RTKF puts a powerful registry cleaning tool into your hands. It quickly finds unwanted registry data. You can safely delete "orphaned" entries and other "rubbish" left behind by "trial" and other software. Most "uninstall" programs DO NOT really clean up after their parent programs. With RTKF you can streamline the registry and perhaps even improve Windows' speed and reliability. Registry "debris" from improper uninstallation routines is a major problem in Windows. RTKF helps users address this issue by giving them software that finally lets them take control of those sometimes "hidden" registry entries used by trial period software. Unfortunately this software has an annoying habit of leaving behind data which adds to the size of the registry. Install and then remove a few of these programs and you'll find your system getting slower and perhaps even crashing more. Removing these useless entries reduces Windows' memory needs and has other benefits as well.
