Today I installed Windows 8 Release Preview on my laptop in a production environment. All went well until I installed the fingerprint reader driver (Validity Fingerprint Driver) from HP web site (this driver is for the Windows 7). When installation and initialization of the fingerprint reader was finished, I did restart after which Windows would not start, screen just flashes. Only you can do is to restore you system to the earlier time or like in my case, install your Windows 8 RP from the scratch and find appropriate driver.
It was easy and if you have HP Elitebook 8560w you can download appropriate driver for fingerprint reader from here.
The second thing that could be useful! If you are using more than two monitors, like me, and this monitors are connected with USB-to-DVI adapter, Windows 8 don’t have appropriate driver. So, if you want use monitors with mentioned adapters, download and install driver/application from DisplayLink site and enjoy in multiple monitors and in Windows 8 RP.
That’s it for today and have a nice weekend
