RE: Fingerprint reader stopped working immediately after Windows 10 Anniversary update (version 1607)
Don't know if this will work for all who've posted here, but yesterday (12/7/2016) I noticed a new version of security tools published for the Latitude E5550. So, I downloaded and installed the following, and my fingerprint reader works again!
- Dell ControlVault Firmware (ControlVault_Setup_HTF2M_188.8.131.52_A41_ZPE.exe)
- Dell ControlVault Driver (Security_Driver_HGX2G_WN64_184.108.40.206_A20.EXE)
- Dell Data Protection | Security Tools (STInstaller-220.127.116.11.zip)
It was suggested to me that I didn't need the last one in the list, but I did install it so I'm posting exactly what I installed. Again, this is for a Latitude E5550 and may not apply to you, but it may indicate that new drivers/software have been released for your model as well. You'll want to go to the following link and enter your Service Tag number: http://www.dell.com/support/home/us/en/19/
Here's hoping this helps someone else. Cheers!
