Os dejo la solución de como evitar el evento de la rueda del ratón y asi evitar el cambio de registro por parte del usuario cuando usa una aplicación creada en ACCESS.

Debes crear un modulo con el siguiente code —>>

Option Compare Database
Option Explicit

Private Declare Function LoadLibrary Lib "kernel32" _
Alias "LoadLibraryA" (ByVal lpLibFileName As String) As Long

Private Declare Function FreeLibrary Lib "kernel32" _
(ByVal hLibModule As Long) As Long

Private Declare Function StopMouseWheel Lib "MouseHook" _
(ByVal hWnd As Long, ByVal AccessThreadID As Long, Optional ByVal blIsGlobal As Boolean = False) As Boolean

Private Declare Function StartMouseWheel Lib "MouseHook" _
(ByVal hWnd As Long) As Boolean

Private Declare Function GetCurrentThreadId Lib "kernel32" () As Long

' Instance returned from LoadLibrary call
Private hLib As Long

Public Function MouseWheelON() As Boolean
MouseWheelON = StartMouseWheel(Application.hWndAccessApp)
If hLib <> 0 Then
hLib = FreeLibrary(hLib)
End If
End Function

Public Function MouseWheelOFF(Optional GlobalHook As Boolean = False) As Boolean
Dim s As String
Dim blRet As Boolean
Dim AccessThreadID As Long

On Error Resume Next
‘ Our error string
s = “Sorry…cannot find the MouseHook.dll file” & vbCrLf
s = s & “Please copy the MouseHook.dll file to your Windows System folder or into the same folder as this Access MDB.”

‘ OK Try to load the DLL assuming it is in the Window System folder
hLib = LoadLibrary(”MouseHook.dll”)
If hLib = 0 Then
‘ See if the DLL is in the same folder as this MDB
‘ CurrentDB works with both A97 and A2K or higher
hLib = LoadLibrary(CurrentDBDir() & “MouseHook.dll”)
If hLib = 0 Then
MsgBox s, vbOKOnly, “MISSING MOUSEHOOK.dll FILE”
MouseWheelOFF = False
Exit Function
End If
End If

‘ Get the ID for this thread
AccessThreadID = GetCurrentThreadId()
‘ Call our MouseHook function in the MouseHook dll.
‘ Please not the Optional GlobalHook BOOLEAN parameter
‘ Several developers asked for the MouseHook to be able to work with
‘ multiple instances of Access. In order to accomodate this request I
‘ have modified the function to allow the caller to
‘ specify a thread specific(this current instance of Access only) or
‘ a global(all applications) MouseWheel Hook.
‘ Only use the GlobalHook if you will be running multiple instances of Access!
MouseWheelOFF = StopMouseWheel(Application.hWndAccessApp, AccessThreadID, GlobalHook)

End Function

‘******************** Code Begin ***************
‘
Function CurrentDBDir() As String
Dim strDBPath As String
Dim strDBFile As String
strDBPath = CurrentDb.Name
strDBFile = Dir(strDBPath)
CurrentDBDir = Left$(strDBPath, Len(strDBPath) - Len(strDBFile))
End Function
‘******************** Code End ****************

Y debes copiar la DLL MouseHook.dll en el directorio windows.
