Ok Dell finally released the drivers for Windows 8. Its a couple step process so here is how I got it working on all of our machines.
Uninstall Dell Data Protection if you have it installed.
Download the firmware and driver from here:
Extract the firmware and install. You will need to run it in elevated command line and make sure to select the x64 installer.
Once installed you can install the Dell ControlVault Driver
Reboot and you should now see the biometric device. The software will be Broadcom now instead of Dell and you can register your fingerprints.
