Registry Key Remover
Registry Key Remover is a lightweight and portable software application that can help you restore a previous state of the Windows registry that was not yet altered by the installation of programs, by relying on snapshots previously taken with RegShot.
Since installation is not required, you can drop the app directory anywhere on the hard disk and just click the executable file to run.
Another possibility is to save Registry Key Remover to a USB flash disk or similar storage unit, in order to run it on any PC directly, without installing anything beforehand.
Straightforward GUI and options
The interface is user-friendly, consisting of a single window that provides immediate access to all existing options. All you have to do is select the action type between generating an NSIS script and reverting changes, as well as indicate the RegShot text document for comparing logs, along with the NSIS script output file and directory.
Evaluation and conclusion
The tool does not put a strain on PC performance, since it runs on low CPU and RAM. It has a good response time and carries out tasks rapidly. On the other hand, it has not been updated for a long time.
