Internet download accelerator is very fast, but isn't freeware anymore, but there is "Free Download Manager" instead.
The plugin "Flashgot" will allow you to use this download manager (or others) wiht Firefox or mozilla. And I guess this fast download manager won't remain free. So hurry.
You have Hotkeyz by Skynergy ; a utility for all those text snippets you repeatedly have to type, so this program allows you to do it via a few hotkeys.
Another utility is RunIt : you begin to type the first letters of a program you need, and RunIt finds it in seconds. (

Or Find and Run Robot, which is doing more or less the same.
Very handy.
"Startdreck" will show you all the programs that run at startup, and where they are hidden.
neo trace express shows you where a website is located on a map of the world : a kind of visual traceroute.
"Asc to tab" will allow you to transform a simple text to a htlm page with all the urls linkable.
"Open expert" allows you to open a file, using a different program than the one you would normally use. Sometimes you want to hear a wav in Winamp instead of Windows media player". For those who frequently change programs.
Maxmem will allow you to occasionaly free up the ram.
And for the Pocket Pc there is a free scrabble-like program on sourceforge.net for ppc's with windows mobile 2003 : xwords (also available for Palm), including foreign dictionaries.
Oggdrop : drop a file on it, and it converts to ogg, the new open source replacement for mp3 (better quality in a smaller file)
We owe those programmers a lot !!
