This is one I can never work out. If I want to remove a component the Windows Components Wizard Appears. This says "To add or remove a component, click the checkbox. I'm looking at this and , for example, I want to remove Windows Messenger. The box is blank. If I tick this, will it be removed or added? Now, a couple of items are ticked which are already installed - Windows Media Player, etc. Other already installed programmes are not ticked. So if I tick items, will they be removed with the already ticked items, or do I need to untick ticked items to prevent removal? A nightmare. Thank you for anu advice. Grant.
