The software abylon LOGON offers a comfortable way to protect your computer against illegal access. You only need to train your smart card, your removable media (e. g. memory stick), or a CD/DVD with your windows login data and in the future this medium is your authentication for the computer.
Seems to be quite well liked, where you can find a review.
As with all Giveaway of the Day installers, you can obtain the original installer if you run it on the day of the deal...
Launch the installer (but don't install) then goto your temp folder ("Local SettingsTemp" - show hidden files).
Sort by date and the newest ".tmp" file is the original installer.
Copy it elsewhere and rename it to .exe and you've got a reusable installer!
