After running Ccleaner and supposedly removing 30 or so trackers , I run it again 5 minutes later and it will supposedly have found 150 trackers . this is an ongoing issue and it may even do the same thing if checked again immediately .The old version never did this

That's simply because Health Check calls more things 'Trackers' than the previous Easy Clean did.

As for why some things come back after cleaning it's simply the way Windows works.

It will also happen if you have your browser (or other apps) synced.
