The earlier versions of Windows platforms (Windows 7 or Windows 8) have a universal PDF supported that allow opening PDF files using Acrobat Reader, Adobe Acrobat, or Foxit Reader, or similar programs. But after making an upgrade to Windows 10, PDF files are automatically opened in PDF Explorer even if the Acrobat Reader is installed on the machine.

Microsoft Edge provides only minimal access controls (like zoom in, zoom out, print etc.), and lacks some convenient features, like, sending the PDF as an attachment with Outlook.

• Mozilla Firefox (v52 and above)
• Google Chrome (September 2015 release onwards)
• Apple Safari (v12 and above)
• Microsoft Edge
