Can someone advise any windows client for GitHub? I found the Tower client Mac (http://www.git-tower.com/) and seems it has very good integration with GitHub via API. Do you know any clients for windows with similar functionality?
Update Yes Thanks all for answers, I know about these three, but they only have integration with GIT, not GitHub. I mean some social features of GitHub, such as review of Incoming Request, comments for these Incoming Request, internal GitHub messaging support, possibility to create new repository on client, manage GitHub repository settings, and similiar features, subscribe to other repository and get notifications when they change. As I know, most of these feature available in GitHub API, but I can't found any windows client that use this API.
GitHub for Windows ( after the popular GitHub for Mac ) with bundled Posh-Git ( powershell extension ) is also available - http://windows.github.com/
Atlassian's SourceTree is also coming soon to Windows - http://blog.bitbucket.org/2013/02/14/sourcetree-for-windows-beta-signup/
