Use the W8.1 driver from your notebook's support page.
This package contains the driver that enables the Validity Fingerprint Sensor in supported notebook models that are running a supported operating system. The fingerprint sensor scans fingerprints for use with biometric security applications.
If you plan on using the fingerprint reader, see if the HP Client Security Manager software for W10 works.
HP Client Security Manager provides enhanced Windows login and website single-sign-on capabilities. Security Manager is also the host for HP Client Security plugins, and therefore should be installed before other Client Security modules. This package is provided for supported models running a supported operating system.
