Ryan wants to make his desktop comfortable to work. For this, he wants the following settings on his computer: The Paint icon should appear on the taskbar. The taskbar should not be visible when the user is working on the applications. Two recently used program icons should be displayed on the Start menu. The Start menu should have the System administrative tools option.
