Editors' reviewThis program is a suite of Windows system maintenance tools to clean and optimize your computer, but we're not impressed with the way it handles the task. Dr. System integrates your Windows system tools, including the temp files cleaner, ScanDisk, and Defragmenter, into a plain, outdated interface. It frees up disk space by quickly scanning your PC for temporary files and throws them in the Recycle Bin, though we would prefer permanent deletion instead. The scheduler is easy to set up, and rightfully so since it allows you to automate cleanings only at start-up. Its defragmentation process tells how much free space was recovered, but gives no indicators of its progress along the way. You won't be able to specify items or cleaning locations with Dr. System. Since it relies heavily on Windows' Defragmenter and ScanDisk tools, we don't see much value in this application. Easy to use, this freeware program doesn't compare to the extensive measures taken by other optimizer tools.
Dr. System operations are faster than regular system maintenance tasks, because Dr. System runs the standard Microsoft Windows system utilities in a highly optimized environment. Because most other functions on your PC are disabled in this environment, there are fewer external applications writing to disk or using up your valuable system memory while these programs run.
