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'
}
})
