I am going to set up and play around with this application called TortoiseCVS, which is a CVS client that runs on the Microsoft Windows platform. It's officially recommendated by SourceForge. Thanks to Jin for telling me about this cool application. It's free, so you should give it a try too.
Here is an overview of TortoiseCVS from SourceForge:
CVS, Concurrent Versions System, is a centralized Revision Control System (RCS). SourceForge.net provides CVS service to all hosted projects. In order to access our CVS service, you will need to install a CVS client. CVS allows developers to keep a historical record of changes made to their source code tree, and to allow multiple developers to work on a single set of files at the same time without accidentally overwriting changes made by other developers.
TortoiseCVS is a CVS client that runs on the Microsoft Windows platform. TortoiseCVS is integrated with Windows Explorer (Windows Explorer is the file manager in Windows, not the web browser of a similar name, Internet Explorer), rather than a separate stand-alone application. Since most Windows users are comfortable with the Windows Explorer interface, it is often easy for new CVS users to escape the learning curve by using TortoiseCVS.
