This single executable allows you to use Notepad as your editor any time Git requires one (commits, interactive rebase, etc).
Good news! As of GitPad 1.2, the default editor will be whatever editor is associated with .txt files. Normally, that's Notepad, but if you like a different editor, you can now use that instead.
Just copy GitPad.exe to a folder and double-click on it. It will install itself into your Application Data directory (%AppData%) - if your default editor is not set, GitPad.exe will set itself to EDITOR via setting an Environment Variable on your user profile.
GitPad requires .NET 2.0 or higher.
Remove HKEY_CURRENT_USER\Environment\EDITOR from the registry and reboot your system.
