As I mentioned when talking about last years Software Freedom Day, the OpenCD is a great collection of Open Source utilities for Windows. I've passed this on to many clients for the PDFCreator and the handy collection of other features such as OpenOffice.org and many others. The OpenCD project team has recently released version 4.0. By dropping the Linux LiveCD sampler from the disk, they opened up enough room to add several great programs like the vector drawing Inkscape and the desktop publishing program Scribus. Rease their release announcement here.
