WinSCP

WinSCP is an open source free FTP & sFTP client for Windows. Beyond file transfer, WinSCP offers file management & file synchronization functionality. One of it's biggest advantages its simple user interface - which mimics Windows Explorer (there is one that mimics Norton Commander as well) in both looks and functionality - making a it extremely user-friendly for an avid Windows users. For me, drag-and-drop feature and the ability to see my folder structure is very handy. Even the tool icons look the same as in Windows Explorer, so you will never get lost, even without a manual or a geeky friend next to you.

ImageSizer

ImageSizer is one of the easiest photo tools I've used in a long time. It serves a simple purpose of batch resizing your pictures and then either saving them in a folder or compressing to a .zip file. So simple, yet so useful.

Jing

Jing is a very nifty and user friendly screen capture application from TechSmith. You can use it to snap a picture or even record a video of your computer screen and then share the media with whom every you might like over web, email or IM.

The Electric Sheep

Electric Sheep is a free & open source screensaver created by Scott Draves. It is by far the most beautiful and captivating screensaver I've ever came across. It not only generates amazing images, but it does it "on the fly". When the computer "falls asleep" it starts communicating and collaborating with thousands of computers around the world morphing computer animations known as "sheep". The result of this constant transformation is what some call a collective "android dream", an reference to Philip K. Dick's novel "Do Androids Dream of Electric Sheep?".
