Hello,
Recently I've tested and compared popular registry(system) cleaners and noticed cool function in Revo Registry Cleaner – Registry Tuner. for me it's like killer feature, because there are many useful tweaks (by default, many options are hidden in GUI of Windows.
Indeed, you can say that every user can manually edit registry for necessary hidden option in windows. It might be killer feature for jv16 if add uninstalr for uninstallation function and registry tuner as additional supplement feature to system fixer, so many users can leave only one universal tool(jv16) and delete Revo registry cleaner and BCUninstaller, CCleaner etc.

Thank you for the tip! I'll look into adding this feature.
