How to Fix Word Documents Not Previewing in Explorer

The File Explorer preview pane in Windows 11 is a convenient feature that lets you quickly view Word documents without opening Microsoft Word. But sometimes, the preview simply stops working — showing a blank pane, an error message, or nothing at all when you select a .docx file.

If Word document previews are not showing in File Explorer, it’s usually caused by a missing preview handler, corrupted Office registry entries, or disabled preview settings. In this guide, we’ll go step-by-step through how to fix Word document previews not working in Windows 11.

Fix Word Documents Not Previewing in Explorer

Make sure you have Microsoft Word installed on your PC and that it’s activated properly. You’ll also need administrator access to modify some settings and registry entries.

Tip: If you’re using a third-party file viewer or an older version of Microsoft Office, some of these steps may differ slightly — but the methods below apply to most modern setups.

Step 1: Enable the Preview Pane in File Explorer

Before diving into advanced fixes, make sure the Preview Pane is actually turned on.

1. Open File Explorer (press Windows + E).
2. Click the View tab at the top toolbar.
3. Select Show → Preview pane.

Now, select a .docx or .doc file. If the preview still doesn’t appear, continue with the next steps.

Step 2: Check Default App Association for Word Files

If Windows isn’t using Microsoft Word as the default app for .docx files, File Explorer may not be able to generate previews.

1. Open Settings → Apps → Default apps.
2. In the search box, type Word and click Microsoft Word.
3. Scroll down and ensure .doc and .docx are set to open with Microsoft Word.
4. If not, click each file type and choose Microsoft Word as the default.

After changing the defaults, restart File Explorer and check if previews start working.

Step 3: Verify the Word Preview Handler Is Enabled in the Registry

Microsoft Word uses a built-in preview handler that allows File Explorer to display Word document previews. If the registry entry is missing or damaged, previews will stop appearing.

1. Press Windows + R, type regedit, and press Enter.
2. Navigate to the following path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\PreviewHandlers
3. In the right pane, look for this key: {84F66100-FF7C-4fb4-B0C0-02CD7FB668FE}
4. The corresponding value should be: Microsoft Word previewer

If it’s missing:

1. Right-click in the right pane and choose New → String Value.
2. Name it {84F66100-FF7C-4fb4-B0C0-02CD7FB668FE}.
3. Double-click it and set the value to Microsoft Word previewer.

Close the Registry Editor and restart your PC. The preview handler should now function correctly.

Step 4: Repair Microsoft Office Installation

Corrupted or incomplete Office installation files can also cause the preview handler to malfunction. You can repair Word without reinstalling it completely.

1. Press Windows + I and go to Apps → Installed apps.
2. Scroll down and find Microsoft Office (or Microsoft 365).
3. Click the three dots (⋯) next to it and select Modify.
4. Choose Quick Repair, then click Repair.
5. If that doesn’t help, repeat the process and select Online Repair for a deeper fix.

After repairing, restart your PC and check whether the File Explorer preview is working again.

Step 5: Enable Word Preview Handlers in Options

Microsoft Word has a built-in setting that controls whether it allows file previews in Windows Explorer.

1. Open Microsoft Word.
2. Click File → Options.
3. In the General section, scroll down to User Interface options.
4. Ensure that Enable Live Preview is checked.
5. Next, switch to the Trust Center tab → click Trust Center Settings → File Block Settings.
6. Make sure that Open and Save options for Word documents are not blocked.

Click OK twice to save your settings and close Word. Now test the preview feature again in File Explorer.

Step 6: Re-register the Preview Handler DLL File

If the Word previewer’s DLL file is unregistered, Windows can’t use it to render previews. You can re-register it using Command Prompt.

1. Press Windows + X and select Windows Terminal (Admin) or Command Prompt (Admin).
2. Run the following command: regsvr32 /i shdocvw.dll
3. Press Enter and wait for the confirmation message.

Restart your system afterward and check the preview pane again.

Step 7: Check File Explorer Preview Settings

Sometimes, previews are disabled globally through File Explorer settings.

1. Open File Explorer.
2. Click View → Options → Folder Options.
3. Under the View tab, scroll through the Advanced settings.
4. Make sure Always show icons, never thumbnails is unchecked.
5. Also, ensure Show preview handlers in preview pane is checked.
6. Click Apply and then OK.

Now reopen the same folder containing your Word documents and test the preview feature.

Step 8: Disable Third-Party Add-ins in Word

Conflicting Word add-ins can interfere with the preview handler. You can check this by disabling them temporarily.

1. Open Word and go to File → Options → Add-ins.
2. At the bottom, select COM Add-ins from the dropdown and click Go.
3. Uncheck all listed add-ins and click OK.
4. Close and reopen Word, then test previewing documents in File Explorer.

If the issue is fixed, re-enable the add-ins one by one to identify the problematic one.

Step 9: Reset the File Explorer Cache

A corrupted cache can also prevent previews from appearing properly.

1. Open File Explorer and navigate to this folder: %localappdata%\Microsoft\Windows\Explorer
2. Delete all files that start with thumbcache and iconcache.
3. Restart your computer.

Windows will rebuild the cache automatically, which often restores missing previews.

Step 10: Reinstall Microsoft Office (Last Resort)

If none of the above methods work, your Office installation might be severely corrupted. A clean reinstall can reset all preview-related components.

1. Press Windows + I → Apps → Installed apps.
2. Locate Microsoft Office and click Uninstall.
3. Restart your PC.
4. Download and reinstall Office from your Microsoft 365 account portal.

Once reinstalled, open Word once to register its preview handlers, and then check File Explorer again.

Wrapping Up

When Word document previews stop working in File Explorer, it’s usually due to missing registry entries, disabled preview options, or an Office configuration issue. By enabling the preview pane, re-registering the Word preview handler, and ensuring Office is properly installed, you can quickly restore this useful feature.

If you often rely on previews for productivity, keeping Microsoft Office updated and occasionally clearing File Explorer’s cache will help prevent the issue from returning.

After applying these steps, your Word files should display clean, instant previews in File Explorer once again — exactly as they should.
