Updating Win32 Apps~
As of writing, Intune doesn't allow you to straight up "replace" an existing app. Instead, we need to create a new Win32 App and 'supersede' the old version.
It's essential to know both the app, and it's shipped configuration. For example some apps may include self-updaters that require no changes, whilst others may require a manual supersede every other day. Some apps may even require the same version installed for the app to be uninstalled correctly.

Once you the new version has been deployed, you can then remove the old app from Intune. This will not uninstall the app from devices, but will prevent it from being reinstalled in the future.
