This is when you should worry about deleting old drivers from the system to free up disk space from the system volume. The old drivers keep on taking up hard drive space and eventually will fill up the system drive. While Windows keeps on adding and installing new drivers, it will not delete the old ones. If new drivers are available for a particular device, Windows will automatically try to download and install the latest version through Windows Update. Over time, Windows will keep on installing device drivers for all new hardware plugged into the PC like printers, USB devices, monitors, etc. Since the files inside this folder are critical for system functioning, it is advisable not to touch the folder. Windows 10 saves all the drivers inside of this folder called DriverStore. Windows 10 comes with a collection of trusted driver packages of the most common hardware from Microsoft and third-party vendors. Without drivers installed, Windows will not be able to communicate with the hardware.

The drivers are a bridge of communication between the software Operating System and the hardware. They tell the Operating System how to operate a particular hardware device. Device drivers are an important component of Windows.
