As you may know, when you install Windows XP on a computer, it prompts you to take the Windows XP Tour. This prompt appears as a balloon that pops up from the Windows XP Tour icon in the notification area of the taskbar. By default, the prompt appears the first three times that someone logs on to the system.
If you've been using Windows XP for a while but have recently reinstalled the operating system, you may find this prompt annoying. If so, you can prevent it from appearing.
Follow these steps:
If you're installing Windows XP on a computer for a novice user and you want to increase the likelihood that he or she will take the Windows XP Tour, you can enter a higher number in the RunCount Value Data text box.
Note: Editing the registry is risky, so be sure you have a verified backup before saving any changes.
