Windows XP has a tendency for the autorun feature to quit working. It is a great feature, and a big headache if you are not real familiar with computers. I found this easy utility that will change your settings and/or fix your corrupt Registry, so that autorun works again. You can download it from The Software Patch. Run it, follow the prompts, and reboot. That's all it takes.
The Software Patch also has a handy tool to help you remove files that Windows XP wont let you delete. Once you tell the tool what file you want to delete, reboot your computer and your file will be deleted before Windows XP starts again.
