Modify Your Default Applications in Windows 10
Microsoft has built-in applications in Windows 10 to handle just about every file you want to open, however you may want to modify which applications are used by default for certain tasks.
This KB Article describes how to choose which applications Windows 10 uses for certain tasks.
For example, you may want to use Outlook as your default email application rather than Windows Mail. Or you may prefer to use Google Chrome as your default web browser rather than Microsoft Edge. Also, you may wish to modify which application is used when you double-click to open certain file types, such as PDFs.
To begin, in the Windows start menu, search for 'default' and launch the Default app settings option.
For example, here you can change your default Email application from Windows Mail to Outlook.
For example, here you can change your default web browser from Microsoft Edge to Google Chrome.
If you scroll down and select Choose default apps by file type, you can select which application you prefer is used to open specific file extensions.
For example, here you can modify which application is used when you double-click to open PDFs.
Finally, if you wish to open a file using an application other than the current Windows 10 default, you can right-click the file in File Explorer, hover over Open with >, and choose an alternate application.
