This is probably not new information, but I have not run an AdwCleaner scan for some years. But since purchasing Win10 systems and finally getting around to an AdwCleaner scan (for no particular reason) I got these positive detections:

***** [ Preinstalled Software ] *****

To be fair, these Dell registry entries are not described as malware, but as "pre-installed software" that one might like to remove, following a routine on-demand scan.

My own take on these Dell Assist and Update and Help/support agents is that they are unnecessary but benign programs. They have never solved any Dell PC problems I have had, but have occasionally run random system scans I did not authorize. At worst they are a nuisance. On previous Windows operating systems I have deleted them without any regrets.

Any feedback is welcomed.
