Many types of files are registered in Windows 7, Windows 8, and Windows 10 to be opened by a particular program by default. For example, Notepad typically starts when you open a text (.txt) file. However, you can change which program — including the default settings — opens files of a certain type.
On the Start menu, click Settings.
Click Apps > Default apps.
Click the App you want to change, and then select an App from the list. You can also find new apps in Microsoft Store. Apps must be installed before you can set them as the default.
To choose default apps by file type, scroll down the page, and click the link Choose default apps by file type.
