I'm an obsessive CCleaner user, cleaning several times/day. Is this good, bad or indifferent relevant to performance and reliability? Thank you!
With a SSD, I guess indifferent to performance, and bad for reliability.
If you have problems that are fixed with cc cleaner, then fix the source of the problem first.
I bet you will not notice any difference if you abandon cccleaner use completely. Try it and see.
