In Microsoft Windows XP there is a feature known as 'Balloon Tips' that puts up little pop-ups when you hover the mouse over certain menu options, icons, toolbars etc which are designed to help people to understand what particular functions achieve, and also act as a memory jogger.
Many people like this idea, but just as many hate it and would rather not have these tips and with a little bit of work they can be removed - There are two different solutions here depending on whether you have Windows XP Home or Windows XP Professional
Note - to implement these changes you must be logged in with Administrator rights no matter which version of Windows you're using
Warning - This tweak involves direct editing of the Registry, if you are unsure of what to do then please do not proceed, and always make sure you have adequate backups in case of problems. NWC can accept no responsibilty for damage caused by trying to apply this tweak
