MSysGit vs. Git for Windows

Question

I am having trouble determining the difference between MSysGit and Git for Windows. How are they different? Why would I choose one over the other?

Answer 1

Here is the excerpt 'Official README'

"portable" version of Git for Windows (MSysGit) does not need tobe installed. It will run from any directory you place it in, evenonto a USB thumbdrive. It will not write permanent entries into the Windows registry. It does not need administrator privileges to "install". This version does not offer you the convenient right-click context menu entries "Git GUI Here" and "Git Bash Here", because these would require to add entries into the Windows registry.
