Windows Application Default Association with Workspace ONE UEM

On Windows the association of a file extension, can be done by the user or programmatically. Microsoft offer a CSP to do exactly that and so Workspace ONE UEM can do it too with custom profile.

It is possible to configure the machine to have a predefined association list, to do so you need a clean machine with all the association done.

Export Association XML

To export the association profile you need to run the following command.

dism /online /export-defaultappassociations:C:\Temp\ApplicationDefault.xml

This will give you the current association with each extension.

Example

<?xml version="1.0" encoding="UTF-8"?>

Note : Microsoft does not publicly document the format of that XML. So it’s always best to export it from a clean machine.

Create association profile

You will need to convert the XML to a base64 string.

You can use notepad++ using the “MIME Tools” plugin.

Install Profile

Add the base64 generated previous into the Data section

<Replace>
	<CmdID>889b5b44-4b36-4c74-8277-abca0ec8184b</CmdID>
	<Item>
		<Target>
			<LocURI>./Vendor/MSFT/Policy/Config/ApplicationDefaults/DefaultAssociationsConfiguration</LocURI>
		</Target>
		<Data> { base64 string } </Data>
	</Item>
</Replace>

Remove Profile

<Delete>
	<CmdID>889b5b44-4b36-4c74-8277-abca0ec8184b</CmdID>
	<Item>
		<Target>
			<LocURI>./Vendor/MSFT/Policy/Config/ApplicationDefaults/DefaultAssociationsConfiguration</LocURI>
		</Target>
	</Item>
</Delete>
