FREE Software Thread - Utilities & Applications You Cannot Live Without

I've dropped AdAware 2007 from my arsenal of tools. This new version runs a service in the background to keep it updated, and it can be a hefty resource hog. Yes, it's true, the one time leader in the Spyware battles now runs constantly in the background.....
 
Looking at the stuff in my Programs menu, I also use "Audiograbber," which is a free CD-ripping program (makes it easy to rip the songs off of your enhanced cds) and also does some file conversion and recording stuff using it's line-in function) (you can set it to record LPs and it automatically splits them into tracks) and other stuff.

There's also "Rename It," which can rename files, either their file names or extensions, in batches. Useful for guys like Maki who want to change the extensions and names of all their porn files to non-searchable or playable file formats and back after each "session" ;)
