Is there any reason to run this app. if everything is running OK?

I came across this while searching for some fixes for someone that was
having a problem with windows XP updates. From the post

"
NOTE - The first time you run CCleaner's Issues scanner you'll have to keep

running it back-to-back until it finds nothing. One scenario is a registry

key may only be a reference pointing to a completely different location in

the registry and when it's removed then that reference link is also noticed

as being invalid on a subsequent scan. It's generally a good idea to keep

running the Issues scan until nothing is listed. "

Got them fixed, but wondering about this.

Seems dangerous in the wrong hands. LOL

Thanks
