How to Change Default Programs for Opening Files in Windows 11

Sep 14, 2026 | Windows 11

In this video, we are going to change the default program for opening files and email attachments.

This example will use a PDF file, but the process is the same for other types of files like Documents, Spreadsheets or image files.

Start by finding an example of the file type you would like to change. Here on the desktop, we have a PDF file, if I open it, it will open using Edge.

We have Acrobat Reader on this PC and would prefer to use this for viewing PDF files by default.

To do this, right click the PDF file, hover over “Open With”, then select “Choose Another App”.

Select the app you want to use, we’ll choose Adobe Acrobat in this example, then click “Always” to make it the default application.
