Its time to open up your toolbox and share those little programs you can't live without. Trackback or comment with yours, I'm sure we'll all learn something.

My list is mostly web development stuff I suppose:

Nattyware's Pixie

Pixie is a free program that sits in your taskbar and gives you the color your mouse is hovering over in just about any format you could hope for. If you ctrl-alt-c it will copy the hex to your clipboard. I've found it invaluable for me whenever doing anything with color design.

Irfanview

Irfanview is a free image viewer. It views just about any image format known to man. It also lets you do batch cropping, canvas editing etc. It has a small footprint and I find it much better than firing up a clunky editor for certain tasks.

Winamp v2.95

Still the best windows-based lightweight music player. ever. Its too bad the current versions are so bloated. oldversions.com!

Steganos Security suite

This suite is always my first install on a fresh machine. Its not a free product, but its been worth every dime. Encrypted hard drive abilties, anonymous browsing without using scary proxy sites, anti-theft laptop protection, etc etc

Color Blender

Eric Meyer's color blender. Provide it two colors and find a coordinating list of up to 10 in between's. A great compliment to using Kuler.

CSS Sculptor

Eric Meyer's standard compliant CSS tool. This is a great tool that comes pre-packaged with 30 standards-based CSS templates, and allows you to easily customize your design and maintain standards. Its about $150, but does help with lowering development time if you are not a css guru up on the quarterly hacks!
