The Preview Pane in Windows is a handy feature that allows users to quickly view the contents of files—like images, PDFs, and Word documents—without opening them in a separate application. However, there are times when the Preview Pane may stop functioning properly. Whether it’s not displaying a preview or isn’t responsive at all, there are several ways to troubleshoot and fix this issue.
1. Make Sure the Preview Pane Is Enabled
This may sound basic, but in many cases, the issue is simply that the Preview Pane is not turned on.
- Open File Explorer.
- Click on the View tab in the ribbon at the top of the window.
- Select Preview Pane if it’s not already highlighted.
If this doesn’t resolve the issue, there may be a deeper cause.
2. Restart Windows Explorer
Restarting the Explorer process can resolve temporary glitches that interfere with the Preview Pane.
- Right-click the Taskbar and choose Task Manager.
- Find Windows Explorer in the list.
- Right-click it and select Restart.
This refreshes the file system interface and could resolve the issue immediately.
3. Check File Type Compatibility
Not all file types are supported by the Preview Pane. Common file types like .jpg, .png, .pdf, and .txt usually work, but others may not.
Try opening a known compatible file to test whether the pane functionality is working or not. For unsupported file types, you might need a third-party extension.
4. Disable or Remove Conflicting Applications
Some third-party software, especially PDF readers or antivirus tools, can interfere with the Preview Pane function.
- Boot into Safe Mode and see if the Preview Pane works there.
- If it does, a third-party application may be causing the issue.
- Disable or uninstall recently added programs and check for changes in behavior.
5. Update or Reinstall Relevant Drivers
File rendering in the Preview Pane relies on appropriate drivers, particularly for image and document previews. Make sure your graphic and file drivers are up to date:
- Open Device Manager.
- Locate and right-click on your Display Adapter.
- Select Update driver.
6. Reset File Explorer Settings
Corrupted settings may prevent the Preview Pane from working properly. Resetting File Explorer options can help:
- Open File Explorer and go to the View tab.
- Click on Options on the far right.
- In the Folder Options dialog, click Restore Defaults.
- Press Apply and OK.
7. Modify the Windows Registry (Advanced)
This step is for advanced users. Incorrect registry edits can cause system instability, so create a backup before proceeding.
- Press Win + R, type regedit and hit Enter.
- Navigate to this key:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced - Make sure the value of ShowPreviewHandlers is set to 1.
8. Check Windows Updates
Sometimes a Windows update contains bug fixes or patches that can restore preview functionality.
- Go to Settings > Update & Security > Windows Update.
- Click Check for updates.
Install all available updates and then restart your computer.
