Use PowerShell to Retrieve the Package Family Name
Running a specific PowerShell command is the most reliable way to list installed applications and extract their exact package details.
Windows 10 Mobile manages application packages differently than desktop environments. Because registry locations can vary and are often unreliable for this task, utilizing the built-in Windows package manager via PowerShell guarantees you get the correct identifier for Adobe Reader.
Connect your Windows 10 Mobile device and launch a PowerShell window with Administrator privileges.
Type 'Get-AppxPackage' and press Enter to generate a complete list of all installed applications on the device.
Scroll through the generated output list to find the block of information corresponding to Adobe Reader.
Identify the 'PackageFamilyName' field within the Adobe Reader block, copy the value, and paste it into Interop Tools to set your new default PDF viewer.
