There are lots of freeware websites. Some, however, waste your time by listing trialware as well as genuine freeware. An example of a good freeware site is FreewareHome at http://www.freewarehome.com/
Sites for open source software include The OSSwin project: Open Source for Windowshttp://osswin.sourceforge.net/. This might be a little overwhelming.
