Just updated to 5.64.7613 and sorry I did. Why was Easy Clean deleted?
It wasn't it was just folded/morphed into healthcheck
If you want Easy Clean back then you can modify a registry entry (for now at least).
(Cfg)HealthCheck
Set the value to 0 and Easy Clean will come back in place of Health Check.
The usual warning - Modifying the registry could make your computer unusable, if you are not sure what you are doing then don't touch it.
