Frequently Asked Questions
Why does Adobe Acrobat install a thumbnail preview handler?
Adobe Acrobat installs this handler by default so users can see a graphical preview of the first page of a PDF directly within Windows Explorer, replacing the standard generic PDF file icon.
Can I disable PDF thumbnails directly in Windows Settings?
Yes. You can open File Explorer Options, navigate to the View tab, and check 'Always show icons, never thumbnails'. However, this setting globally disables thumbnails for all file types (like images and videos), not just PDFs.
Will removing the Thumbnail Preview Handler affect my ability to open PDFs?
No. Removing the thumbnail handler only stops Windows Explorer from rendering visual page previews for PDF files. You will still be able to open, read, and edit PDFs normally in your chosen PDF reader.
