PC Doc Pro (formerly PC Doctor Pro)

PC Doctor Pro is a feature-rich software application that promises to fix registry issues and ultimately optimize your PC's performance. It includes a few handy options, such as a backup service and task scheduler.
The interface is split into four main areas for the scan, backup and restore modes, results, and additional tools. In the first panel you can also view the current CPU level, memory usage and network meter.
Scanning the registry is possible in three modes: all areas of your PC, custom, or deep. The latter option is more thorough but takes longer time.
In custom mode you can ask PC Doctor Pro to verify registry problems and junk file remnants, together with disk cleanup and PC tuneup options, as well as to backup all data before making any modifications.
The application looks for Active X and COM issues, uninstall and font entries, shared DLLs, application paths, help file information, Windows startup items, file path references and associations, and other parts of the registry.
For each category in the scan results, you can view the program and key path, along with the priority level (recommended by PC Doctor Pro). It is possible to create an exclusion list and select individual registry keys for repairing.
PC Doctor Pro includes additional tools, which are dedicated to optimizing the system, tuning up Windows and system settings, managing Windows startup programs and IE plugins, and others. However, we haven't noticed any difference in our tests. Regarding program configuration, you can enable scheduling, set junk filters, scan drives for redundant files, and more.
The program uses high CPU and low RAM while scanning the computer, and it may take a while to finish a scan-and-repair job. We have not come across any issues throughout our evaluation, as the app did not hang, crash or pop up error dialogs. Thanks to its intuitive layout, yet comprehensive settings, PC Doctor Pro should please all types of users when it comes to fixing the registry.
