TortoiseSVN
TortoiseSVN provides a nice and easy user interface for Subversion, and as a Subversion client, TortoiseSVN has all the features of Subversion itself, including: most current CVS features; directories, renames, and file meta-data are versioned; commits are truly atomic; branching and tagging are cheap (constant time) operations; efficient handling of binary files.
