You want to turn off balloon tips, which frequently don't give any useful information, especially for experienced users, and are more distracting then they are useful, particularly when they show up in the Notification Area.
Using the Registry
1. Open the Registry Editor (Start-Run-regedit)and go to HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Explorer\Advanced.
2. Create a new DWORD value called EnableBalloonTips.
3. Give it a value of 0.
4. Exit the Registry and restart. Balloon tips will be turned off. To turn them on, either delete the DWORD value, or else give it a value of 1.
