I just downloaded the newest version of CCleaner as of this writing (1.20.118) and I am not sure if the issues scanning was there before or not, but its new to me. Anyway, I scanned for all issues but I am hesitant to clean the results, mainly the ones dealing with unused file extensions. What exactly does it do to "fix" those particular issues? Does it just the reference to the extension in the registry? Does it add a reference to it? Does it delete the files with those extensions? Just want to make sure what I'm doing before I do it Thanks in advance for any info.
