Na formulář přidejte tlačítko Command1 a na jeho událost Click:

Private Sub Command1_Click() 

   'Dotaz na nové jméno registrované organizace
   strOrganization$ = InputBox("Organisation:") 
   If strOrganization$ = "" Then 
      MsgBox "Empty String", vbCritical, "Error" 
      Exit Sub 
   End If 
   'Uložení do registru 
   Call savestring(HKEY_LOCAL_MACHINE, _    "Software\Microsoft\Windows\CurrentVersion", _    "RegisteredOrganization", strOrganization$) 
   'Dotaz na nového vlastníka
   strOwner$ = InputBox("Owner:") 
   If strOwner$ = "" Then 
      MsgBox "Empty String", vbCritical, "Error" 
      Exit Sub 
   End If 
   'Uložení do registru 
   Call savestring(HKEY_LOCAL_MACHINE, _    "Software\Microsoft\Windows\CurrentVersion", _    "RegisteredOwner", strOwner$) 

End Sub

Spusťte projekt. Pokud vše proběhne v pořádku, změní se organizace a uživatel. Ověřit si to můžete v Ovládacích panelech/Systém/Obecné.
