I am using CCleaner for many years and never experienced that it removed something that it shouldn’t. You will have to select the “register cleaning” multiple times though before it has cleaned everything it can. Just let it scan/fix things untill nothing more is found. Reboot after that to ensure all changes are effective. This last thing (reboot) is needed due to way windows works and has nothing to do with CCleaner (or any other registry cleaner)
