Modified `Git Bash.vbs` script from Git for Windows to support ansicon and a default working directory. Batch file can be pinned to taskbar with alt. icon. Running from VBScript is gross, but ensures an up to date environment without killing explorer or logging in/out

Git Bash.vbs

Set fso = CreateObject("Scripting.FileSystemObject")
Set shell = CreateObject("WScript.Shell")

' Lookup System and User environment variables defined in the current process
Set env = shell.Environment("PROCESS")

Const TemporaryFolder = 2
linkfile = fso.BuildPath(fso.GetSpecialFolder(TemporaryFolder), "Git Bash.lnk")
gitdir = fso.GetParentFolderName(WScript.ScriptFullName)
ansicon = fso.BuildPath(env("ANSICON64"), "ansicon.exe")

' Dynamically create a shortcut with the current directory as the working directory.
Set link = shell.CreateShortcut(linkfile)

if ansicon <> "" then
    link.TargetPath = ansicon
    link.Arguments = fso.BuildPath(gitdir, "bin\bash.exe") + " --login -i"
else
    link.TargetPath = fso.BuildPath(gitdir, "bin\bash.exe")
    link.Arguments = "--login -i"
end if

link.IconLocation = fso.BuildPath(gitdir, "etc\git.ico")
if WScript.Arguments.Length > 0 then
    link.WorkingDirectory = WScript.Arguments(0)
else
    link.WorkingDirectory = env("HOME")
end if
link.Save

Set app = CreateObject("Shell.Application")
app.ShellExecute linkfile
