I recently installed Windows 10 Pro 64Bit on this Dell Latitude E5540 laptop but can't get the fingerprint working...
Windows had already recognized the the fingerprint reader as Synaptics FP Sensors (WBF) (PID=003f)
kindly help me as soon as possible
Did you install the driver from the support page here?
I found the same issue, I have a backup of the windows/system32 fingerprint drivers and Dll's, I just copy them to the system32 directory, if prompted to overwrite, I skip then re-boot All fixed.
Until the next time M'soft do an update and mess it up again.
