Вопрос

Как сделать, чтобы программа добавлялась в автозагрузку (не в меню "Автозагрузка", а в реестр)?

Ответ

Для этого необходимо создать в разделе реестра
HKEY_LOCAL_MACHINE\ Software\ Microsoft\ Windows\ CurrentVersion\ Run строковый параметр. В значении параметра установить путь программы.
В модуле пишешь:

Option Explicit
Public Const REG_SZ As Long = 1
Public Const REG_DWORD As Long = 4
Public Const HKEY_LOCAL_MACHINE = &H80000002
Public Const HKEY_CLASSES_ROOT = &H80000000
Public Const HKEY_CURRENT_USER = &H80000001
Public Const HKEY_USERS = &H80000003
Public Const ERROR_NONE = 0
Public Const ERROR_BADDB = 1
Public Const ERROR_BADKEY = 2
Public Const ERROR_CANTOPEN = 3
Public Const ERROR_CANTREAD = 4
Public Const ERROR_CANTWRITE = 5
Public Const ERROR_OUTOFMEMORY = 6
Public Const ERROR_INVALID_PARAMETER = 7
Public Const ERROR_ACCESS_DENIED = 8
Public Const ERROR_INVALID_PARAMETERS = 87
Public Const ERROR_NO_MORE_ITEMS = 259
Public Const KEY_ALL_ACCESS = &H3F
Public Const REG_OPTION_NON_VOLATILE = 0

В примере написан полный код работы с реестром, если необходимо только записать данные, то лишнее можно убрать.
Применение:

Private Sub Command1_Click()
Dim path As String
path = "Software\Microsoft\Windows\CurrentVersion\Run"
CreateNewKey HKEY_LOCAL_MACHINE, path
SetKeyValue HKEY_LOCAL_MACHINE, path, "Назавание программы", "здесь пишешь полный путь программы", REG_SZ
End Sub
