Here at Frankenstein Computers, we often get asked about registry cleaners.  We strongly recommend that you do NOT use third-party cleaners on your system.

Registry cleaners are software utilities that attempt to remove configuration data from the Windows Registry that is no longer in use or that is unwanted on the system. Such data may include information left by software that has not been uninstalled completely from the computer, information that is no longer of use, or settings required for the operation of malware. A registry cleaner scans the registry, and attempts to pick out the unnecessary values in order to delete or repair them.

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. Removing certain registry data can prevent the system from starting, or cause errors and crashes.

There is no reliable way for a third-party program to know whether any particular key is invalid or redundant. Poorly designed registry cleaners may not know for sure whether a key is still being used by Windows or what detrimental effects removing it may have.

I’m just saying…
