I go crazy looking at the balloon tips in Windows XP. So I found this little registry tweak to turn them off.
NOTE: Making changes to the registry can cause serious harm to your computer if done incorrectly. Always backup your registry before making any changes.
This littel tweak works great if you hate those Windows balloons that popup out of nowhere, with seemingly usefull information but in truth they are usually just annoying.
By changing putting the value to 0 we are telling it not to put the balloon tips up.
