[HKEY_CLASSES_ROOT\Directory\Background\shell\HideTaskBar\command]
@="C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\powershell -executionpolicy unrestricted c:\\HideTaskBar.ps1"

[HKEY_CLASSES_ROOT\Directory\Background\shell\SetTaskBar\command]
@="explorer ms-settings:taskbar"

  public static extern IntPtr FindWindow( String sClassName, IntPtr sAppName);

  [DllImport("kernel32.dll")]

"@

$fw = Add-Type -Namespace Win32 -Name Funcs -MemberDefinition $sig -PassThru
$hwnd = Add-Type -Namespace Win32 -Name Funcs -MemberDefinition $sig -PassThru

$sClassName='Shell_TrayWnd' # any existing window name
$wname='Shell_TrayWnd' # any existing window name

$hwnd = $fw::FindWindow( $sClassName, [IntPtr]::Zero ) # returns the Window Handle
$hwnd
$a = $fw::GetLastError()
$a
# WM_SHOWWINDOW 24
# SW_SHOW = 5
# SW_HIDE = 0
#
$fw::SendMessage( $hwnd, 24, 5, 0 ) # OnShowWindow만 콜한다.
$fw::ShowWindow( $hwnd, 5) # 여그서 결정타를 날려야 홈인이다.
