I got a stupid question but I never really thought about it before. Will my Windows XP activation key ever wear out? In the past 3 weeks I've reformatted a few times trying different things with dual boot using Windows and Linux (basically I screwed up the grub loader a few times and had to reformat 3 times...) Well hey I'm new to Linux! lol. So I've used my activation key a total of 4 times. I'm wondering where there will be a point where they will say its invalid? Is there some defense to be sure I'm not just installing it onto 4 different computers? Yeah just thought I'd ask.
