RegSupreme Pro - Registry Cleaner |
The Registry Cleaner analyzes the entire Windows registry and lists the erroneous, obsolete and unneeded items.

The Registry Cleaner of RegSupreme Pro is not just "a registry cleaner" but "the registry cleaner" of jv16 PowerTools. The feature uses advanced stateful registry scanning technology which means it doesn't scan the registry entry by entry but analyzes it as a whole.
Stateful registry cleaning
While competitive products consider each erroneous piece of registry data as an individual error RegSupreme Pro' Registry Cleaner understands that there are usually dozens of registry entries and keys relating to a single registry error, they are not all individual errors. This error link analysis is very difficult but it allows RegSupreme Pro' Registry Cleaner to give you the best possible registry cleaning and fixing results.
The Registry Cleaner's link analysis goes even beyond this, it also analyses how fixing or removing a single registry error affects the entire registry. For example, does it invalidate other registry data or does it fix other registry errors.
Detects and fixes more registry errors
PowerTools' registry cleaner engine can also detect non-referenced registry errors. In English: If you install a software, for example WinZip but you don't like it and decide to uninstall it. Of course, the product's own uninstaller leaves something behind, as usual. While other registry cleaners might be able to detect and remove leftover data which have direct references to WinZip, such as a path (e.g. "C:\Program Files\WinZip\") or filename reference (e.g. "C:\Program Files\WinZip\WinZip.exe").
But RegSupreme Pro's Registry Cleaner can detect also leftover data that doesn't have any references, such as path or file references, to the software in question. This isn't magic but advanced software installation pattern recognition system. To this day we have installed thousands of different software to our test computers and detected patterns on what data they modify and add to the computer when installed and what they leave behind when uninstalled. This unique information was used to create the leftover software scanning module to the Registry Cleaner.
All this, and still easy to use
Does all this sound very complex? Well, it is. But all this is working under the hood of the product, all you have to do is download RegSupreme Pro and click the Start button.
Results window
The found registry errors are listed in categories for easy browsing through the list. The Fix button first attempts to automatically fix the problem. If no solution is found the erroneous data is removed. The Custom Fix opens the Custom Fixing Tool (see the next paragraph), and the Delete button removes the erroneous data from the registry.
Custom Fixing
Advanced users can take full advantage of their knowledge and use the Custom Fixing Tool which allows you to decide which solution suggestions are the best for each of the found errors.
Other Features
- Includes 18 different registry scan methods which can all run at the same time
- A generic MRU list and history data cleaner can flush the privacy-threatening history data of hundreds of applications
- Finds obsolete file extension definitions, Add/Remove list entries, unused font declarations, left-over software entries, application paths, shared component definitions and invalid ActiveX and COM/DCOM registrations

The Registry Cleaner also contains a Scan Report feature which shows you information about the found errors and about the general health of your system.
The tool's design goal has always been: it's better to occasionally miss an invalid item than to list valid items as errors. This policy has made our products highly trusted Windows optimization tools.
