This is easiest, but may not necessarily find the latest or most appropriate drivers.
Windows 10/Windows 8/Windows 7/Vista: Click then using the "Category" view, click "Hardware and Sound", find "Devices and Printers" near the top of the screen then click on "Device Manager" (the last item in the list underneath).
You can also view a video of the rollback process on Windows Vista later.
After the update (even if more recent drivers were not found), you should right-click over the device again, click Properties and then on the Driver tab to check the "Driver Provider".
Problems such as recordings freezing up, difficulty in selecting the correct, working input source or having the full range of input sources available, usually mean your sound device has faulty, outdated or inappropriate drivers.
If this occurs it is important that the drivers are updated.
Windows Update is potentially less reliable about obtaining appropriate hardware updates than Windows Device Manager.
If you suspect a driver update problem, launch Device Manager from the Windows Control Panel.
