Understanding all the options

Does anyone know what exactly happens if I check the box under Windows Explorer for:

Run ( In Start Menu)

Also, Under “Applications”, I see Windows Store, Applications, ( McAfee Antivirus, Office Adobe Reader DC , MS Office Picture Managet)

Multimedia ( Windows Media Player) , Utilities and Windows.

What is being “cleaned” if I put in a checkmark mext to what is listed?

to find out what is cleaned, right click each one of those entries, click the Analyse choice which will list all the found entries for that category.

each one of the entries in that list can be expanded by double clicking each line to see a detailed report.
