FOG - Free, Open-Source Ghost
FOG aka Free, Open-Source Ghost as its name suggests is a free open source alternative to Norton Ghost. No idea what either Ghost does? In short, they image a partition/drive (make a duplicate) so you can restore the image at a later time when you invariably screw up. ;) Very handy when you trash your computer often. :)
WirelessKeyView
WirelessKeyViewrecovers all wireless network keys (WEP/WPA) stored in your computer by the 'Wireless Zero Configuration' service of Windows XP and by the 'WLAN AutoConfig' service of Windows Vista. It allows you to easily save all keys to text/html/xml file, or copy a single key to the clipboard.

Ok you can file this under one of those nifty little tools that you can't find when you really need it. But now you know where you can find it. :P
Show's over. Come back tomorrow, different time, same place, for more. :)
