “factory-default” behavior in a few different ways, depending on
what got changed (ribbon, template, add-ins, or Word’s registry settings). Try these in order (least invasive first).
1) Reset only the Ribbon / Quick Access Toolbar (easy)
- Open Word.
- File → Options
- Customize Ribbon (right side) → Reset → Reset all customizations
- Also check Quick Access Toolbar → Reset → Reset only Quick Access Toolbar (or “Reset all customizations”).
This fixes most “I changed the UI and now it’s weird” issues.
2) Start Word in Safe Mode (tests add-ins)
- Press Win + R
- Type:
winword /safe and press Enter
If Word is normal in Safe Mode, an add-in is likely the cause:
- File → Options → Add-ins
- At the bottom, set Manage: COM Add-ins → Go…
- Uncheck add-ins (do them one at a time to find the culprit)
3) Reset Word’s Normal template (common “mystery changes” fix)
Word’s default template is
Normal.dotm. If it’s corrupted or heavily customized, Word can behave oddly.
- Close Word completely
- Press Win + R
- Paste this and press Enter:
%appdata%\Microsoft\Templates
- Find Normal.dotm
- Rename it to:
Normal.old (or Normal.dotm.bak)
- Start Word again (it will recreate a fresh Normal.dotm)
4) Full reset of Word settings (Registry reset)
This resets many Word preferences back to defaults.
Warning: This edits the registry. It’s safe if you follow steps, but do it carefully.
- Close Word
- Press Win + R, type
regedit, press Enter
- Go to (Microsoft 365 / Office 2016/2019/2021 usually use 16.0):
HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Word
- (Office 2013 = 15.0, Office 2010 = 14.0, etc.
- Right-click the “Word” key → Export (backup)
- Then rename these keys if present (or delete them):
Data → (rename to Data.old)
Options → (rename to Options.old)
- Launch Word again
5) Repair Microsoft 365/Office (if Word itself is damaged)
- Settings → Apps → Installed apps
- Find Microsoft 365 (or Office) → Modify
- Run Quick Repair first
- If not fixed, run Online Repair (takes longer, more thorough)
Quick question so I can point you to the right “reset”
What exactly did Word start doing (examples: changed margins/styles, weird font defaults, ribbon missing buttons, Word won’t open, constant freezing, etc.?
Also: you mentioned earlier Opera freezing—if Word is freezing too, that could point to a system-wide issue (GPU driver/add-ins), so tell me whether Word’s issue is
settings/UI or
crashing/freezing.
