I'm no fan of that OS but still some people are working with it - so here is a short installation tutorial for working with git on a ms windows machine.

You have to install three software packages:

• PuTTy: for the ssh connection and for generating ssh key pairs (http://the.earth.li/~sgtatham/putty/latest/x86/putty-0.61-installer.exe)
• msysGit: provides git for windows (http://msysgit.googlecode.com/files/msysGit-fullinstall-1.7.6-preview20110708.exe)
• TortoiseGit: a nice integration of the git commands into the Windows Explorer (like Tortoise SVN for Subversion) (http://code.google.com/p/tortoisegit/downloads/list) note that there is a 32-Bit and 64-Bit msi installer.

• start puttygen.exe
• press generate and move your mouse in the small screen
• optional and i don't know if TortoiseGit can handle passphrase protected keys: you can type in a passphrase to protect your key - then you will be asked for it every time you connect
• save private and public key

Create a local repository - open Windows Explorer:

• Create an empty folder and right-click into it.
• Choose “Git Create repository here”
• Create repository

Repository Settings (right click and go to repository settings)

1. Git → Config
   • set your username
   • set your email
   • set your full name

1. Git → Remote (and click on “Add new”)
   • insert url: ssh:/ /username@iis.uibk.ac.at:2222/projects/git/REPONAME
   • PuTTy Key: select the private key you generated

right click on the directory (git repository)

• in the Tortoise-Git Menu select 'Pull'
• for 'remote' select 'origin'
• check 'AutoLoad Putty Key'
• for 'Remote Branch' select or type 'master'
