Whether PC Doctor came with your PC or you installed it with the PC Doctor Toolbox package, you can remove it using the Windows Control Panel. The PC Doctor installation disc doesn't include an uninstaller package, but it provides Windows with all the information needed to remove its program files and application data. After uninstalling PC Doctor, you can confirm that none of its system-wide configuration files remain on your computer by checking the Roaming folder in your AppData directory.

Hold the "Windows" key and press "X," then select "Control Panel" from the quick access menu.
Select "Uninstall a Program" from the Programs section if you're viewing Control Panel in Category mode. Alternatively, click "Programs and Features" if you're viewing Control Panel in Icon mode.
Select "PC Doctor" from the list of programs and click "Uninstall." Confirm the program removal in the pop-up window when prompted. The uninstaller takes 30 seconds to a minute to remove the program.
Hold down the "Windows" key and press "R" to open the Run dialog. Type "%appdata%" (without quotes) and press "Enter" to open AppData's Roaming directory. If PC Doctor left behind any configuration files, the Roaming directory contains a PC Doctor folder. If you don't plan to install PC Doctor again, you can safely delete this folder.
