Thanks How do I delete the apps?
You have to find every app that is not bundled with OS X & delete it. That means Pages, Numbers, Keynote, iMovie… Many Apple apps are not shipped with the standard OS X installation unless you have a build for a specific model that included them (yes it is that confusing). You also need to remove every third party app that came from the App store.
Frankly it is far easier to erase & reinstall if you do not know what you are looking for. Obviously a full backup is essential before you begin.

OS X is not tied to the Apple ID
Then one must wonder why the installer app has the Mac App Store receipt with one's Apple ID encoded in it?
Believe what you like, but until you test you are just making assumptions.
It is very simple to test…
Install OS X under Apple ID A (install an older version to cause updates to be needed).
Try updating OS X when signed into the store as Apple ID B.
I did that & found it worked.
Now install Apps from Apple ID A & try updating them from Apple ID B - you can't, apps 'lock' the Apple ID into the store.
Note: Spotlight indexes other attached disks so be sure that no apps are on any connected disks otherwise that Apple ID will be 'locked' in the store.
You can have multiple Apple ID's & can install OS X on any Mac you 'own or control', so read the terms if you think this this is 'illegal'. It may be unlawful to keep the OS from another user - it is not transferable if it didn't ship with the original Mac as you already know.
Post your findings if you test it.
