Answer 1

You need to use the $Window.WindowState property to say whether the form should be minimized, maximized or restored to normal. The code below shows how it can be done.

#Minimize the Window
$MinimizeButton.Add_Click({
    $Window.WindowState = 'Minimized'
})
$MaxRestoreButton.Add_Click({
    If ($Window.WindowState -eq 'Normal') {
        #Maximize the window
        $Window.WindowState = 'Maximized'
    } Else {
        #Put window back to its normal size if maximized already
        $Window.WindowState = 'Normal'
    }
})
