Set default file associations

In Windows 10, the way to set the a default program or a file association is done with a .xml file and a Group Policy setting, when the computer is joined a domain – otherwise you do it manually.

Export

On a reference computer, setup the program and file association as needed and then export the result:

Edit

Edit the .xml file to  contain the settings you wish to apply to your computer clients. It is not recommended that you use it “as-is”.

Below is my default appAssoc.xml file containing Outlook and Internet Explorer as default apps on a computer.

Copy

Now copy the .xml file to a network location where all your computers can get a hold on the file, eg. %NETLOGON%\ClientApps\appAssoc.xml

Group Policy

In an relevant Group Policy, go to [Computer Configuration], [Administrative Templates], [Windows Components], [File Explore] and select the [Set a default associations configuration file] setting. Enable it and hereafter enter the path and file name, of the location of the .xml file.

At next reboot the new program and file association should be effective.

Office Installer settings

This is a two-part job. First configure the setup installation package for the client computer and afterwards create a Group Policy with additional settings.
