Product: Microsoft Word
Device & OS: not provided
Scenario: Attempting to insert an online video into a Word document.

Solution 1Recommended

Start Word in Safe Mode to Identify Add-in Conflicts

Running Word in Safe Mode bypasses third-party add-ins, helping you determine if an incompatible plugin is causing the freeze.

Often, COM add-ins or macros can interfere with Word's built-in dialogs. Safe mode loads Word with a minimal set of features to isolate these variables.

Launch Safe Mode

Press Windows + R on your keyboard to open the Run dialog. Type 'winword /safe' and press Enter.

Test the Online Video Feature

Once Word opens in Safe Mode, attempt to use the Online Video dialog again. If it works without freezing, an add-in is likely the culprit.

Disable Conflicting Add-ins

Go to File > Options > Add-ins. At the bottom, manage COM Add-ins and click Go. Uncheck them one by one to identify which is causing the issue.

Solution 2

Delete Corrupted Normal.dotm Templates

A corrupted default template file can cause interface elements like the Online Video dialog to hang.

Solution 3

Reset the Microsoft Office Word Registry Key

Resetting Word's specific registry keys can resolve deep-seated configuration bugs that prevent dialogs from rendering.

Frequently Asked Questions

Why does Word freeze when inserting an online video?

This is typically caused by conflicting third-party COM add-ins, a corrupted default Word template (Normal.dotm), or misconfigured Word registry settings that fail to load the web-based dialog.

Will deleting Normal.dotm delete my saved documents?

No. Deleting or renaming the Normal.dotm template only resets your default formatting preferences, such as your default font and margin settings. Your saved Word documents will remain completely untouched.

How do I safely back up the registry before resetting Word keys?

Open the Registry Editor, select the specific folder or key you plan to modify, click on 'File' in the top menu, choose 'Export', and save the .reg backup file to a safe location like your Desktop.
