I suggested CCleaner because not all startups are visible in services and the more unnecessary one’s are more easily seen and disabled in this manner, WinPatrol is also great for this montoring.
CCleaner is a perfectly safe program for anyone to use as long as they don’t tinker with the default settings, CCleaner also doesn’t claim to fix anything that is broken it is simply a more effective cleaner than the default windows version and it has proven itself a safer and more thorough tool than many others without ruining systems.
