Microsoft_Edge.jpeg

Microsoft has adopted the Chromium open source project in the development of Microsoft Edge on the desktop to create better web compatibility. This new Microsoft Edge runs on the same Chromium web engine as the Google Chrome browser, offering you best in class web compatibility and performance.

The new Chromium based Microsoft Edge is supported on all versions of Windows 7, Windows 8.1, Windows 10, Windows Server (2016 and above), Windows Server (2008 R2 to 2012 R2), and macOS.

When you click/tap on a link for a PDF file in Microsoft Edge, the PDF file will open in Microsoft Edge using the internal PDF viewer by default.

If you turn on Always open PDF files externally, Microsoft Edge treats PDF files as downloads and lets users open them with the default app instead.

This tutorial will show you how to enable or disable always open PDF files externally in the Chromium based Microsoft Edge.

Contents

  • Option One: Turn On or Off "Always open PDF files externally" in Microsoft Edge in Microsoft Edge Settings
  • Option Two: Enable or Disable "Always open PDF files externally" in Microsoft Edge for All Users using a REG file

5 You can now close the Settings tab if you like.





OPTION TWO

Enable or Disable "Always open PDF files externally" in Microsoft Edge for All Users using a REG file


You must be signed in as an administrator to do this option.

This option uses the AlwaysOpenPdfExternally policy to enable or disable the internal PDF viewer in Microsoft Edge. If you enable this policy Microsoft Edge treats PDF files as downloads and lets users open them with the default application. If you don't configure this policy or disable it, Microsoft Edge will open PDF files (unless the user disables it in Option One).

The downloadable .reg files below will add and modify the DWORD value in the registry key below.

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge

AlwaysOpenPdfExternally DWORD

(delete) = Default
0 = Always disabled
1 = Always enabled


1 Do step 2 (enable), step 3 (disable), or step 4 (default) below for what you would like to do.
