Published by Alvin Nyau - Updated on

So, you want to open PDF files with your favorite reader (Adobe Acrobat Reader or other PDF viewer app) but instead Windows 10 will always open PDF with another app such as Microsoft Edge, Chrome or Firefox. Here’s a quick guide on how to change default PDF Viewer in Windows 10 and what to do if you cannot change the default PDF Viewer using the normal way.

Change Default PDF Viewer in Windows 10

If you haven’t set any app as the default program to associate PDF file type, Windows 10 will always ask for which program you would like to open the PDF file with when you open any PDF file. To set a default app to view PDF file type in Windows 10, follow the steps below. As an example, we will set the default PDF Viewer in Windows 10 to Adobe Acrobat Reader DC.

  1. Press Win+i keys to open Settings app.
  2. Select Apps, then from the left pane, click on Default apps.
  3. In the right pane, scroll down and click on the Choose default apps by file type link.Choose default apps PDF file type Windows 10

In some cases when you browse the web and open any PDF file online with Microsoft Edge, Edge will seem to hijack and set itself as the default PDF Viewer in Windows 10 again. This has always been a major issue for users who use Microsoft Edge as their default browser.

To prevent Edge from force changing the default PDF Viewer in Windows 10 without your consent, use the following command (without touching the Group Policy or Registry).

Go to start menu or Cortana to search for CMD. Right-click Command Prompt from the search result and then select Run as administrator. Paste the following command into the command prompt and hit Enter key.

for /f "usebackq" %i in ('reg query hkcr /f "AppX"') do reg query %i\DefaultIcon | find "MicrosoftEdgePDF" && reg add %i /v NoOpenWith /t REG_SZ /f

Change default PDF viewer from Adobe Reader to Acrobat Pro or Acrobat DC

Sometimes even after changing the default viewer to Acrobat XI Pro or DC, Windows 10 would still open PDF with Adobe Reader. This is due to the default program preferences set within the Adobe programs itself when you have multiple Adobe products installed in your computer.

To change the default PDF viewer in Windows 10 to Adobe Reader, Acrobat Pro, Acrobat DC or Writer, follow the guide below.

Let’s say you want to change the default PDF viewer to Acrobat Pro. Open Acrobat Pro, then click on Edit from the menu. Select Preferences, then General from the left pane. Under Application Startup, click on the Select As Default PDF Handler button to set Acrobat Pro as the default PDF viewer in Windows 10.

Change default PDF viewer to Adobe Acrobat Reader DC Pro

Another alternative method is to simply uninstall other Adobe products except for the one that you want it to be the default PDF viewer. This should also work to fix the issue.
