Conduct those dangerous samples on a virtual machine or use your real system under of Desktop virtualization process, other than that is already an enough configuration.
In my case , I use Auslogics Registry Cleaner because WiseCare registry cleaner is not very deep . For example: Use the WiseCare and he thinks 230 invalid registry entries .Then use Auslogics Registry Cleaner and finds a considerable amount of registration invalid entries not found by WiseCare .
And in the case of O&O Defrag , I consider more efficient than WiseCare .
