Device Doctor is a free and effective tool for updating device drivers in Windows and installing the missing ones. The program is based on a huge database of drivers, whose size according to the developers exceeds 3 terabytes and contains software for more than 13 million devices. Device Doctor supports all built-in computer components, offering support for processors, chipsets, graphics and sound chipsets, network cards, various types of controllers, cameras, bluetooth modules, mouse and computer keyboards and many others.

When Device Doctor starts up, it conducts a thorough system analysis in search of outdated or missing drivers. When this process is complete, it displays a list of devices for which new driver versions are available. In the next step, you can download and install the ingredients you have selected.

The tool is also available in the extended paid version marked as Pro. It also offers a driver backup option, a set of features to increase Windows performance, remove redundant files from the drive, and removes the transfer speed limit when downloading components from the manufacturer's database.
