RegSeeker is a small and powerful app that allows you to search for any item that resides in your system registry. You can export/delete the results and open them to view in the registry.
The app can display various degrees of information about your system, such as your start-up entries and histories, and installed apps. RegSeeker also includes a powerful registry cleaning tool and a file tool that allows you to locate any duplicate files and broken/bad short-cuts.
RegSeeker lets you control your system's start-up entries, services, drivers, histories and junk files. You can also view all the data regarding the apps that are installed and your browsers extensions.
The downside to this app is the complex layout and slower performance compared to other registry cleaning tools that are available. It also provides a few notifications during the process, rather than at the end, which can become annoying.
