Device & OS

Scenario
The user regularly works with large Word documents of several hundred pages and needs them to remain responsive after an Office update.

Solution 1Recommended

Run Microsoft Word in Safe Mode to Check Add-ins

Use this first when a large document freezes after an Office update, because Safe Mode disables add-ins and templates that often cause Not Responding.

Safe Mode loads Word without COM add-ins, templates, and customizations. If the document opens normally in Safe Mode, an add-in or template is likely causing the freeze.

1
Open Run dialog

Press Windows + R, type winword /safe, and then press Enter to launch Word in Safe Mode.

2
Open a copy of the large document

In Safe Mode, go to File > Open, select a copy of the affected document, and check whether it remains responsive.

3
Disable suspicious add-ins

Click File > Options > Add-ins, select COM Add-ins from the Manage list, click Go, and clear add-ins that are not required.

4
Restart Word normally

Close Safe Mode, open Word normally, and reopen the document to confirm whether the freezing is resolved.

Run Microsoft Word in Safe Mode to Check Add-ins
Add-in identified: If the document stays responsive after disabling add-ins, re-enable them one at a time to find the exact cause.

Frequently Asked Questions

Why does Word only freeze on one large document and not on smaller files?

Large documents often contain more graphics, tables, fields, or imported content, and an Office update can change how Word handles those elements. Test the file in Safe Mode and split it into smaller documents to isolate the problem.

How do I start Microsoft Word in Safe Mode?

Press Windows + R, type winword /safe, and press Enter. Word opens without add-ins and custom templates, which helps you test whether an add-in is causing the Not Responding state.

Will repairing Microsoft Office delete my Word documents?

No. Quick Repair and Online Repair affect Office program files, not your personal documents. Still, close the affected document and keep a copy before running a repair.

Can WPS Office open a large Word file that freezes in Microsoft Word?

Yes. WPS Office Writer can open .doc and .docx files, and many users find it handles large documents more smoothly on the same Windows PC. Open the file, then save a fresh copy to continue working.
