And most importantly understand there's no such thing as a free lunch and free apps are malware. Learn how to backup your data and reinstall Windows every year. Learn how to manage your computer and keep it clean. There's no magic software that's going to make your computer all better again.

It's malware and it opens the door for more problems like breaking your registry or letting in other third parties to your computer. If you're using CC cleaner than you don't know what you're doing. You're just looking for a quick and dirty solution to make your computer go faster, or pretend that you are good at IT administration. You can uninstall the apps you don't need, you can delete temporary folders, and windows has driver updates built in, under settings security updates, click the link that says additional driver updates. Why are you trying to clean up your registry? Windows registry is a cluster-fuck of active directories buried inside old active directories, drivers and links for hardware that hasn't been used in 10 years, and beyond cleanability even with a brand new install. Even if it's not directly through that app, they sell your computer access to a fake virus company and then you have to pay to get rid of the pop-ups. CC cleaner along with many other malware, or freeware apps, typically will look like they're helping but often they create problems in order to sell you the solution. From my experience, CCleaner commonly just removes files that are properly managed, but it seems like they arent. I read your post too fast I thought you had an app called registry.
