Advantages of registry cleaners…
Registry cleaners, or registry cleanup software, may improve the performance of computers by ridding the registry of redundant information.
Due to the sheer size and complexity of the registry database, manually cleaning up debris and invalid entries would be impractical, so registry cleaners are essentially tools that automate the process of looking for invalid entries, missing file references or broken links within the registry and resolving them.
The correction of an invalid registry key can provide some benefits.Windows has concluded that registry cleaners will continue to have a role until most applications have moved to the .NET Framework platform that does not rely on the registry for application settings.
Some registry cleaners offer backup and restore functions that allow the user to revert changes made by the registry cleaner in case they are undesired. A registry cleaner may be useful for someone that adds or removes programs from their computer very often; however, a virtual machine is a faster and more reliable means of reverting an operating system to a previous good known state in a testing scenario.
Disadvantages of registry cleaners…
Some registry cleaners make no distinction as to the severity of the errors, and many that do may erroneously categorize errors as "critical" with little basis to support it.

Answer 2

In my world, they are pretty much useless. As i'd rather reinstall my OS, then doing temporary solutions.


In best case scenario they make your computer faster, and fix corrupted data.


Worst case, they delete vital files from your system32 folder.





Ccleaner is always good for uninstalling though.

Answer 3

some people swear by them.others call them useless.i don't use them anymore and i don't have any performance issues.if you decide you want to try one out always make a back up before deletion.ccleaner and any good registry cleaner will always give you that option.why back up? because it is possible for a registry cleaner to delete something you really need and then your system is hosed.
