CCleaner v5.65 and above now have a new feature called Health Check which can analyze, tune and fix your PC for you, so it runs just right again.
Here is a guide on using it the first time:
If this is the first time you have used CCleaner, then you will see this screen where you click on Take my PC Health Check to continue
You then will be shown some information screens that you need to click Next to continue
Otherwise, if you have used CCleaner before, to run an health Check, make sure Health Check is selected on the left menu and then click on Skip to start Health Check
