A user named User1 uses a shared computer that runs Windows 7. User1 is a standard user.

User1 attempts to connect a USB device to the computer and is prompted to enter administrative credentials.

You need to ensure that User1 can use the USB device without requiring administrative credentials.

What should you do first?

A.
Add User1 to the Power Users group.

B.
Run Pnputil.exe and specify the i a parameters.

C.
Run Driverquery.exe and specify the /SI parameter.

D.
Copy the driver files to the C:\windows\system32 folder.

Explanation:
When a driver is staged, it is placed in the device driver store and non-administrators can install the device, provided they have permission to install devices in the appropriate device setup class.

Pnputil.exe is a command line utility that you can use to manage the driver store. You can use Pnputil to add driver packages, remove driver packages, and list driver packages that are in the store.

-i Specifies to install the identified INF file. Cannot be used in conjunction with the -f parameter.

Example
pnputil.exe -i -a a:\usbcam\USBCAM.INF Adds and installs the specified driver
