You will need to check your computer manufacturer's website on the Support Downloads page for your model to look for the apps you want.
I found the fingerprint reader here: http://www.csd.toshiba.com/cgi-bin/t...lFamily=804517
Check Windows Updates for any newer drivers
, then your Device manager to see any missing drivers which you can also download from the page above.
Perhaps your computer came with an Apps/Drivers CD where you can also look for these.
Or Google the exact name for the hardware listed in the Device Manager and search for the app and/or driver
