With the help of Registry Purify users scan the Windows registry section for any invalid or obsolete entries to delete. The tool also integrates a registry optimizer, in order to reduce size occupied on the disk by registry keys.

The installation procedure is swift and uneventful. Registry Purify's interface is plain and neatly organized. Is is possible to select the Registry areas to scan, between ActiveX and COM entries, font and uninstall keys, shared DLLs, application paths, help files information, Windows startup items, file extensions, history list, Start menu entries, and others.

The scanner generates results with total found invalid registry keys, along with each entry's registry path, write time, value name, and invalid data reference.

Registry Purify lets you open an entry in Registry Editor to tinker with settings, check or uncheck all items for one-click deletion, as well as backup the registry in case Windows starts experiencing issues after modifications are made. Restoring settings to an earlier point can be done from the Clean menu.

The Registry optimizer does not take a long time to finish, and it displays a summary of the initial and resulted size along with ratio for each processed registry section. A system restart is required to apply the new changes; this power option is immediately triggered as soon as you click the Ok button.

As with other registry cleaners, multiple scans and deletion tasks might be required to leave the registry squeaky clean. The tool has a good response time, requires a light amount of CPU and memory, and carries out a task rapidly and without errors, whether it's scanning, repairing or optimizing. Although Registry Purify doesn't leave much room for customization, it offers users a simple solution to Windows registry maintenance.
