- Observed behavior
- The preview pane fails to display document contents in File Explorer, the Word Open dialog, Print Preview, or taskbar thumbnails despite trying various fixes.

Use File Explorer Preview Pane Instead of Word Open Dialog
Bypass the known preview bug within the Microsoft Word Open dialog by previewing your documents directly in Windows File Explorer.
There is a longstanding issue affecting document previews within the internal Open dialog box of some Microsoft Word and Windows versions. Testing the file in the native Windows File Explorer helps isolate whether the issue is with Office or Windows.
Press the Windows Key + E on your keyboard to launch a new File Explorer window.
Click on the 'View' tab at the top of the window, then select 'Preview pane' to ensure it is toggled on. You can also press Alt + P.
Navigate to the folder containing your Microsoft 365 document, click the file once, and check if the preview generates successfully on the right side of the screen.

Access Print Preview via Keyboard Shortcuts
Quickly access the Print Preview screen in the desktop application without navigating through complicated menus.
Try WPS Office for Reliable Document Management
Since preview pane errors are often caused by longstanding Microsoft Office handler bugs, switching to WPS Office provides a free, lightweight, and highly compatible alternative that handles document previews smoothly without conflicting with Windows File Explorer.
- 1. Download and Install: Visit the official WPS Office website to download the free installer and follow the quick setup wizard.
- 2. Set as Default: Set WPS Office as your default application for .docx files to enable its built-in preview handlers.
- 3. Open and Preview: Enjoy fast document loading and reliable previews directly from your file manager.

Frequently Asked Questions
Why does my File Explorer say 'No preview available' for Word documents?
This commonly occurs due to a corrupted or conflicting Microsoft Office preview handler in the Windows registry. Repairing your Office installation via the Control Panel or switching to an alternative suite like WPS Office can resolve the handler issue.
Can I use the preview pane with Word for the web?
Word for the web operates within your browser and does not use the Windows File Explorer preview pane. To preview online files, use the preview features built into your cloud storage provider (like OneDrive) or download the file to preview it locally.
How do I fix taskbar thumbnails not showing for Word documents?
If hovering over the Word icon on your taskbar only shows text instead of a document thumbnail, check your Windows visual settings. Press Win + R, type 'sysdm.cpl', go to the Advanced tab, click Settings under Performance, and ensure 'Save taskbar thumbnail previews' is checked.
