A2Z RegClean

A2Z RegClean is a software application designed to scan the computer for broken registry entries and remove them, in order to boost the Windows performance. It comes packed with a few intuitive options that can be tinkered with easily.

Rapid setup and user-friendly GUI

The installation procedure takes little time to finish. As for the interface, A2Z RegClean adopts a normal window with a seemingly cluttered layout, where you can start the registry scan with the click of a button.

Scan the registry and fix all issues

A2Z RegClean looks into application history, system control classes and other parts of the registry. Unfortunately, it does not give users the possibility of handpicking the areas to scan while excluding the rest, in order to improve scan speed.
Results show the full path for each invalid registry key. It is not possible to select the ones to fix, so you have to repair all of them. This is not possible in the demo version, however.
In addition, you can back up the original registry keys and restore them later if Windows starts experiencing stability issues after the new modifications. There are no other notable options available here.

Evaluation and conclusion

The app may take a while to complete a scan job but it uses low CPU and RAM in the meantime, so it does not affect the overall performance of the PC or interrupt normal user activity,. No error dialogs were shown in our tests, and the tool did not hang or crash.
The full package is very expensive however, especially when taking into account that more powerful registry cleaners are free to use. The demo version does not permit you to fix any issues to see if the program actually works.
