By default, Git uses whatever you’ve set as your default text editor or else falls back to the Vi editor to create and edit your commit and tag messages. To change that default to something else, you can use the
core.editor setting. Example for setting default Git editor in Windows to Notepad++:
git config --global core.editor "'C:/Program Files (x86)/Notepad++/notepad++.exe' -multiInst -notabbar -nosession -noPlugin"
Note: use above as a one line command.
