Supongo que te refiers a la imagen que se pone en el menu inicio de windows
Private Declare Function GetUserName Lib "advapi32.dll" Alias "GetUserNameA" (ByVal lpBuffer As String, nSize As Long) As Long
Private Sub Form_Load()
Me.Picture = LoadPicture(GetUserImage)
End Sub
Private Function GetUserImage() As String
On Error Resume Next
Dim StrUserName As String, El_Objeto As Object
StrUserName = String(100, Chr$(0))
GetUserName StrUserName, 100
StrUserName = Left$(StrUserName, InStr(StrUserName, Chr$(0)) - 1)
Set El_Objeto = CreateObject("WScript.Shell")
GetUserImage = El_Objeto.RegRead("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Hints\" & StrUserName & "\PictureSource")
End Function
