How many drivers are built into Windows 7?

Windows 7 includes a wide range of nearby driver libraries. In the basic installation of the operating system, these drivers are stored in the driver store, which is located in the %SystemRoot%System32DriverStoreFileRepository directory. In addition, a subfolder corresponding to the localized driver information is also saved in the DriverStore folder. For each language configured on the system, there is a corresponding subfolder here.
In the driver store, each device driver is certified and fully compatible with Windows 7 systems, with Microsoft's digital signature, which ensures that the driver is absolutely available in the operating system. When installing a new compatible Plug and Play device, Windows 7 checks for available compatible device drivers in the driver store. If found, the operating system will automatically install the device.
