Want to get rid of those nasty balloon tips, hovering over the task tray?
Here’s the registry command:
reg add "HKCUSoftwareMicrosoftWindowsCurrentVersionExplorerAdvanced" /t REG_DWORD /v EnableBalloonTips /d 0
If you’d wish to re-enable them again, this is the code
reg add "HKCUSoftwareMicrosoftWindowsCurrentVersionExplorerAdvanced" /t REG_DWORD /v EnableBalloonTips /d 1
