What is the function of the 'Device Manager' in Windows?

The function of 'Device Manager' in Windows is to manage hardware devices and their drivers. This tool allows users and system administrators to view and control the hardware attached to the computer. Within Device Manager, users can see a list of all hardware components, including graphics cards, hard drives, and network adapters. It provides essential functionality such as installing and updating drivers, disabling or enabling hardware, and troubleshooting any issues that may occur with the devices.

By managing the drivers associated with hardware, Device Manager helps ensure that the devices operate correctly and can communicate with the operating system. This is crucial for the overall performance and stability of the computer system. The ability to identify device conflicts or issues also aids in maintaining optimal hardware functionality.

The other options do not accurately represent the primary role of Device Manager. Managing software applications pertains to different system tools, internet troubleshooting is handled by network-related settings and diagnostic tools, and user account creation is managed through the 'User Accounts' section in the operating system settings.
