2. Auslogics Registry Cleaner
Being advertised as “the best tool to safely and effectively clear invalid entries from your Windows registry”, many Auslogics users would agree that it is a great tool for correcting errors caused by a specific registry key that’s preventing a program installing or operating as it should. This is worry-free software because if you're having difficulties with deciding which to remove permanently and accidentally loses some of the entries you unexpectedly need on the next day, allowing you to restore it using the Rescue Center option.
CCleaner’s registry cleaner examines different types of unused registry entries while giving you the opportunity to make a backup before removing them, presenting you with the details of each error that it now labels as ‘issue’ and corresponding actions you would possibly take.

4. SlimCleaner Free
With solid maintenance tools as its main feature, SlimCleaner could provide you with detailed search results and comes up with a superb program manager. And though it only has limited filtering options, there’s enough detail to aid you to make a well-weighed decision about what to retain and what to eliminate.
5. Iolo System Mechanic
Iolo System Mechanic is free, but it requires its users to submit an email address in order to access the 'quick scans' feature and to receive an activation key to activate the cleanup tools. It's not a big price to pay for the utility of it, but you will be hit with some annoying emails. Again, it's ultimately worth it.
You can make use of the free version for basic scanning and cleaning but upgrading for the premium version would give you the access to some of its optimization options. Just like other utility software, you can also restore the database to its previous state with the help of its SafetyNet function though you won't be notified when an auto backup happens and you'll end up with no idea where to find it. So start sweeping your storage from time to time to get familiarized with the changes in files.
JetClean performs deep scans but just like Iolo System Mechanic, it lacks transparency with some details that users may want or need specifically the details about its search results and the function of each registry entry. There are a lot of promises that JetClean offers that could rival any other utility software available on the market but then again, the failure to provide the thorough details would cause doubt and confusion to users.
