The first 3 times that a user logs on to a Windows XP Professional computer, they receive a balloon prompt for the Windows Tour.

To suppress the prompt for all new users:

1. Use Regedit to navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Applets\Tour. If the Tour key does not exist, use Edit / New / Key and type Tour.

2. Use Edit / New / Dword and type a Value Name of RunCount.

3. Double-click RunCount and set the data value to 0.

4. Press OK.

5. Exit the Registry Editor.

To suppress the prompt for an existing user, navigate to their Hive's Software\Microsoft\Windows\CurrentVersion\Applets\Tour key and perform steps 2 - 5.
