It's pretty neat to have but it wasn't the best user interface for me.
It was bloating my context menu with far too many options across my whole computer so I had to tranquilise it.
To do that, just open up a command prompt or the "Run" window (with Windows+R).
Assuming that you installed Windows Git to C:\Program Files\Git\
Type in:
cd %PROGRAMFILES%\git\git-cheetah && regsvr32 /u git_s
hell_ext.dll
And menu be-gone!
Now go and install something more intuitive like TortoiseGit.
