CCleaner Pro failing to start at system boot. in CCleaner Bug Reporting Posted April 3 Yeah, I pinned it to the taskbar and disabled the launch at restart. I don't run the auto updates and go get them manually when it tells me there is a new version. The only thing that really had me confused was the Smart Cleaning. I've been using this app for years and never realized what was keeping the icon active in the taskbar. I'm all good, thanks again!
