Test in Safe Mode and Roll Back the Office Update

Since this issue is linked specifically to Office update 2302, verifying the issue in Safe Mode and then temporarily reverting to a previous Office build is the most effective workaround.

Running Word in Safe Mode helps ensure that no third-party add-ins are interfering with file loading. If the HTML file still fails to open, reverting Microsoft Office to a previously stable version will bypass the bug introduced in build 16130.

1
Launch Word in Safe Mode

Press the 'Windows key + R' to open the Run dialog. Type 'winword /safe' and press Enter. Try opening the large HTML file. If it still freezes, proceed to roll back the update.

2
Disable Automatic Office Updates

Open a blank document in Word. Navigate to 'File' > 'Account' (or 'Office Account'). Click on 'Update Options' and select 'Disable Updates' from the drop-down menu to prevent Office from immediately reinstalling the buggy version.

3
Revert Office to an Earlier Build

Click the Start menu, type 'cmd', right-click 'Command Prompt', and select 'Run as administrator'. Type 'cd %programfiles%\Common Files\Microsoft Shared\ClickToRun' and press Enter. Then, type 'officec2rclient.exe /update user updatetoversion=16.0.16026.20200' (or another known stable build number) and press Enter to start the rollback process.

Test in Safe Mode and Roll Back the Office Update
Security Updates: Rolling back updates temporarily removes recent security patches. Monitor Microsoft's release notes and re-enable automatic updates once a fix for the HTML rendering bug is confirmed in a newer build.

Frequently Asked Questions

Why does Word freeze when opening large HTML files?

Microsoft Word's HTML parsing engine can occasionally struggle with complex coding or large file sizes. Specifically, Office update version 2302 (build 16130) introduced a known bug that causes the application to stop responding or loop its loading bar when opening HTML documents larger than 1 MB.

How do I check my current Microsoft Office version and build number?

Open any Office application like Word, click on 'File' in the top left corner, and select 'Account' (or 'Office Account'). Your version number, build number, and installation type (e.g., Microsoft 365 Apps) will be listed under the 'Product Information' section on the right.

Is it safe to roll back to an older version of Microsoft Office?

Rolling back is a valid temporary troubleshooting step for workflow-breaking bugs. However, older builds may lack the latest security patches. It is recommended to use the rollback as a temporary workaround and re-enable updates once Microsoft officially resolves the issue.
