How to Fix Windows 10 PDF Preview Pane Not Working
Question details
The user is unable to view PDF files in the Windows 10 File Explorer preview pane and experiences failures when trying to select or delete multiple PDF files.
- Product
- PDF Handlers / Windows File Explorer
- Device & OS
- Windows 10
- Scenario
- Attempting to preview, select, or manage PDF files within Windows File Explorer.
- Observed behavior
- The preview pane fails to display PDF content, and multi-file selection or deletion operations do not respond, suggesting a system or handler conflict.
Verify if the issue is specific to PDF files or if the preview pane fails for all file types like images or Word documents. This helps determine whether the problem lies with your PDF reader settings or the Windows operating system itself.
Enable Preview Pane and Configure PDF Reader Settings
Ensure the preview pane is activated in File Explorer and your PDF software is properly configured to generate thumbnails and previews.
Often, the default PDF handler loses its configuration after a Windows update or a software upgrade. Resetting these preferences forces Windows to recognize the preview generation tool again.
Open File Explorer in Windows 10. Click the 'View' tab at the top of the window, then select 'Preview pane' to ensure it is turned on.
Right-click any PDF file, select 'Open with' > 'Choose another app'. Select your preferred PDF reader, check 'Always use this app to open .pdf files', and click OK.
Open your PDF reader's preferences (for example, in Acrobat, navigate to Edit > Preferences > General). Check the box labeled 'Enable PDF thumbnail previews in Windows Explorer' and click OK. You may need to restart your computer for changes to take effect.
Restart File Explorer and Fix Windows Glitches
If you also cannot select or delete multiple files, the issue might be rooted in a stuck Windows File Explorer process or folder permission errors.

Frequently Asked Questions
Why does my File Explorer crash when I click on a PDF file?
File Explorer can freeze or crash if the default PDF handler is corrupted, outdated, or conflicting with the Windows preview framework. Updating your PDF software or switching to a lighter alternative like WPS Office often resolves this issue.
How do I fix a 'File in Use' error when trying to delete a PDF?
This happens when the preview pane locks the file to read its contents. To delete the file, temporarily turn off the preview pane (View > Preview pane), delete the PDF, and then turn the preview pane back on.
Can I use the preview pane for PDFs in Windows 11?
Yes, the preview pane is fully supported in Windows 11. You can enable it by opening File Explorer, clicking 'View' on the top command bar, selecting 'Show', and then clicking 'Preview pane'.
