Because of this loophole in Registry Cleaners, they often led to the situation like loss of functionality, system inability and Microsofts application compatibility updates to block malicious Registry Cleaners.

Registry Cleaners have their own limitations for instance they cannot correct scenarios like undeletable registry keys owing to insertion of null characters in their names. Some specialized tools such as Sysinternals (now Microsoft) and RegDelNull utility can perform this task.

Capability of Recovery:

A registry hive, which a system is unable to mount, cant be repaired by a registry cleaner.

Nevertheless, it can recover a corrupt registry in numerous ways backed by Microsoft; for example, Automated System Recovery, from a Last Known Good configuration, by enabling the setup to re-run or by deploying System Restore.

Cleaning of Malware:

Despite all these problems, a corrupt registry can be recovered in several ways supported by Microsoft. For instance Automated System Recovery by using System Restore or by running setup from the Last Known Good boot menu.

Registry cleaners are unable to sense or flush out registry entries related to a rootkit that tends to conceal this fact from other procedures.

It is a must for a specialized tool to compare results from raw core registry storage with that given by Registry API.

Virtualization of application:

Registry Cleaners could not remove those Registry entries which are written for a virtualized application.
