I am an IT Admin also and I don’t recommend CCleaner for any Windows OS.
MS also Recommends that you don’t use ANY Registry cleaner. If MS thought it was a good idea they would have purchase a company that created a registry cleaner and implemented it into Windows (that is how Defender made it’s way into Windows and many other programs and utilities).
Just search the web for reason not to use CCleaner.
Just say “no” to these type of programs.
