    Const TOKEN_ADJUST_PRIVILEGES As Integer = &H20
    Const SE_RESTORE_NAME As String = "SeRestorePrivilege"

    Dim hProc, hToken As IntPtr
    Dim luid_Restore, As Long
    Dim tp As New TOKEN_PRIVILEGES

    ' get the current process's token
    hProc = Process.GetCurrentProcess().Handle
    hToken = IntPtr.Zero
    If Not OpenProcessToken(hProc, TOKEN_ADJUST_PRIVILEGES Or TOKEN_QUERY, hToken) Then
        Return False
    End If

    ' get the LUID for the Restore privilege (provided it already exist)
    luid_Restore = 0
    If Not LookupPrivilegeValue(Nothing, SE_RESTORE_NAME, luid_Restore) Then
        Return False
    End If

    tp.PrivilegeCount = 1
    tp.Privilege.Luid = luid_Restore
    tp.Privilege.Attributes = SE_PRIVILEGE_ENABLED

    ' enable the privileges
    If Not AdjustTokenPrivileges(hToken, False, tp, 0, IntPtr.Zero, IntPtr.Zero) Then
        Return False
