I have a question about the Windows Components Wizard that I was wondering if someone who knows would be kind enough to answer. My OS is XP Home with Service Pack 2. The instructions read: "To add or remove a component, click the checkbox." The word "or" is what's confusing me. Are the instructions trying to tell me that if a specific component's box is checked, if that component is installed, it will be removed, AND if that component is removed it will be installed? In other words, all checked components will go "vice-versa" of their state before the Wizard is run? The reason I ask is because I am trying a trick from a book entitled "Windows XP Hacks" that uninstalls Windows Messenger (never once used it; never will). And if my understanding is correct, how can you tell whether a specific component is removed or installed? Is there a way, or are you just supposed to work with one component at a time (in other words,do you need to know beforehand if a specific component is removed or installed)? Thank you to all who take the time to answer my question!
