One of the most important update in Windows 10 is the introduction of Microsoft Edge. Not only was it introduced as Windows 10's default browser to replace Internet Explorer, it was also programmed to be the default PDF viewer. This latter simply means that Windows 10 users will automatically use this application when they open PDF files. This is great because it eliminates the need to install a third-party PDF viewer that could potentially bog down your computer.

However, those who frequently uses the PDF file format may find Microsoft Edge a little bit limited in its capabilities. Therefore, if you have more dynamic software that you prefer to use instead, you will be happy to know that you can change the default PDF viewer on Windows 10 so that your PDF documents will automatically be opened in the software.

If you trust the developer, you can tell your Mac to open it anyway. Warning: Gatekeeper is a security feature, and it’s on by default for a reason. Only run apps you trust. To open an unsigned app, you need to right-click or Control-click the app and select “Open”. This works on macOS Sierra as well as previous versions of macOS.

A pop-up window will prompt you to choose your preferred software. Tick the 'Always use this app' check box and click 'OK'.

Method 2. Using Control Panel

Step 1. Open Control Panel

Open your PC's Control Panel and click on 'Default Programs'. Proceed with accessing the 'Associate a file type or protocol with a program' settings. It will take some time for your PC to load all your file formats.
