Just sharing my experience. Many do not support/condone using the “all in one” OS maintenance/Registry cleaners. Although CCleaner seems to be accepted.
Now I have been using JV16 power tools on my OS’s for well many years and I personally have never had any issue or problems from the use of this software and found the benefits effective.
I don’t recommend the use of any of these programs as some people have had devastating negative experiences.
Each to their own.
