Im collecting a list of Windows Store Applications. Im using this powershell script : 

Get-AppxPackage -AllUsers

This gives me back multiple applications.

I want to know if there is a unique value for an application that stays the same when the application is updated!

This is an example from one application with its values. This is an example from one application with its values.

    Look at the `PackageFullName`, it consists of 4 parts. The second part is the version of the package which will change in upgrade while the other 3 parts stay the same. You can use a combination of the 1st+3rd+4th part, which is unique. – kennyzx Jun 20 '18 at 08:34

For the people who are looking for an answer, Kenny named the solution.

I quote :

What is the PackageFamilyName (PFN)?

If i have 2 the same applications, x64 and x86. The PackageFamilyName is the same.

That is correct, because it is the same app, but built for different architectures.
