PowerShell module for send WM_SETTINGCHANGE after change Environment variables in Windows

NativeMethods.psm1

Add-Type -Namespace Win32 -Name NativeMethods -MemberDefinition @"
  [DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)]
  public static extern IntPtr SendMessageTimeout(IntPtr hWnd, uint Msg, UIntPtr wParam, string lParam, uint fuFlags, uint uTimeout, out UIntPtr lpdwResult);
"@

function Send-SettingChange {
  $HWND_BROADCAST = [IntPtr] 0xffff;
  $WM_SETTINGCHANGE = 0x1a;
  $result = [UIntPtr]::Zero

  [void] ([Win32.Nativemethods]::SendMessageTimeout($HWND_BROADCAST, $WM_SETTINGCHANGE, [UIntPtr]::Zero, "Environment", 2, 5000, [ref] $result))
}

Works great! Thanks, it's a lot more comforting to use this then to kill explorer.
