TortoiseHg is a Windows shell extension and a series of applications for the Mercurial distributed revision control system. It also includes a Gnome/Nautilus extension and a CLI wrapper application so the TortoiseHG tools can be used on non-Windows platforms.

Acknowledgement: The TortoiseHg installer for Windows includes the TortoiseOverlays handler, as provided by the TortoiseSVN project.
