Is there any nearly unknown software you use a lot that you absolutely can't live without? I browse download.com once in a while and I occasionally come across something that kicks major ass. I personally use "TrayClip" from
http://www.chtsoft.com/TrayClip.htm
Since I am a programmer, I have a few snippets of code that I frequently use. TrayClip allows me to keep all the snippets of code organized so I can paste them in easily. It also keeps track of the last X number of items that were in your clipboard so you can easily paste them again if necessary. I couldn't live without this little program.
