CCleaner is a wonderful tool that you can use for a number of purposes.
Some of these tasks include removing unnecessary files and freeing up space, tell you what type of files are taking up too much space as well as manage and delete restore points.
Apart from this, CCleaner can clean up parts of Windows that are not associated with the Registry.
If you needed to clean your Registry, then you’d ideally go with CCleaner.
Of course, if there’s any flaw in your Registry, it will be both tough and dangerous for a program to detect this. Any attempt to fix this will definitely make things all that more worse.
So, in order to prevent any angry tech support calls, Registry cleaners only look for keys that aren’t of any use. Pertinently, this includes keys from uninstalled programs.
It goes without saying that these keys that serve no purpose won’t hurt your system either.
What should also be pointed out is that keeping these keys will result in an unnecessarily large Registry. Yet the size pales in comparison with the sizes of the SSDs and hard drives available today.
In other words, it doesn’t take up much room either.
So, even though in theory, your Registry should slow down the process, it really do this by very much.
What this translates to is that even after a Registry clean, your boot time speed will hardly be noticeable.
To put things in perspective, while cleaning your Registry won’t hurt your PC, it will not help much either.
