I'd developed this module which facilitates the way to add or remove an external application to Windows startup trhough registry methodology.
It covers the startup scope (Run/RunOnce), the user scope (Current User/All Users), the registry scope (x86/x64) and also is capable to add a bypass for "Secure mode" windows logon.
An example usage:
WinStartupUtil.Add(UserScope.CurrentUser, StartupScope.Run, RegistryScope.System32, title:="Application Title", filePath:="C:\Application.exe", arguments:="/Arg1", secureModeByPass:=True) WinStartupUtil.Remove(UserScope.CurrentUser, StartupScope.Run, RegistryScope.System32, title:="Application Title", throwOnMissingValue:=True)
