Currently we have the Patch my PC app running on a server, in here is a difference between intune apps and intune updates. How i've set it up currently:
Intune apps: these are our company apps that we provide and are managed apps that are allowed to create a new app if a new version becomes available.
Intune Updates: These are all the applications that we can find on laptops that are installed by the end user. In here i only let patch my pc create the update application without creating a new app.
With this setup we have a good overview of company managed apps and end user applications. In the cloud portal if i publish an app, it becomes a managed app by default and i'm not able to set it to just create the update version without creating a new app.
In the Cloud Portal, you have the option to create an Update Only assignment - this will create an Update for {Software Name} win32 app in Intune, similar to selecting software from the Intune Updates tab:
