The PDF Shell component in Acrobat and Acrobat Reader allows you to see the thumbnails of PDF documents in Windows explorer, on both 64-bit and 32-bit versions of Windows. By default, this feature is OFF. You can enable it using a specific setting available in the preferences.
- Open Acrobat or Acrobat Reader. On the Edit menu, choose Preferences.
- In the Preferences dialog box, choose General in the Categories list, and then select the Set As Default PDF Handler button.
- You will be prompted for confirmation.
- Wait for a few seconds while Acrobat is configured to show thumbnail previews in Windows Explorer.
