One of the most striking differences between UNIX and MS Windows is the copy and paste behavior using the mouse. This becomes an annoyance if you are used to the UNIX way of doing things and always forget to highlight-right-click-copy when using MS Windows. Andy Polyakov's True X-Mouse Gizmo allows UNIX-like copy-on-select behavior in MS Windows environments. The page also contains useful information about how the utility works and how to modify its behavior, as well as a few things to watch out for. Importantly, it does not remove the traditional MS Windows behavior, so users accustomed to that way of doing things will not notice a difference.
