Windows Doctor is a PC utility designed to speed up your operating system.
The way it does this is by scanning for vulnerabilities, then it clears activity logs and fixes broken registry keys. It also prevents security threats and helps you recover lost data.

When it comes to graphics attributes, this tool has a well-organized layout, with five major tabs and a left options display panel. Also, the contrast between yellow, black, and white offers great visualization of the main window.

The product embeds lots of features. I'll talk about which I consider being the most important.

First is the System Booster, which is responsible for the analysis of system configuration, and locating the problems that may slow down the computer, in order to fix the problems and optimize the system. Then is the Registry Cleaner, that finds and removes unnecessary or invalid registry entries from Windows registry, thus improving the overall system performance.

Another major feature is represented by System Security, which detects and fixes security and third-party applications vulnerabilities, and prevents the intrusion of Trojans and other malicious programs in the system.

Other mentionable features are Privacy Cleaner, that clears program histories; Data Recovery, involved in searching for lost files, or the Disk Analyzer, that generates a hard disk space consumption report.

All in all, besides being such a comprehensive tool, Windows Doctor was impressive for me because of its minimal impact on system resources and its system responsiveness.
