Script to remove Registrar Registry Manager

ShellExecute('rr.original.exe')
WinWait("[CLASS:TNagForm]")
WinClose("[CLASS:TNagForm]")
ControlMove("[CLASS:TMainForm]", "", "TPanel2",4, 88, 400, 915)

Above is AutoIt script that will launch registrar registry manager and close the nag screen automatically. The lite version is really a good replacement for regedit aside from it having a nag screen.
